Porta
- A secure MCP bridge for Almide-compiled WASM agents.
- The gate between the sandbox and the world.
+ Sandboxed runtime for AI agents and native commands.
+ WASM isolation for agents. OS-level sandbox for everything else.
- Written in Almide with a built-in WASM interpreter. No external runtime dependency.
+ Almide + Wasmtime · No Docker required
---
## What is Porta?
-Porta loads an Almide-compiled `.wasm` binary and exposes it as an MCP server over JSON-RPC 2.0 / stdio. It includes a built-in WASM interpreter — no wasmtime, wasmer, or other external runtime needed.
+Porta is a sandboxed runtime that controls what programs can access — filesystem, network, commands — using capability-based security.
-## Install
+Two execution modes:
+- **WASM sandbox** — Almide/Rust/C agents compiled to WASM run inside wasmtime with mathematical isolation
+- **Native sandbox** — Any command (Claude Code, Python, Node.js) runs inside an OS-level sandbox (macOS sandbox-exec, Linux namespaces)
+
+## Quick Start
+
+### Run Claude Code in a sandbox
```bash
-# From source (requires Almide >= 0.12.0)
-almide build
-cp porta ~/.local/bin/
+porta init native claude
+porta up -- --print "Fix the bug in main.rs"
```
-## Quick Start
+This creates a `porta.toml` and runs Claude Code with:
+- Filesystem writes restricted to the current directory
+- Sensitive directories (~/.ssh, ~/.aws, ~/Documents) unreadable
+- Network limited to HTTPS only
-```bash
-# Run a WASM agent
-porta run agent.wasm
+### Run a WASM agent
-# Start as MCP server (for Claude Code, Cursor, etc.)
-porta serve agent.wasm
+```bash
+porta run agent.wasm --profile full -v ./workspace
+porta serve agent.wasm # Start as MCP server
+```
-# Generate manifest from WASM binary
-porta build agent.wasm
+### Run Python in WASM sandbox
-# Inspect module info
-porta inspect agent.wasm
+```bash
+porta run python.wasm --env PYTHONHOME=/path/to/lib -v /path/to/lib -- script.py
```
-## Architecture
+## porta.toml
+
+Declarative configuration for sandboxed execution.
+
+```toml
+[runtime]
+type = "native" # "native" or "wasm"
+command = "claude" # Command to run (native mode)
+# wasm = "agent.wasm" # WASM binary (wasm mode)
+[sandbox]
+mounts = ["."] # Directories the command can write to
+# mounts = [".:ro"] # Read-only mount
+network = ["*:443"] # Allowed outbound ports (empty = allow all)
+
+[env]
+NODE_ENV = "production"
+
+[secrets]
+# API_KEY = "sk-..."

## Security Model
-Porta uses a **capability-based, deny-by-default** security model. All WASI access requires explicit capability grants.
+### Native Sandbox (macOS)
+
+Uses `sandbox-exec` to enforce:
-### Capability Profiles
+| Control | Behavior |
+|---------|----------|
+| **FS write** | Denied everywhere except `-v` mounted dirs |
+| **FS read** | `~/.ssh`, `~/.aws`, `~/.gnupg`, `~/Documents`, `~/Desktop`, `~/Downloads` denied |
+| **Network** | `--allow-net "*:443"` → HTTPS only. No flag = allow all |
+| **Read-only** | `-v ./data:ro` → read OK, write denied |
-| Profile | Grants |
-|---------|--------|
-| `ai-agent` | IO, Process (minimal for MCP tool dispatch) |
-| `worker` | IO, Process, Clock, Random |
-| `full` | All capabilities |
+### WASM Sandbox
-### 8 Capability Types
+Deny-by-default capability system:
-`io`, `fs`, `fs.write`, