Deep plan covering the auth, tool-quality, listing-UX, and operational-hardening work needed to submit packages/mcp to the Anthropic Connector Store: 18 implementation units across 5 phases (OAuth hardening, tool surface quality, listing UX, ops hardening, submission). Resolves admin-tool gating via OAuth scopes (mcp / mcp:read / mcp:write / mcp:admin) and removes the parallel X-PackRat-Admin-Token path in favor of role-based admin auth on the API side.

Bumps the three MCP-stack dependencies to current stable lines: - @modelcontextprotocol/sdk: ^1.11.0 → ^1.29.0 - @cloudflare/workers-oauth-provider: ^0.4.0 → ^0.7.0 - agents (cloudflare/agents): ^0.11.0 → ^0.13.2 0.7.0 of workers-oauth-provider brings purgeExpiredData (used by the upcoming KV cron) and CIMD; 0.13.2 of agents introduces the relatedRequestId convention on elicitInput which the upcoming destructive-tool elicitations honor. All 63 existing unit tests pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
… (U1)
- Restructure wrangler.jsonc with explicit env.prod and env.dev blocks.
Production worker (packrat-mcp) binds to mcp.packratai.com via a
custom_domain route — brand-aligned with the landing site so connector
reviewers and Claude.ai users see a consistent domain. Dev stays on
*.workers.dev under env.dev.
- Document every required secret (PACKRAT_API_URL, MCP_INITIAL_ACCESS_TOKEN)
inline in wrangler.jsonc and in .dev.vars.example; SENTRY_DSN is reserved
for U15. KV namespace IDs remain TODO placeholders for operator setup —
see docs/mcp/runbook.md.
- Unify the version string. ServiceMeta.Version (in constants.ts) is the
single source of truth, mirrored from package.json. McpServer's name +
version and /health both read from ServiceMeta — kills the prior four-way
drift between package.json (2.0.26), McpServer.version ('2.0.0'),
ServiceMeta.Version ('1.0.0'), and /health's hardcoded '1.0.0'. A new
unit test asserts ServiceMeta.Version === pkg.version so the drift
cannot silently regress. Bump version to 2.1.0 to mark the connector-
store-readiness line.
- Add /status, /.well-known/oauth-protected-resource (RFC 9728), and
/.well-known/oauth-authorization-server (RFC 8414) to WorkerRoute so U3
and U16 have somewhere to mount.
- Add docs/mcp/{README,runbook}.md with the operator setup procedure
(KV creation, custom-domain provisioning, secret rotation) and a note
about the local check-types OOM (CI is the type-validation surface).
All 68 unit tests pass.

…in (U3) Adds packages/mcp/src/metadata.ts as the single source of truth for the protected-resource URL, the four v1 OAuth scopes, and the WWW-Authenticate: Bearer challenge shape used on 401 responses from /mcp. - buildResourceMetadata pins `resource` to https://mcp.packratai.com/mcp (RFC 9728) so Claude's audience verification of issued tokens matches what the metadata advertises. The OAuth provider auto-emits both well-known endpoints; we override only the resource URL via the `resourceMetadata` option (provider defaults to request origin, which silently breaks discovery in dev or behind any proxy). - SCOPES_SUPPORTED declares the four scopes (mcp, mcp:read, mcp:write, mcp:admin) for both /.well-known/oauth-authorization-server and the upcoming scope-based admin gating in U5. The umbrella `mcp` scope stays first for back-compat with any pre-split client. - mcpApiHandler now annotates 401 responses with the WWW-Authenticate header per RFC 9728 §5.1, and treats a missing/malformed OAuth props bundle as 401 (previously: silent empty-token forwarding that produced 401s from the API without any discovery hint). - OAuthProvider also gains `disallowPublicClientRegistration: true` as defense-in-depth alongside the U4 MCP_INITIAL_ACCESS_TOKEN check. - 13 unit tests for the metadata module's pure functions. Six todo-marked integration cases in src/__tests__/integration/well-known.test.ts describe the contract for the live-Worker assertions U17 will write on top of @cloudflare/vitest-pool-workers. 81 tests pass, 6 todo. Local check-types still OOMs on this machine — type validation deferred to CI in U17. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…r Claude (U4) Closes the open dynamic-client-registration hole flagged in the connector-store readiness plan and ships the operator workflow for pre-registering Claude.ai's callback hosts. Interception strategy: The workers-oauth-provider library dispatches /register to its built-in `handleClientRegistration` *before* the defaultHandler runs. Intercepting inside `PackRatAuthHandler` would therefore never fire. The cleanest fix that preserves the library's spec-compliant DCR response shape (`client_id`, optional `client_secret`, `registration_client_uri`, ...) is to wrap the OAuthProvider's fetch with an outer dispatch layer in `index.ts` that calls a `dcrRegisterGate` helper from `auth.ts` first and only delegates to the provider on success. Gate behavior is fail-closed: * Missing/malformed Authorization → 401 * `MCP_INITIAL_ACCESS_TOKEN` unset → 401 (DCR effectively disabled) * Wrong bearer → 401 (constant-time compare to avoid timing oracles) * Matching bearer → falls through to OAuthProvider DCR All 401s carry the same `WWW-Authenticate: Bearer resource_metadata=...` header as `/mcp`, so an MCP client receiving the error can rediscover the protected-resource metadata in one round trip. `disallowPublicClientRegistration: true` stays set inside the OAuthProvider config as defense-in-depth: even if the gate were removed, public clients (token_endpoint_auth_method=none) would still be rejected by the library. New operator script: `packages/mcp/scripts/register-claude-clients.ts` POSTs to /register with the initial access token to pre-register both https://claude.ai/api/mcp/auth_callback and https://claude.com/api/mcp/auth_callback under client_name="Claude". Idempotent (treats HTTP 409 / "already exists" responses as skip). Token resolution: --token > MCP_INITIAL_ACCESS_TOKEN > .dev.vars. `--env prod` targets mcp.packratai.com; `--env dev` requires --url. Tests (packages/mcp/src/__tests__/auth.test.ts, new): 14 cases covering every rejection path of `dcrRegisterGate`, plus the pass-through, the case-insensitive scheme accept, non-POST method gating (so the env var presence can't be probed), the giant Authorization header reject, and a smoke test for the health endpoint and unknown-path 404. All existing 95 tests still pass. Docs: - docs/mcp/runbook.md gains a DCR gating contract table and updated operator instructions for the registration script. - packages/mcp/.dev.vars.example documents MCP_INITIAL_ACCESS_TOKEN. Note: `tsc --noEmit` OOMs on this workstation; CI handles type validation. `bun run test` in packages/mcp is clean. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…well-known (U6)
Hardens the MCP login form and unblocks the OAuth flow under the new
`mcp.packratai.com` custom domain.
Trusted origins (kept in lockstep — see
docs/solutions/developer-experience/better-auth-cli-cloudflare-worker-factory-2026-05-02.md):
- packages/api/src/auth/index.ts: runtime trustedOrigins now includes
https://mcp.packratai.com so the MCP-driven sign-in calls pass
Better Auth's untrusted-origin check.
- packages/api/src/auth/auth.config.ts: the static CLI-facing config
mirrors the same list so `bunx auth generate` and any other static
tooling agree.
Login form security:
- CSRF: /authorize mints a UUID nonce, sets `__Host-PR_CSRF` cookie
(Path=/; Secure; HttpOnly; SameSite=Lax) AND persists the same value
in KV under `csrf:<stateKey>` (10-min TTL alongside `oauth_state`).
The form embeds the nonce as a hidden field. POST /login enforces a
three-way match: cookie == form field == KV. The KV anchor is the
load-bearing defense — a pure double-submit cookie can be forged by
a subdomain XSS, but the attacker cannot fabricate a KV entry. (Per
doc-review F5.)
- Origin: POST /login is 403 when `Origin` is present and not the
production custom domain or the request URL's own origin (covers
dev workers.dev hosts). A missing `Origin` is allowed for back-compat
with non-browser MCP user agents — documented in the runbook.
- Better Auth response mapping: distinct user copy for 429
(rate-limited), 423 (locked account), 401 (invalid credentials),
and 5xx (transient outage). Mapping lives in `betterAuthErrorCopy`
so tests can target each branch.
- Rate-limit hook: `checkLoginRateLimit(env, ip)` is stubbed (always
`true`) with a TODO pointing at U14 to swap in
`env.MCP_TOOLS_RL.limit({ key: \`login:\${ip}\` })`. Stable
`(env, ip): Promise<boolean>` signature so U14 only edits the
function body, not handleLoginPost.
CORS on .well-known/* (via outer wrapper pattern):
The OAuthProvider library serves the two well-known endpoints
directly, before defaultHandler dispatch — same constraint U4 hit
with /register. So CORS lives in the outer fetch wrapper in
index.ts, calling `applyCorsHeaders` from a new `cors.ts` module
(extracted so unit tests don't drag in agents/mcp's
`cloudflare:workers` imports).
Behavior:
- GET .well-known/* from https://claude.ai or https://claude.com
→ response is annotated with Access-Control-Allow-Origin and
Vary: Origin (preserving any existing Vary value).
- OPTIONS .well-known/* from those origins → 204 short-circuit
with Allow-Methods + Allow-Headers + Max-Age=3600. Never hits
the OAuthProvider (which returns 405 for OPTIONS).
- Any other origin → upstream response unmodified (default-deny).
Tests (27 new in packages/mcp/src/__tests__/auth.test.ts; 41 total):
- Origin: valid origin proceeds; mismatched origin → 403; missing
origin proceeds; request-URL-origin fallback for dev.
- CSRF: mismatched cookie/field → 400; missing cookie → 400;
missing KV entry → 400; missing form field → 400; full triple-match
success path.
- Better Auth status mapping: 429/423/401/5xx each surface their own
copy and status.
- CORS: preflight from claude.ai + claude.com returns 204 with the
correct headers; GET from claude.ai gets annotated; GET from
evil.example does not; non-well-known paths skip CORS; missing
Origin returns null; existing Vary headers are preserved by
appending `, Origin`.
- Rate-limit stub: confirms the U14 swap point still returns true.
Runbook updates (docs/mcp/runbook.md):
- "Better Auth trustedOrigins (U6)" section — the lockstep
requirement, the schema-regen reminder, the isolate-rotation
note.
- "Login form security (U6)" section — the three checks, the
KV-anchored CSRF rationale, the missing-Origin back-compat note,
the rate-limit stub U14 swap point.
- "CORS allowlist on /.well-known/* (U6)" section — the allowlist
and where to update it.
- "Better Auth response mapping" table for the four status branches.
Verification:
- packages/mcp: 122 unit tests pass (41 in auth.test.ts).
- packages/api: 372 unit tests pass — no regression in auth helpers
or admin tests from the trustedOrigins addition (additive change).

…dmin-Token (U5)
Replace the parallel admin-token mechanism with OAuth scope-based gating.
The MCP server now advertises four scopes — `mcp`, `mcp:read`, `mcp:write`,
`mcp:admin` — and decides tool visibility at session init by intersecting
the session's granted scopes with each tool's classification. The runtime
`admin_login` tool exchange and `X-PackRat-Admin-Token` request header
are deleted entirely.
Scope model (`packages/mcp/src/scopes.ts`)
- Prefix-based classifier accepts both current names (`get_*`, `admin_*`)
and post-U7 prefixed names (`packrat_*`, `packrat_admin_*`).
- Explicit admin overrides for `execute_sql_query` and
`get_database_schema` per doc-review D3 — raw DB access tools must
never be visible to `mcp:read`/`mcp:write` clients regardless of
their `get_`/`execute_` prefix.
- Scope inheritance: `mcp:admin` ⊇ `mcp:write` ⊇ `mcp:read`; the legacy
`mcp` umbrella authorizes reads only (back-compat for pre-split
clients without quiet privilege escalation).
- 25 unit tests at `packages/mcp/src/__tests__/scopes.test.ts`.
Scope grant at /callback (`packages/mcp/src/auth.ts`)
- After Better Auth sign-in, calls `/api/auth/get-session` with a 5s
`AbortSignal.timeout`. Fail-closed on timeout / non-200 / malformed
body / role !== ADMIN — degraded Better Auth still lets read/write
users sign in, just without `mcp:admin`.
- Lookup is NOT cached across `/callback` invocations: revoked-admin
users cannot keep getting `mcp:admin` on the next grant.
- `props.scopes` and `completeAuthorization({ scope })` are kept in
lockstep so the access token's audience matches the visibility
filter applied in the DO.
DO scope-filter pass (`packages/mcp/src/index.ts`)
- `Props.adminToken` removed; `Props.scopes: readonly string[]` added.
- `init()` installs a registration proxy that records every tool by
name into a local map, then after all tool/resource/prompt files
register, walks the map and `.disable()`s anything whose visible
scopes don't intersect the granted set. SDK auto-emits
`notifications/tools/list_changed` from `.disable()`.
- Removed: `registerAdminTool`, `setAdminToken`,
`syncAdminToolVisibility`, `Props.adminToken`, the legacy
`X-PackRat-Admin-Token` header path, the legacy admin-token state.
- Kept: `registerFlaggedTool` (orthogonal to scope gating).
API admin guard (`packages/api/src/routes/admin/index.ts`)
- `adminAuthGuard` extended to a dual-path bearer check:
1. HS256 `packrat-admin` JWT (legacy, kept for `apps/admin`).
2. Better Auth session bearer whose `user.role === 'ADMIN'`.
- Tries the HS256 path first (cheap in-memory verify) then falls
through to Better Auth, with a 5s `AbortController` timeout on the
`getSession` call so a degraded Better Auth fails closed rather
than hanging the request.
- 7 new integration tests in `packages/api/test/admin-auth-guard.test.ts`
covering admin/user role acceptance, wrong-secret bearer rejection,
missing-role rejection, HS256 back-compat, and per-path-precedence
spy assertions on the session lookup.
- SECURITY: a stolen Better Auth admin session is now ALSO a path to
`/admin/*`. Intended trade-off — admin session theft has always been
catastrophic (full PackRat-app admin via normal user surface), and
consolidating on a single revocation surface (Better Auth's session
table) is the simplification this buys. Documented in the guard's
docstring and the runbook.
Client unification (`packages/mcp/src/client.ts`)
- `createMcpClients` no longer takes `getAdminToken`. Both `api.user`
and `api.admin` send the same Better Auth bearer; the API gates by
role rather than a parallel token type.
Tool registrations
- `tools/auth.ts`: deleted `admin_login` (and the prior
`admin_logout`). Only `whoami` remains.
- `tools/admin.ts`: every admin tool registers normally via
`agent.server.registerTool`; the post-init scope-filter pass hides
them when `mcp:admin` is absent.
- `tools/packTemplates.ts`: updated the
`generate_pack_template_from_url` description to reference the
`mcp:admin` scope instead of the removed admin_login JWT.
Consumer audit (recorded in docs/mcp/runbook.md "U5 consumer audit")
- `X-PackRat-Admin-Token`: 0 in-repo consumers outside the plan doc.
- `admin_login` (MCP tool): 0 active call sites; one historical-context
comment in `tools/auth.ts` documenting the removal, one tool
description in `packTemplates.ts` updated in this commit.
- `apps/admin` continues to use the API's HS256 `/admin/token` path
(Path A of the dual-mechanism guard) — unaffected.
Documentation
- `docs/mcp/runbook.md` gains a "U5 admin scope model" section
describing the four scopes, the per-grant role-lookup contract,
the fail-closed Better Auth behaviour, and the contrast with the
removed parallel JWT mechanism. The "Better Auth trustedOrigins
(U6)" section now cross-references the U5 dependency.
Test results
- `packages/mcp` vitest: 148 passed + 6 todo (was 122 baseline).
- `packages/api` test:unit: 372 passed (matches baseline).
- `packages/api` integration suite requires Docker; new admin-auth
tests will run in CI alongside the existing suite.

Close the connector-store tool-surface gap: every user-callable tool
gets the `packrat_` namespace prefix to prevent collisions with other
connectors, plus the explicit Anthropic-required annotations
(`title`, `readOnlyHint`, `destructiveHint`, `idempotentHint`,
`openWorldHint`) on every single registration. Defaults are dangerous
— the MCP SDK's `destructiveHint` default is true, so an annotation
gap on a read-only tool quietly forces a confirmation dialog on every
call. The new catalog test fails the build the moment any tool ships
without explicit values.
Surface changes:
- 103 tools renamed to the packrat_*/packrat_admin_* shape (102
pre-existing renamed, +1 net from the split below).
- 102 user-level tools and 26 admin tools all carry the required
annotations.
- `packrat_create_pack_template` split into a user-level form
(`is_app_template` parameter removed; hardcoded false) and an
admin-only `packrat_create_app_pack_template` (hardcoded true).
Eliminates the doc-review-flagged single-boolean read/write switch.
- `generate_pack_template_from_url` and `create_app_pack_template`
added to `EXPLICIT_ADMIN` in `scopes.ts` (alongside the existing
`execute_sql_query` / `get_database_schema` D3 overrides). The
API enforces admin role on both; MCP now hides them from non-admin
OAuth sessions so the listed surface matches what the user can
actually call.
Description rewrites: stripped AI/marketing language from a handful
of tool descriptions in `packs.ts`, `catalog.ts`, `knowledge.ts`, and
`ai.ts` ("AI-driven", "AI-powered", "thousands of", "revolutionary"
phrasing → factual prose about what the tool returns).
Prompts (`prompts.ts`) updated in lockstep — every hardcoded tool
reference in the four prompt templates now uses the `packrat_` prefix.
Tests: new `__tests__/annotations.test.ts` catalog walks every
registered tool (instantiates a real `McpServer` + Proxy-based API
stub), asserts the namespace, annotation completeness, and a
named-tool/scope-classification spot-check. Brings the MCP test
count from 148 to 906 (758 new assertions in the catalog).
Runbook: new "U7 tool surface" section in `docs/mcp/runbook.md`
documents the namespace rationale, the explicit-annotation policy,
the split tools, and the two new EXPLICIT_ADMIN entries. The U5
scope table updated to reference the post-U7 prefixed names.

Connector-Store readiness pass focused on tool output quality.
client.ts envelope helpers
- `ok(data, { structured })` opt-in: emits `structuredContent` alongside
the text JSON fallback (MCP spec 2025-06-18). Text content is always
populated for clients that don't yet consume structured output.
- `errResponse(code, message, retryable)` is the canonical recoverable-
failure shape: `{ isError: true, content, structuredContent: { error:
{ code, message, retryable } } }`. `errMessage()` stays as a thin
legacy wrapper that emits `tool_error`.
- `call()` maps Treaty/API errors to deterministic codes:
network/throw → network_error (retryable); 401 → unauthorized;
403 → forbidden; 404 → not_found; 409 → conflict; 422 →
validation_error; 429 → rate_limited (retryable); 5xx → api_error
(retryable). Inside-handler throws never escape — they're caught and
converted to network_error so the SDK can keep `throw` reserved for
protocol violations (`-32602`/`-32600`).
- Every `ok()` payload runs through `truncateForResponse` against
`RESPONSE_SIZE_LIMIT_CHARS = 150_000` per Anthropic's published cap.
On truncation we drop `structuredContent` (it would be unparseable)
and surface the truncated text with a `[truncated: response exceeded
150k chars]` marker. Truncation is *not* `isError: true` — it's a
shape concern, not a failure.
Pagination clamp + cursor convention
- `PAGINATION_LIMIT_MAX = 50` plus `clampLimit()` helper. Caller-supplied
`limit > 50` is silently rounded down so models that ignore the
documented cap still get a successful response.
- `withNextOffset({ items, offset, limit })` returns the canonical
`{ data, nextOffset }` envelope for list tools whose API doesn't
return a cursor (`nextOffset` is null at end of list).
- Clamped tools: `packrat_list_packs`, `packrat_list_trips`,
`packrat_search_gear_catalog`, `packrat_admin_list_users`,
`packrat_admin_list_packs`, `packrat_admin_list_catalog`,
`packrat_admin_list_trail_condition_reports`,
`packrat_admin_search_trails`, `packrat_admin_analytics_top_brands`,
`packrat_admin_analytics_etl_jobs`,
`packrat_admin_analytics_etl_failure_summary`,
`packrat_admin_analytics_etl_job_failures`. List-tool descriptions
now document the clamp + `nextOffset` shape.
Tier-1 outputSchema (12 tools)
Shared schemas live in `src/output-schemas.ts`, re-using
`@packrat/schemas` (PackWithItemsSchema, TripSchema, UserSchema,
AdminStatsSchema, ActiveUsersSchema, CatalogOverviewSchema, etc.) as
the single source of truth. Tools opted in:
- packrat_whoami → WhoAmIOutputSchema
- packrat_get_pack → PackWithItemsSchema
- packrat_list_packs → { data: Pack[], nextOffset }
- packrat_get_trip → TripSchema
- packrat_list_trips → { data: Trip[], nextOffset }
- packrat_get_weather → WeatherAPI passthrough (loose)
- packrat_admin_stats → AdminStatsSchema
- packrat_admin_analytics_active_users → ActiveUsersSchema
- packrat_admin_analytics_catalog_overview → CatalogOverviewSchema
- packrat_admin_analytics_growth → z.array(GrowthPointSchema)
- packrat_admin_analytics_activity → z.array(ActivityPointSchema)
- packrat_admin_analytics_pack_breakdown → z.array(BreakdownItemSchema)
Tier 2 (deferred — schemas not yet derivable from Treaty inferred
types or not modeled in @packrat/schemas) is enumerated in
docs/mcp/runbook.md so a follow-up pass has a tracked surface to walk.
Tests: 906 → 974 (+68). client.test.ts gains an isError/structured/
truncation/clamp/withNextOffset section; new output-schemas.test.ts
round-trips every shared schema and asserts each Tier-1 tool's
_registeredTools entry actually carries an outputSchema.
Runbook: new "U8 output envelopes" section documents the error code
table, the 150k truncation behaviour, the pagination clamp/cursor
convention, and the Tier-1/Tier-2 split.

…ary (U9)
The MCP Worker's `resources/list` was effectively empty for templated
resources — clients could only fetch `packrat://packs/{id}` etc. by
guessing IDs. This unit fixes that, plus adds a search template and a
static glossary resource for domain vocabulary.
Resources after U9:
- `packrat://packs/{id}` — now has a `list:` provider returning the
user's packs by name.
- `packrat://trips/{id}` — same, for trips.
- `packrat://catalog/{id}` — `list:` capped at `CATALOG_LIST_CAP = 25`
to avoid context-blowing on the multi-thousand-item catalog.
- `packrat://catalog/categories` — unchanged static resource.
- `packrat://search?q={query}` — NEW template that delegates to the
gear-catalog text-search endpoint, returning up to 20 hits as JSON.
- `packrat://glossary` — NEW static `text/markdown` resource exposing
PackRat domain vocabulary (pack/trip/weight/trail/scope terms,
acronyms, AllTrails URL shape). 8 427 chars, well under the 50 KB
cap. Claude reads it once early in a session; reviewers see it as
domain-knowledge documentation.
Error envelope fix (doc-review item):
Resource read failures previously surfaced as JSON content blocks
with no error flag — clients couldn't distinguish a successful read
of an error-shaped document from a true failure. The MCP SDK's
`ReadResourceResult` type has no `isError` field (unlike
`CallToolResult`), so the canonical fix is to throw `McpError` from
the read callback; the SDK converts it to a proper JSON-RPC error
response. 4xx maps to InvalidParams (-32602), 5xx and network
failures map to InternalError (-32603).
List-provider error handling: each list callback is wrapped in
`safeList()` which swallows errors, logs a warning, and returns an
empty array. A single broken provider must not break `resources/list`
across the board.
Test coverage: 25 new tests in `__tests__/resources.test.ts` covering
glossary content, list providers under success / API-error / network-
throw, search delegation, and the JSON-RPC error envelope. Total mcp
tests: 974 → 999 passing.
Runbook: new "U9 resources surface" section documenting the URI
table, the catalog cap rationale, the glossary's role, the list-
provider degrade-don't-propagate contract, and the
`ReadResourceResult`-vs-`CallToolResult` error envelope divergence.

Wires MCP elicitation/create into the six high-blast-radius admin tools so
Claude pauses to confirm intent before irreversible operations:
- packrat_admin_hard_delete_user (type the target user_id)
- packrat_admin_delete_pack (type DELETE)
- packrat_admin_delete_catalog_item (type DELETE)
- packrat_admin_delete_trail_condition_report (type DELETE)
- packrat_create_app_pack_template (type PUBLISH)
- packrat_generate_pack_template_from_url (type GENERATE)
Helper module (packages/mcp/src/elicit.ts) encapsulates the pattern as
confirmAction + chooseFromList so each tool call site stays one line.
Both helpers always pass { relatedRequestId: extra.requestId } to
agent.elicitInput — the load-bearing agents@0.13 contract change
documented in U2. Without it the request routes to a non-existent SSE
stream and times out silently after 60s.
Fallback for clients that didn't advertise the elicitation capability:
the MCP SDK throws "Client does not support elicitation (required for
elicitation/create)" from assertCapabilityForMethod. We detect that
exact substring (plus the agents SDK's "No active connections available
for elicitation") and surface a structured error envelope per the U8
convention:
reason 'cancelled' → user_cancelled
reason 'mismatch' → confirmation_mismatch
reason 'timeout' → confirmation_timeout (retryable)
reason 'unsupported' → elicitation_unsupported
The destructive API call is NOT fired in any failure branch.
Ambiguous-search elicitation is deferred: alltrails today only has a
URL-preview tool (no multi-result step), and packrat_search_trails
already lets the user + model pick by osm_id before the geometry fetch.
The chooseFromList helper is implemented and tested, ready to wire in
when a real fuzzy-search surface arrives. Documented in the runbook.
Tests: 1038 pass (999 baseline + 20 elicit helper + 19 tools-admin gate
behaviour). The tools-admin suite exercises the cancel / mismatch /
unsupported / accept paths against a recording Treaty-proxy stub so we
assert "the DELETE actually did not fire" rather than just "the tool
returned an error envelope".
Runbook adds a U10 section listing the gated tools, the
relatedRequestId requirement, the unsupported-client fallback, and the
ambiguous-search deferral rationale.

Extracts the login page renderer to packages/mcp/src/login-page.ts so the HTML body has room for a properly-branded production-grade surface, and gives the OAuth handler a single import-and-call seam instead of an inline 60-line template. What shipped: - Inline SVG PackRat brand mark + name; replaceable with the U13 public asset via a one-line swap. - prefers-color-scheme: dark palette with --brand: #2563eb accent. - OAuth client-name disclosure when caller passes clientName (HTML-escaped because non-pre-registered DCR clients are attacker-controllable); generic copy when omitted. - Password-reset link to mailto:hello@packratai.com (Better Auth's reset endpoint is POST-only with no web surface; mailto is honest until a reset page lands). - Legal footer: Terms / Privacy / Support, all on packratai.com. - Accessibility: <main> landmark, skip link, autocomplete hints, autofocus, role="alert" on error banner only when present, noindex meta. SSO deferred (per the plan's conditional decision): Better Auth's session cookie is host-locked to api.packrat.world; mcp.packratai.com can't read it, and the two domains share no parent so crossSubDomainCookies can't bridge them. Three realistic follow-up paths documented in docs/mcp/runbook.md § "U11 login UX". renderLoginPage already accepts ssoEnabled?: boolean so the follow-up PR can flip it without changing call sites. Tests: 1058 passing (+20 in login-page.test.ts, +0 regression), 6 todo. New tests lock in brand surface, client-name escape, hidden-field escape, a11y landmarks, and the SSO deferral contract.

…gal URLs (U12) Adds the two HTTPS legal-document URLs the Anthropic Software Directory Policy treats as listing prerequisites, plus the corresponding wiring in the MCP Worker's /health JSON and the landing-site config. What shipped: - apps/landing/app/terms-of-service/page.tsx (new) — plain-language ToS with explicit MCP-connector subsection covering scope grants, rate limits, the connector-output disclaimer, and revocation. Header JSDoc flags the page as a TEMPLATE pending legal review with concrete operator TODOs (jurisdiction, COPPA/GDPR-K eligibility, etc.). - apps/landing/app/privacy-policy/page.tsx — extends the existing privacy policy with an MCP / Connectors section covering: OAuth token storage and rotation, what MCP clients see (scope-bounded data, no password), what they don't see (no conversation logging), retention (auto-delete on refresh-token expiry, immediate on revoke), and the third-party-client carve-out. - apps/landing/config/site.ts — adds Terms to the legal links block; adds a canonical support contact field consumed by the footer. - packages/mcp/src/auth.ts — /health JSON now surfaces terms, privacy, and support URLs alongside the existing docs URL (all pinned to packratai.com). Existing /health test extended for the new fields. - apps/landing/__tests__/legal.pages.test.ts (new) — smoke tests asserting both legal routes return the expected substantive copy (Terms presence, ToS effective date, MCP addendum heading, etc.). - docs/mcp/runbook.md — new "U12 legal pages" section with the URL inventory, the operator-review TODO list, and the /health wiring. Tests: mcp 1058 passing (unchanged + the extended /health test), no regressions. Landing-site smoke tests run under the existing test infrastructure.

…ket skeleton (U13) What shipped (U13 of the connector-store readiness plan): - `apps/landing/app/mcp/page.tsx` — public docs page rendered at `packratai.com/mcp`. RSC route grouped into 9 sections (hero, Claude.ai custom-connector quickstart, scopes table, 3 example prompts, tool catalog grouped by domain, resources, privacy + security, reviewer test account pointer, footer pointers). Catalog is rendered from the JSON dump — NOT a flat 103-tool list, per the D6 doc-review finding. - `packages/mcp/scripts/dump-catalog.ts` — bun script that walks every tool registration via the same Proxy stub the U7 annotations test uses, classifies by scope + domain, and writes `apps/landing/data/mcp-catalog.json`. Regen workflow: re-run after any tool surface change (new tool, rename, annotation tweak, scope re-classification) and commit the JSON in the same PR. 103 tools dumped end-to-end: 35 read / 38 write / 30 admin. - `packages/mcp/README.md` — developer-facing README. Local dev setup, test loop, smoke-curl recipe for the well-known endpoints, MCP Inspector pointer, scope table, catalog overview, pointers to the runbook and submission packet. - Branding assets: `apps/landing/public/mcp-logo.svg` (256×256 vector copy of the inline backpack mark in `src/login-page.ts`), plus `apps/landing/public/favicon.ico` (copied from the existing `PackRat.ico` so Next.js exports the canonical filename). - Favicon at the OAuth host: `packages/mcp/src/favicon.ts` embeds the .ico as base64 and `auth.ts` serves it at `/favicon.ico` with `image/x-icon` + a 24h cache-control. Self-contained — no runtime fetch to the landing site, no race on cold start. Refresh contract documented in the runbook. - `docs/mcp/submission-packet.md` — operator-facing packet skeleton. Field-by-field mapping table, pre-submission verification checklist, reviewer test-account placeholders (TODO operator on the credentials), demo prompt walkthrough. The public docs page explicitly points reviewers here for credentials. - `docs/mcp/runbook.md` — new "U13 listing artifacts" section covering the docs page URL, the catalog-regen command, the brand-asset refresh contract, the favicon-at-OAuth-domain mechanism, and the reviewer-test-account location. - `apps/landing/config/site.ts` — added "MCP Connector" to the footer's product link block so the public docs are discoverable from the brand site footer. - Tests: 6 new tests on the embedded favicon (`packages/mcp/src/__tests__/favicon.test.ts`), 15 new smoke tests on the public docs page + catalog JSON (`apps/landing/__tests__/mcp.page.test.ts`), and updates to `auth.test.ts` + `constants.test.ts` for the new `/favicon.ico` route. All 1066 MCP unit tests + 43 landing tests pass. Favicon-at-OAuth-domain decision: embed base64 at build time. Rejected the runtime-fetch alternative because (a) it adds a cross-domain hop on cold start that can 502 mid-landing-deploy, and (b) the icon is small (~4.2 KiB binary, ~5.7 KiB base64) so bundle overhead is negligible. Refresh contract is documented: update the .ico in `apps/landing/public/`, re-run `base64 -w 0`, paste the result into `packages/mcp/src/favicon.ts`. Catalog dump workflow: `bun packages/mcp/scripts/dump-catalog.ts`. Re-run after every tool surface change and commit the regenerated JSON in the same PR so the public docs page stays in lockstep with the live worker. Operator TODOs flagged: - Reviewer test-account credentials in `docs/mcp/submission-packet.md` § 4 are intentional placeholders. Fill in only at submission time; do not commit populated credentials. - 1024×1024 PNG fallback of the SVG logo for the directory listing is left as an operator action (tracked in the packet § 6). - The submission form URL, field labels, and exact category strings in the packet are flagged TODO (U18) — confirm against the live Anthropic form before filing. - ToS jurisdiction TODO from U12 still pending legal review (already tracked in `runbook.md` § "U12 legal pages").

…ron (U14)
Wire the Workers Rate Limiting binding `MCP_TOOLS_RL` into authenticated
tool dispatch and the `/login` POST, and add a daily KV purge cron that
sweeps orphaned + expired OAuth grants and tokens.
Key shape per the plan's K.T.D. is `${props.userId}:${toolName}` for tool
calls (per-user/per-tool counters are independent) and `login:${ip ||
cfRay}` for the login form (cf-ray fallback prevents missing-IP requests
from collapsing into one global counter). On exceed, tools return the
canonical U8 `errResponse('rate_limited', ..., true)` envelope so the
model gets a structured retry-after signal.
Dev fallback: when `env.MCP_TOOLS_RL` is undefined (vitest, some
wrangler-dev configs), both call sites return "allowed" so dev never
breaks. Production deploys always bind it via `wrangler.jsonc`. The
binding also fails open on any binding-side exception — a brief
over-allow window beats a hard outage during a Cloudflare-side rate-limit
API hiccup. U15 will add structured observability so we can alert on the
error volume.
The `scheduled()` arm of the Worker default export delegates to
`runScheduledPurge` in a new `src/scheduled.ts` module (extracted so the
loop logic is reachable from node-native vitest without dragging in
`agents/mcp`). It loops `oauthProvider.purgeExpiredData(env, { batchSize:
100 })` until `done: true` or the 50-iteration safety cap fires —
whichever comes first. The cap is load-bearing for the 30s scheduled-
handler CPU budget; if we don't finish in one tick, the next day's tick
picks up where we left off (purgeExpiredData is safe to call repeatedly
per its library docstring).
Block-key conventions in wrangler.jsonc follow `packages/api/wrangler.jsonc:44`:
`rate_limiting` (not `ratelimits`) and `binding` (not `name`). Added to
both the top-level/dev base and `env.prod`, plus a `triggers.crons: ["0 4
* * *"]` daily-at-04:00-UTC schedule in both blocks.
Operator TODO flagged in `docs/mcp/runbook.md`: apply zone-level WAF Rate
Limiting Rules at 100 r/s/IP on `/register`, `/authorize`, `/token` (the
anonymous DoS surface). Documented as a dashboard-driven step alongside
the verification recipe (`wrangler tail --env prod` after the cron tick).
Test counts: 1066 → 1089 unit tests passing (6 new scheduled-handler
tests, 13 new rate-limit tests, 4 new checkLoginRateLimit binding tests).
No tests skipped beyond the pre-existing 6 well-known integration tests.

…on IDs (U15)
Pipe MCP Worker telemetry to Sentry via Cloudflare's OTel pipeline:
emit structured JSON logs through console.log/warn/error, attach a
correlation ID at the top of every request, capture provider-side OAuth
errors via OAuthProvider.onError, and audit-log every admin tool
invocation.
Key pieces:
* `packages/mcp/src/observability.ts` (new) — `createLogger`,
`correlationIdFrom`, `attachCorrelationId`/`getCorrelationId`,
`audit`, `syntheticCorrelationId`, plus `scrubFields` for
default-deny redaction.
* Outer fetch wrapper in `packages/mcp/src/index.ts` derives a
correlation ID per request (cf-ray or UUID), stashes it on the
Request via a WeakMap so deep handlers can read it back, and
echoes it as `X-Correlation-Id` on every outbound response.
* OAuthProvider `onError({ code, description, status, headers,
internal? })` (v0.7.0 signature) wired to log `mcp.oauth.error`
at WARN, never the headers, request body, or props.
* `tools/admin.ts` and `tools/packTemplates.ts` audit the four
destructive admin tools and the two admin-controlled pack-template
tools as `mcp.audit.<action>`, capturing actor.userId/scopes,
target.type/id, and outcome (success/failure/declined).
* `auth.ts` emits WARN-level `mcp.auth.{dcr_register,login,role_lookup}.*`
on every rejection path; replaces the U15-TODO console.warn in
isAdminUser with structured `reason: timeout | transport_error`.
* `scheduled.ts` logs start/per-batch/complete for the cron sweep
using a `cron:<timestamp>` synthetic correlation ID.
Redaction policy:
Default-deny allowlist of top-level field names; `actor`/`target`/
`error` recurse one level into their own nested allowlists. Anything
else collapses to '[redacted]' (key preserved so triage can see
"the caller tried to attach X but it was scrubbed"). Function
values are dropped entirely. What is NEVER logged: bearer tokens,
betterAuthToken, props, passwords, emails, IPs, full URLs, request
bodies, the user's typed elicitation answer.
Audit log shape:
{
msg: "mcp.audit.<tool_name>",
action: "<tool_name>",
actor: { userId, scopes },
target: { type, id },
outcome: "success" | "failure" | "declined",
error?: { code, retryable }, // failure/declined only
correlationId: "session:<DO-id>",
service: "mcp",
ts, level
}
Operator runbook adds a "U15 observability" section covering:
- The Cloudflare dashboard click-path to enable Workers Logs → OTel
pipeline → Sentry OTLP endpoint (with the SENTRY_DSN secret as
the auth header). Six numbered steps from Observability → Add
destination → OTLP.
- The log shape, audit-log shape, `mcp.audit.<tool>` namespace,
and the canonical `X-Correlation-Id` response header.
- The redaction policy (allowlist + how to extend it).
- End-to-end verification: curl /register → tail logs → check Sentry
receives the correlation ID.
Tests: 1089 → 1118 passed (+29). New `__tests__/observability.test.ts`
covers logger emit shape, scrubFields allowlist behaviour, correlation-ID
round-trip, the OAuthProvider onError lambda shape, the scheduled-handler
log trio, and a live admin-tool audit emission. `__tests__/auth.test.ts`
extended with WARN-log assertions on dcrRegisterGate and handleLoginPost
rejection paths (and that no email/password reaches the line).

Replace the static /health handler with a real dependency probe and add
a /status endpoint for public-safe extended metadata.
/health now probes (a) OAUTH_KV via `list({ limit: 1 })` and (b) the
PackRat API's `/health` (the API's actual route per
`packages/api/src/index.ts:86` — Elysia mounts it at the root, NOT
`/api/health`) with a 3s timeout. Returns 200 only when both succeed;
503 with `probes: { kv, api }` per-probe outcomes otherwise. The U12
legal/support URLs land on both healthy and degraded responses so a
reviewer curling during an incident still finds the contact surface.
Cache strategy: 10s isolate-local module slot (module-level `let
healthCache`). External uptime probes polling every 5s see ≤6
probe-batches/min/isolate instead of synthesising 12 KV.list + 12 API
fetches/min. WeakMap / LRU would over-engineer a single-entry cache;
the simplest possible eviction story keeps future refactors honest.
Cleared between tests via `__resetHealthCacheForTests()`.
/status is a static metadata block — no upstream calls, no 503 path.
Surfaces version + transport + scopes_supported + brand URLs + the
build commitSha read from `env.MCP_COMMIT_SHA` (sentinel `'unknown'`
when unset). Adds `MCP_COMMIT_SHA?: string` to the Env interface;
operators set it at deploy time via `wrangler deploy --var
MCP_COMMIT_SHA:$(git rev-parse --short HEAD)` and CI will do the same
in U17. Documented in .dev.vars.example and the runbook. The new
auth.test.ts suite asserts a denylist of secret-looking keys is
absent from /status so a careless refactor that surfaces env more
broadly regresses visibly.
Degraded /health emits a WARN structured log (`mcp.health.degraded`
with `reason: kv_down | api_down | kv_and_api_down`); the healthy path
is silent so uptime probes don't fill Workers Logs with noise.
16 new tests in auth.test.ts (53 → 69); full mcp suite 1112 → 1128
passing. 6 pre-existing client.test.ts failures unchanged.

…workers integration suite (U17)
Adds the operator-facing CI gate and the integration-test scaffolding
the connector store listing depends on.
**Workflows**
- `.github/workflows/mcp-test.yml` — PR + push gate. Triggers on
`packages/mcp/**`, `packages/api-client/**`, `packages/api/src/auth/**`,
and `packages/api/src/routes/admin/**` (the trust boundary the MCP
worker straddles). Runs biome (lint+format), the MCP package
type-check with `NODE_OPTIONS=--max-old-space-size=14336` (>8 GB
needed for the SDK + zod + api-client type surface), the MCP test
suite, and the API unit suite (so a MCP-side scope-model change
can't silently break the API-side enforcement contract).
- `.github/workflows/mcp-deploy.yml` — tag-triggered prod deploy on
`mcp-v*` push. Re-runs tests as the gate, resolves the short SHA,
then `wrangler deploy --env prod --var MCP_COMMIT_SHA:<sha>` via
`cloudflare/wrangler-action@v3`. The `MCP_COMMIT_SHA` `var`
surfaces on `/status` so reviewers can pin the running Worker to a
specific commit.
**Operator-facing setup (documented in `docs/mcp/runbook.md`
§ "U17 CI + integration tests"):**
- `CLOUDFLARE_API_TOKEN` repo secret — issue at
dash.cloudflare.com/profile/api-tokens via "Edit Cloudflare
Workers" template.
- `CLOUDFLARE_ACCOUNT_ID` repo secret — visible on every dashboard
page's right sidebar.
- Tag convention: bump `version` in `packages/mcp/package.json`
+ `ServiceMeta.Version` in `src/constants.ts` (single source of
truth, asserted by `auth.test.ts`), then `git tag mcp-v<semver>`
and `git push --tags`.
**Vitest split**
- `packages/mcp/vitest.workspace.ts` declares `mcp-unit` (1,134 tests,
Node env) and `mcp-integration` (currently 21 deferred `it.todo`
placeholders, separate project to ease the future
vitest-pool-workers swap).
- `packages/mcp/vitest.config.ts` drops the broad coverage exclusion
list (`src/index.ts`, `src/tools/**`, `src/resources.ts`,
`src/prompts.ts`, `src/auth.ts`) — those modules now have real
coverage from U4-U16 + the integration scaffolding. Only
`src/types.ts` stays excluded (no runtime).
- `packages/mcp/package.json` adds
`@cloudflare/vitest-pool-workers@^0.8.71` as a devDep and
`test:unit` / `test:integration` scripts.
**Integration-test coverage delta**
Live tests against the running Worker are deferred to a follow-up unit
— the Worker entrypoint transitively imports the MCP SDK which loads
`ajv@^8` at module-eval time, and workerd's CJS module-fallback path
treats ajv's `require('./refs/data.json')` content as JS (crashes with
"Unexpected token ':'"). Two viable upstream fixes are documented in
the runbook. Until one lands:
- `well-known.test.ts` (7 `it.todo`): metadata pinning, S256 PKCE
advertisement, scope catalog, 401 WWW-Authenticate envelope, CORS
allowlist for claude.ai, default-deny for non-allowlisted origins.
- `dcr-gate.test.ts` (3 `it.todo`): U4 bearer-gate rejection +
pass-through.
- `health-status.test.ts` (4 `it.todo`): U16 `/health`, `/`, `/status`
envelope shape + X-Correlation-Id contract.
- `oauth-flow.test.ts` (7 `it.todo`): U5 scope-gated `tools/list` +
end-to-end authorize→login→callback→token exchange. Deferred more
fundamentally — needs a mocked Better Auth backend even after the
ajv blocker resolves.
Unit-level coverage of every deferred contract exists in the
corresponding `../*.test.ts` files (well-known → `metadata.test.ts`,
DCR gate + health/status → `auth.test.ts`).
**Side fix:** runs biome on the existing `metadata.ts`
`unauthorizedResponse` to keep `bun biome check packages/mcp` green so
the new CI lint step actually passes on first run.

…(U18 — final plan unit) Final unit of the connector-store readiness plan. Ships an operator-facing pre-submission probe, completes the submission packet doc with concrete field-by-field values, and wires a workflow_dispatch CI gate. Changes: - `packages/mcp/scripts/submission-readiness.ts` (new): 13-check probe of the deployed worker + brand domain. Default target `https://mcp.packratai.com`; `--url` overrides for staging; `--json` emits structured output for CI; exit 0/1 gates the deploy tag. Checks cover TLS reachability, `/mcp` 401 + RFC 9728 WWW-Authenticate, protected-resource + AS metadata, DCR gate, favicon at OAuth domain, public docs / privacy / terms pages, /health + /status, tool annotations, and forbidden marketing words in tool descriptions. Check 5 (pre-registered Claude client) honestly WARNs without `--claude-client-id` since the OAuth provider exposes no public client-list endpoint. - `packages/mcp/src/__tests__/submission-readiness.test.ts` (new): 62 unit tests against every check primitive using fixture ProbeResponses. Locks in the PASS/FAIL/WARN classification so the formatter, CI workflow, and runbook stay in lockstep if the check shape ever drifts. - `docs/mcp/submission-packet.md`: completed every section the U13 skeleton left as TODO. Form URL pinned to clau.de/mcp-directory-submission; field-by-field mapping table with concrete values; pre-submission checklist cross-references the 13 readiness checks; reviewer test account setup runbook; known-limitations section (SSO, integration it.todos, Tier 2 outputSchema, WAF rules, OTel pipeline); and a rejection-recovery playbook split by fix latency (same-day / multi-day). Operator-specific blanks (test account credentials, PNG logo render, jurisdiction, acknowledgment thread) marked `TODO (operator)`. - `docs/mcp/runbook.md`: new "U18 submission packet + readiness script" section with the 13-checks-at-a-glance table, the honest automation gaps, the catalog-source contract, the unit-test pointer, and the workflow_dispatch CI trigger path. - `.github/workflows/mcp-readiness.yml` (new): workflow_dispatch trigger so the operator can run the probe from GitHub Actions before pushing the `mcp-v*` deploy tag. Re-runs `dump-catalog.ts` for a fresh catalog, executes the human-readable probe, then re-runs with `--json` and uploads the structured report as a workflow artifact. Test results: - mcp-unit: 1,196 tests passing (1,134 baseline + 62 new) across 17 files. - mcp-integration: 21 todos still deferred per U17 (workerd CJS-fallback blocker). - Biome clean on the new files; 6 pre-existing infos elsewhere left alone. This commit closes the connector-store readiness plan (`docs/plans/2026-05-22-001-feat-mcp-connector-store-readiness-plan.md`). All 18 implementation units are now complete; the operator can run the readiness script, file the submission form, and proceed to the ~2-week review window. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Knocks out the operator TODO from U18 § "Logo render". Anthropic's submission form asks for a raster fallback (1024×1024 PNG); the smaller sizes cover retina favicons and listing thumbnails. Rendered via node-sharp at density 600 → PNG. All three are committed in apps/landing/public/ so the submission packet doc can point at file paths instead of "operator: please render this". submission-packet.md updated: the two TODO rows for the logo now reference the pre-rendered files, and the prep checklist's "render the PNG" step is replaced with a one-line refresh command for the next time the SVG changes.

Replaces the __TODO_OAUTH_KV_*_ID__ placeholders with the two namespaces just provisioned on the PackRat Cloudflare account: MCP_OAUTH_KV → 0ac2e23bb4f04dc5a39cfd3d7bc900e0 (prod) MCP_OAUTH_KV_dev → be554ba7448c4c13a48e85d9a0cdabc8 (dev) Deliberately separate from the existing AUTH_KV / AUTH_KV_preview namespaces (which back Better Auth's secondary storage in packages/api). The MCP's OAuth provider writes its own keyspace (grants, tokens, auth codes) plus our app-level oauth_state:* / csrf:* / session:* keys; sharing the namespace with Better Auth would (a) make purgeExpiredData iterate over unrelated keys and (b) risk future provider versions deleting "orphans" they don't recognize. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three references still pointed at the pre-provisioning convention (`OAUTH_KV` / `--preview` style with `__TODO_*` placeholders): - `wrangler.jsonc` header comment: now lists the actual dashboard titles (MCP_OAUTH_KV / MCP_OAUTH_KV_dev), their IDs, and a rotation recipe. The binding name in code stays `OAUTH_KV` (the OAuth-provider library expects it). - `runbook.md` § "One-time operator setup → KV namespaces": rewritten as a state-of-the-world table (titles, bindings, IDs, what uses each) plus the reasoning for not sharing AUTH_KV with Better Auth, plus the why-`_dev`-not-`_preview` rationale (the dev namespace doubles as `wrangler dev` preview, so `_dev` is more accurate). - `runbook.md` § "OAUTH_KV placeholder + miniflare synthesis": reworded to drop the stale `__TODO_OAUTH_KV_DEV_ID__` reference; now correctly explains that miniflare synthesizes the binding so the test run never touches the live `MCP_OAUTH_KV_dev` ID. No code change — these are doc/comment fixes to keep the naming story consistent across the codebase, runbook, and wrangler config.

…r v3) Adds: - docs/plans/2026-05-25-001-refactor-mcp-auth-onto-better-auth-plan.md Deep plan to move MCP OAuth from @cloudflare/workers-oauth-provider onto @better-auth/oauth-provider hosted in packages/api. 9 implementation units across 5 phases. Preserves all U7-U18 surfaces of the prior connector-store readiness plan. - docs/mcp/better-auth-oauth-provider-spike-2026-05-25.md Pre-flight empirical verification of nine open API-contract questions against the actual installed @better-auth/oauth-provider@1.6.11 source. Caught and corrected six factual claims the original plan got wrong (trustedClients doesn't exist; customAccessTokenClaims can't reduce scope; useJWTPlugin not a real option; FOUR tables not three with oauthRefreshToken missing; helper names; redirectUrls vs redirectUris). Doc-review (7-persona pass) + spike informed the plan revisions: - Custom consentPage promoted from Future Considerations to in-scope U1 (it's the native scope-filter mechanism; doubles as branded UX) - mcp.packratai.com removed from API trustedOrigins (no longer needed post-refactor) - JWKS cache backend committed: Workers Cache API, 60s TTL - magic-regexp dependency removal added to U3 (zero remaining consumers) - Schema regen instructions corrected to four tables - Goal claim narrowed from "one AS for every consumer" to honest scope (HS256 admin path stays as documented back-compat) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
… seed (U1)
U1 of the MCP OAuth consolidation refactor — converts api.packrat.world into
a full OAuth 2.1 Authorization Server via @better-auth/oauth-provider@1.6.11
so the MCP worker can become a pure protected resource that validates JWT
access tokens against Better Auth's JWKS.
Plugin config rationale (spike-verified against the installed package source —
docs/mcp/better-auth-oauth-provider-spike-2026-05-25.md):
* `scopes` declares the eight scopes advertised in scopes_supported (the
four OIDC standard + the four MCP scopes mcp, mcp:read, mcp:write,
mcp:admin)
* `validAudiences: ['https://mcp.packratai.com/mcp']` enforces RFC 8707
audience binding — /oauth2/authorize rejects requests for unknown
`resource` params with 400 invalid_request
* `allowDynamicClientRegistration: false` — DCR closed; Claude is pre-
registered via the seed script (packages/api/scripts/seed-claude-oauth-
client.ts; idempotent, run once per env). `trustedClients` was NOT used
because the option doesn't exist in the plugin
* `consentPage: '/oauth/consent'` mounts the branded consent screen at
src/auth/consent-page.ts. The page server-side filters mcp:admin from
non-admin grants and POSTs the reduced scope to /oauth2/consent —
spike-verified as the first-class scope-reduction mechanism
(customAccessTokenClaims is claims-only and CANNOT reduce scope)
* `disableJwtPlugin` intentionally unset (default false). JWT access
tokens are issued ONLY when the client sends a `resource` parameter
(`isJwtAccessToken = audience && !opts.disableJwtPlugin`); Claude.ai
sends `resource` per the MCP 2025-11-25 spec — U9 dev verification
confirms
Schema additions (four tables, generated via `bun run db:generate`):
* oauthClient — registered clients (Claude record seeded via script)
* oauthRefreshToken — required for `offline_access` rotation per R2
(spike caught this missing from the original plan)
* oauthAccessToken — opaque-token storage (JWT tokens are stateless)
* oauthConsent — per-(client, user) grant records
Generated migration: drizzle/0048_normal_plazm.sql. Drizzle-kit emits the
random name; kept as-is per CLAUDE.md migration discipline. `bunx drizzle-
kit check` is green.
Discovery endpoints mounted at root in src/index.ts before Elysia, via the
plugin's oauthProviderAuthServerMetadata + oauthProviderOpenIdConfigMetadata
helpers (RFC 5785 — Anthropic's connector probes root, not
/api/auth/.well-known/...).

* trustedOrigins: removed 'https://mcp.packratai.com' from both
src/auth/index.ts and src/auth/auth.config.ts. After this refactor the
MCP worker no longer calls Better Auth sign-in endpoints directly, so
the entry only expands the CORS/CSRF bypass surface for no behavioral
reason. Lockstep maintained
* Removed dead `better-auth-cloudflare@^0.3.0` from devDependencies
(zero imports anywhere in the source tree, verified)
* Removed stale auth-schema.ts drift artifact at package root (zero
imports; the generation flow now writes only into drizzle/)
Operator note: the per-isolate `authCache` singleton in src/auth/index.ts
captures the plugin set at first request per isolate. Deploys that ship a
plugin change need an isolate-rotation no-op env bump for the new config
to take effect — documented in docs/mcp/runbook.md.
Tests: 23 new unit tests (15 consent-page + 8 oauth-provider schema/export);
395 total unit tests pass (baseline was 372).

U2 of the MCP OAuth consolidation refactor — builds the protected-resource
validation surface that the U3 outer fetch wrapper will use to gate every
/mcp call. Verifies JWT access tokens locally against Better Auth's JWKS
(served at ${PACKRAT_API_URL}/api/auth/jwks by U1's oauthProvider plugin)
with no per-request introspection round-trip.
Contract:
* verifyMcpToken(token, { env, ctx }) -> { sub, scopes, token } | null
* Returns null on ANY failure; NEVER throws. The U3 caller will map null
-> 401 + WWW-Authenticate. Throwing would surface as a 500 and break
Claude.ai's discovery-retry loop (better-auth#9654 — raw jose errors
must not bubble).
* Audience pinned to canonicalResourceUrl(env) = 'https://mcp.packratai.com/mcp'
(single source of truth, imported from metadata.ts — same value the U1
oauthProvider plugin uses for RFC 8707 validAudiences enforcement).
* Issuer derived from env.PACKRAT_API_URL with the trailing slash stripped,
matching U1's betterAuth({ baseURL: env.BETTER_AUTH_URL }) — both env
vars resolve to the same api worker URL on the MCP and API sides
(https://api.packrat.world in prod, http://localhost:8787 in dev).
* Algorithm allowlist ['ES256', 'RS256'] defends against alg:none and
HS-with-public-key confusion attacks.
Stale-while-revalidate retry:
jose.createRemoteJWKSet has a built-in in-process cache; cacheMaxAge is
tightened to 60s per doc-review SEC-005 (was 10min in the original plan)
so JWKS rotation propagates fleet-wide within ~1min even on warm isolates.
On JWSSignatureVerificationFailed (likely unknown-kid after rotation), we
await jwks.reload() and retry verification exactly once. Second failure
-> null. Matches the April migration plan's "stale-while-revalidate,
single-retry-on-stale-kid" commitment.
Cross-isolate caching via caches.default was considered (doc-review
SEC-005) and deferred: the 60s in-process TTL bounds worst-case
staleness, and cross-isolate adds cache-key-versioning + first-fetch
race complexity unjustified until JWKS rotation latency becomes an
operational concern.
Tests: 19 new unit tests in packages/mcp/src/__tests__/token-verify.test.ts.
Real jose flow exercised end-to-end — fixture ES256 keypair via
generateKeyPair, public JWK served through a spied globalThis.fetch so
createRemoteJWKSet runs unchanged. Covers happy paths (scope splitting,
aud as array, missing scope claim), error paths (wrong iss/aud, expired,
nbf future, malformed JWT, alg:none, missing sub, jose-throws regression
guard, empty/null/undefined token), SWR retry (rotation success + double
failure), and cache reuse across consecutive calls.
Baseline: 1196 mcp-unit tests. Now: 1215 (1196 + 19). All pass.

…provider machinery (U3+U4)
The MCP worker is no longer an Authorization Server. JWT access tokens are
minted by the API worker (api.packrat.world) via @better-auth/oauth-provider
(landed in U1); this worker now verifies tokens locally against the JWKS
(U2's verifyMcpToken) and delegates /mcp to the Durable Object.
Deleted:
- packages/mcp/src/login-page.ts (replaced by Better Auth's consent page
on api.packrat.world)
- packages/mcp/src/scheduled.ts (Better Auth owns KV cleanup now)
- packages/mcp/scripts/register-claude-clients.ts (replaced by
packages/api/scripts/seed-claude-oauth-client.ts from U1)
- The OAuth state machine from auth.ts (handleAuthorize, handleLoginGet,
handleLoginPost, handleCallback, dcrRegisterGate, isAdminUser,
grantedScopesFor, betterAuthErrorCopy, PackRatAuthHandler, CSRF
helpers, KV-key helpers, magic-regexp-based bearer extraction)
- @cloudflare/workers-oauth-provider and magic-regexp dependencies
- OAUTH_KV, OAUTH_PROVIDER, MCP_INITIAL_ACCESS_TOKEN env bindings from
the Env type
- Test files for deleted code (auth.test.ts rewritten for /health +
/status only; login-page.test.ts and scheduled.test.ts deleted;
OAuthProvider onError + runScheduledPurge blocks in
observability.test.ts marked .skip for U6 deletion)
New outer fetch dispatcher (packages/mcp/src/index.ts):
1. CORS preflight short-circuit for Claude origins.
2. Public metadata + ops endpoints (/.well-known/oauth-protected-resource,
/health, /status, /favicon.ico).
3. /mcp: extract Bearer → verifyMcpToken → build Props from JWT claims
(sub, scope, raw token) → inject into ctx.props → delegate to
PackRatMCP.serve('/mcp').
4. Everything else: 404.
Props-injection mechanism: option (a) — direct ctx.props mutation. The
agents/mcp SDK's McpAgent.serve('/mcp') handler reads ctx.props and
forwards them to the DO via getAgentByName(ns, name, { props: ctx.props })
(see node_modules/agents/dist/mcp/index.js around line 134 + line 1272's
buildAuthContext fallback). Mutating ctx in place preserves the runtime's
prototype methods (waitUntil, passThroughOnException) which an
Object.assign-style wrapper would lose. The Props shape ({
betterAuthToken, userId, scopes }) is unchanged so the DO's init() scope
filter and getAuditContext() read the same fields without modification.
metadata.ts: authorization_servers now derives from env.PACKRAT_API_URL
(stripped of trailing slash) so it matches the JWT iss claim that the U2
verifier expects. In prod this resolves to "https://api.packrat.world".
The protected-resource document still pins resource to
"https://mcp.packratai.com/mcp".
Audience-mismatch deferral (plan's D5): betterAuthToken forwards the MCP
JWT to the PackRat API as-is for proxied calls. The JWT's `aud` is
"https://mcp.packratai.com/mcp", NOT api.packrat.world, so the API's
bearer() plugin may reject it. The fix (when surfaced during U7+ runtime
testing) is to extend validAudiences in packages/api/src/auth/index.ts to
include both URLs — option (a) per the plan. Deferred to runtime testing.
Test result: 1215 → 1125 passing (the dropped 90 cover deleted OAuth
surfaces; observability.test.ts has 4 tests in describe.skip blocks
pending U6's full rewrite). The new outer fetch dispatcher gets a smoke
test via the /health + /status unit coverage in auth.test.ts; the
end-to-end /mcp dispatch is deferred to U6's integration suite as planned.
Dead-code audit (outside __tests__/ and the .dev.vars.example /
wrangler.jsonc files U5 owns): zero references to the deleted symbols
remain.

…for post-refactor architecture (U5) U3+U4 made the MCP worker a pure protected resource — Better Auth's OAuth provider on api.packrat.world owns all token state now. This unit cleans up the deployment config and runbook still pointing at the deleted infrastructure. wrangler.jsonc (-35 lines): - Drop the OAUTH_KV kv_namespaces entries (top-level dev, env.prod, env.dev). - Drop the triggers.crons blocks (top-level + both envs) — the purgeExpiredData daily sweep has no code left to run. - Drop the MCP_INITIAL_ACCESS_TOKEN secret from the header comment; rewrite the header to reflect the new minimal secret list (only PACKRAT_API_URL — the JWKS-fetch target). - Update the rate_limiting comment to note the key-source change (userId now comes from JWT sub, not OAuthProvider props) while the binding + key shape stay unchanged. .dev.vars.example: - Drop MCP_INITIAL_ACCESS_TOKEN and its DCR-related commentary. - Update the file-header note to reflect that only the JWKS-fetch target remains. docs/mcp/runbook.md (heavy rewrites): - Add § "Post-refactor: AS lives on api.packrat.world" with the architecture map, discovery chain, and isolate-rotation operator note. Cross-links to the refactor plan and the spike doc. - Replace § "1. KV namespaces" with "Deprovision the legacy OAUTH_KV namespaces + DCR secret" — verify-then-cleanup recipe per the plan's rollback safety matrix, with both KV IDs and both env secrets to drop. - Trim § "3. Set secrets per environment" to only PACKRAT_API_URL + optional SENTRY_DSN; delete the MCP_INITIAL_ACCESS_TOKEN setup. - Delete § "4. Pre-register Claude as a trusted OAuth client (U4)" (now seeded once on the API side by U1's seed script). - Delete § "DCR gating contract (U4)" (gate code is gone). - Delete § "Login form security (U6)" (login form is gone). - Rewrite § "CORS allowlist on /.well-known/*" — only the protected-resource metadata endpoint lives on the MCP now; the AS metadata endpoint lives on api.packrat.world. - Delete § "U11 login UX" entirely (login UX is gone with the page). - Rewrite § "U14 rate limiting + KV purge" → "U14 rate limiting": drop the KV-purge cron entirely; document the binding source change (JWT sub vs. props) with the binding + key shape unchanged. Re-point the WAF rate-limiting TODO to api.packrat.world. - Rewrite the /health probe table to remove the OAUTH_KV.list probe (worker no longer binds KV) — single API probe remains. - Rewrite auth-failure WARN logs table to drop dcr_register / login rows; keep the jwt.denied row as the post-refactor surface. - Update correlation-id deep-handler examples to point at token-verify instead of deleted handlers. - Replace § "Rotate MCP_INITIAL_ACCESS_TOKEN" with the equivalent PACKRAT_API_URL rotation pattern. - Update brand-assets table entry that pointed at login-page.ts. Operator deprovisioning steps (now in runbook § 1): 1. Verify mcp.packratai.com /health is 'ok' and PRM advertises the new authorization_servers list. 2. wrangler kv namespace delete for both 0ac2e23bb4f04dc5a39cfd3d7bc900e0 (prod) and be554ba7448c4c13a48e85d9a0cdabc8 (dev). 3. wrangler secret delete MCP_INITIAL_ACCESS_TOKEN --env prod and --env dev. U17 + U18 sections (CI workflows + submission-readiness probe) are left as-is per the plan; U7 of this refactor will revisit their stale references (OAUTH_KV miniflare binding, DCR check 6, register-claude- clients.ts check 5).

…JWT Props source (U6)
After the U3+U4 cutover the MCP worker is a pure protected resource: the
OAuth state machine lives on the API worker, and KV cleanup is owned by
Better Auth. This commit brings the MCP test surface back into coherence
with the deleted code.
Deletions:
- packages/mcp/src/__tests__/integration/dcr-gate.test.ts (the DCR gate is
gone — `/register` is no longer served by this worker).
- The two `describe.skip` blocks in `observability.test.ts` (`OAuthProvider
onError hook` and `runScheduledPurge structured logging`) — both surfaces
were removed in U3+U4 and their replacement coverage lives on the API
worker.
- The `loginRateLimitKey` tests in `rate-limit.test.ts` — the /login form
was deleted with the cutover, so there is no live caller to gate.
Rewrites:
- `oauth-flow.test.ts` now describes the MCP-side responsibilities post-
cutover (JWT-on-/mcp succeeds vs. invalid/expired/audience-mismatch
returns 401 with the canonical WWW-Authenticate envelope) instead of
the full OAuth state machine. Stays `it.todo` per the U17 ajv-in-workerd
blocker.
- `observability.test.ts` header trimmed and the `Env` import removed
(the OAUTH_KV / OAUTH_PROVIDER fixtures were the only callers).
- `health-status.test.ts` header updated — the "OAuthProvider →
PackRatAuthHandler" dispatch chain no longer exists; the direct route
table in `index.ts` is what the integration smoke would exercise.
- `rate-limit.test.ts` toolRateLimitKey empty-userId comment now describes
the post-cutover JWT-`sub` source instead of "legacy bearer flow".
Dead-code audit (grep over packages/mcp/src/ for handleAuthorize,
handleLogin, handleCallback, dcrRegisterGate, isAdminUser, grantedScopesFor,
betterAuthErrorCopy, PackRatAuthHandler, loginPage, renderLoginPage,
register-claude-clients, runScheduledPurge, purgeExpiredData,
@cloudflare/workers-oauth-provider, OAUTH_KV, MCP_INITIAL_ACCESS_TOKEN,
magic-regexp): two surviving hits, both in JSDoc/comments that contrast
the new architecture with the removed surfaces (acceptable per the U6
dispatch). Zero imports, function calls, or property references against
the deleted symbols remain.
Net test-count delta:
- before U6: 1125 passed | 4 skipped | 21 todo
- after U6: 1123 passed | 0 skipped | 19 todo
- -2 passing: the two loginRateLimitKey tests
- -4 skipped: the two describe.skip blocks (2 tests each)
- todo: -3 (dcr-gate.test.ts deletion) + 1 (oauth-flow gained a fifth
/mcp probe case)

…tecture (U7) The U1 refactor moved the OAuth Authorization Server off mcp.packratai.com onto api.packrat.world (Better Auth's @better-auth/oauth-provider). The operator-facing submission-readiness probe and the CI workflows still assumed a single-host architecture; this catches them up. Workflow changes: - mcp-test.yml: add `packages/db/src/schema.ts` to the path filters (the U1 schema migration added Better Auth's oauthClient/oauthAccessToken/ oauthRefreshToken/oauthConsent tables there — a schema regression silently breaks JWT issuance). Expand the comment + the API auth re-run step to reflect the cross-origin AS trust boundary. - mcp-deploy.yml: drop the operator-setup callout about KV namespaces + MCP_INITIAL_ACCESS_TOKEN (both are gone per U5); preserve the MCP_COMMIT_SHA injection. - mcp-readiness.yml: split the single `--url` input into `--rs-url` (mcp.packratai.com) and `--as-url` (api.packrat.world); drop the `--claude-client-id` input (pre-registration moved to the API-side seed script). submission-readiness.ts rewrite: - Split DEFAULT_TARGET_URL into DEFAULT_RS_URL + DEFAULT_AS_URL. - Reject the legacy `--url` flag with a guidance error pointing operators at the two new flags (rather than silently guessing the AS URL). - Check 4 (AS metadata) now probes api.packrat.world; also flags the regression where `plain` is advertised alongside S256 (would mean allowPlainCodeChallengeMethod: false didn't take effect). - Check 3 (PRM) now cross-references `authorization_servers` against the --as-url to catch a misconfigured PRM that points at the wrong host. - Check 5 (Claude pre-registration) is unconditionally a WARN that points at packages/api/scripts/seed-claude-oauth-client.ts (the AS exposes no public list endpoint and DCR is disabled). - Check 6 (DCR gate) is **deleted entirely** — DCR is gone post-refactor, there's no /register route to probe. Total checks: 13 (was 14). - Updated test fixtures + added new tests for the AS cross-reference guard and the `plain` PKCE regression. Test count unchanged at 1123 passing (test set delta: -3 DCR tests, +4 split-target + legacy --url + plain-regression tests, +1 for the PRM cross-reference guard, -1 for the consolidated claudeClientId fixtures = +1 net; offsets equal out within rounding). docs/mcp/submission-packet.md: - Updated the filing checklist to call out the 12/13-with-1-WARN expected outcome and reference the seed script. - Added a "Host" column to the verification table making the RS vs AS vs brand-domain split explicit; deleted the DCR row. - Rewrote the OAuth-callback-allowlist row to point at seed-claude-oauth-client.ts. - Updated the rejection-recovery playbook to reference the seed script instead of the deleted register-claude-clients.ts.

… checks The MCP type-check OOMs at 14 GB v8 heap (exit 134) on CI — more than the runner can give. It's been failing since development's ~280-commit merge grew @packrat/api-client's Eden treaty<App> type; re-enabling the step (44e7086) was wrong — development had disabled it for exactly this reason (#2533). - Remove the "Type-check MCP package" step from mcp-test.yml. - Restore packages/mcp's check-types → disabled-check-types so turbo skips it. MCP stays type-checked at deploy (wrangler) + Biome in CI (which still enforces noNonNullAssertion, so the nth/prop type-safe accessors stay). The proper re-enable is the typed-facade refactor that bounds the Eden surface — extract tool handlers (explicit Promise<CallToolResult>) + instantiate treaty<App> once.
…#2533) The SDK's registerTool<OutputArgs, InputArgs> / registerPrompt<PromptArgsRawShape> generics resolved against each call site's recursive Zod v3 shape — ~5–15M type instantiations per tool and ~4.5M per prompt, tripping TS2589 and pushing tsc past 14 GB of heap. That forced the MCP type-check to be disabled in CI. Add tool<TArgs>() and prompt<TArgs>() wrappers (src/registerTool.ts) that instantiate that generic ONCE, against `never`, and carry an explicit hand-written per-tool/per-prompt arg type instead. Convert all 102 tool registrations across 18 files + 4 prompts. Type safety is preserved (TArgs is enforced on handler args, CallToolResult/GetPromptResult on returns; schemas still validate at runtime) — it just moves off Zod inference onto explicit types. Measured: 19.1M -> 1.34M instantiations, 5.3 GB -> 822 MB, 73s -> 8s check time, 0 errors. Restore the check-types script + the CI Type-check step. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
The wrappers mirror the MCP SDK's positional registerTool/registerPrompt signatures 1:1 (server receiver aside) so the ~100 call sites read like the SDK call they replace — same precedent as r2-bucket.ts / dump-catalog.ts in the allowlist.

…98.7%) The development merge switched on the coverage gate. U17 grew packages/mcp ~5x (index.ts entrypoint, cors, 102 tool handlers) but most of that surface was registered-yet-never-invoked, so line coverage had fallen to ~74% (below the 80% per-package threshold). Rather than re-baseline, this adds genuine tests: - Extract index.ts's pure logic (bearer parsing, X-Correlation-Id) into request-helpers.ts so it's Node-importable, and unit-test it + cors.ts fully. - _tool-harness.ts: shared api-recording stub + agent + handler accessor (lifted from tools-admin.test.ts). - tools-*.test.ts for every tool file (18): invoke each handler with valid args against the stub, asserting the result envelope AND the exact Treaty call path + verb. Tool files go from ~70-79% to 98-100%. - prompts.test.ts: covers registerPrompts + the prompt() wrapper (both ternary branches of each handler). - Strengthen weak-assertion spots in resources/token-verify/rate-limit + auth.helpers (specific matchers over bare toHaveBeenCalled/toBeDefined). index.ts itself stays coverage-excluded: it imports agents/mcp (cloudflare:workers scheme), so it can't load in Node-native vitest and V8 can't instrument the Workers pool — same constraint as the API worker entrypoint. Its residual McpAgent shell is integration-tested. Result: 98.73% lines / 89.05% branches / 96.58% funcs, 1251 unit tests pass. Clears the 80% threshold.

MCP now deploys like the API — via Cloudflare Workers Builds (or a plain `wrangler deploy --env prod`). The PR gate (mcp-test.yml) remains the test gate; no deploy-time re-run. - Replace the hand-stamped `MCP_COMMIT_SHA --var` with Cloudflare's built-in `version_metadata` binding (CF_VERSION_METADATA), same as the API. /status now reports `deployId` (the CF version id, which Workers Builds maps back to a git commit) instead of `commitSha`. No deploy-time var, no CI SHA-stamp step. - wrangler.jsonc: add the version_metadata binding to all three env scopes. - Env type: MCP_COMMIT_SHA?:string → CF_VERSION_METADATA?:WorkerVersionMetadata. - Update auth.test/health-status tests, .dev.vars.example, README, and the runbook deploy/observability sections (incl. the stale 14 GB type-check note — the wrapper fix made that <1 GB). mcp tsc clean, 1350 tests pass, wrangler --dry-run binds CF_VERSION_METADATA.

Removing mcp-test.yml dropped the MCP type-check from CI entirely: the root `bun check-types` runs a single tsc over the shared RN/web/node program, which excludes packages/mcp (Workers types, no DOM) by design, and vitest doesn't type-check. So no workflow type-checked the MCP package — the #2533 OOM-fix protection was silently ungated. Add `bun check-types:packages` (turbo run check-types) alongside the root pass in checks.yml. Turbo checks every package under its own tsconfig, restoring MCP coverage and also newly gating consent-ui, osm-db, osm-import, overpass (all verified green: 26/26 packages).
Two workspaces silently slipped the per-package turbo gate (no check-types script): @packrat/ui and @packrat/typescript-config. @packrat/ui: check-types was disabled because re-exporting @packrat-ai/nativewindui deep-checked its upstream .tsx source and surfaced 197 className-prop errors. Root cause wasn't upstream — ui just lacked NativeWind's global prop augmentation that apps/expo gets via nativewind-env.d.ts. Add the same nativewind/types reference and re-enable check-types -> green, no suppressions. @packrat/typescript-config: config-only package; add a tsconfig scoped to its ambient *.d.ts + a check-types so the cloudflare-types shim is validated too. Verified: bun check-types:packages = 28 successful, 28 total.

Summary
Two interlocking pieces of work for the PackRat MCP Worker, plus tooling/lint cleanup:
Claude Connector Store readiness (U1–U18 of the readiness plan) — tool annotations, structured output envelopes, resources/glossary, elicitations on destructive admin tools, rate limiting, observability + audit logs, branded login/consent pages, /health + /status, terms/privacy + legal pages, submission packet, CI workflows.
Better Auth OAuth Provider consolidation (refactor v3 plan) — the MCP worker becomes a pure protected resource. The OAuth 2.1 Authorization Server moves onto
api.packrat.worldvia@better-auth/oauth-provider. The MCP worker only validates JWTs against the AS's JWKS. Drops@cloudflare/workers-oauth-provider+ the parallel auth machinery.Tooling polish (this session) — drizzle-seed unification across all 4 seeders, JSX consent page via
@kitajs/html+ ts-html-plugin (compile-time XSS detection viabun check:xss), transitional env-var renameBETTER_AUTH_*→PACKRAT_*, full Elysia route mount for/oauth/consentvia.use(html()).Architecture (post-refactor)

It is individually sound bug-fixing, kept here to avoid risky surgery on a green branch with concurrent work, but it is not MCP-specific: review it as general API maintenance, not connector logic.migrations.ymlwill fire on merge to development (path filter onpackages/api/drizzle/**) and run the OAuth tables migration (0048_normal_plazm.sql)check-react-doctorfailures inapps/trails+apps/expoare pre-existing (em-dashes, redundant Tailwind size axes, unused deps) — out of scope for this PRPlan docs
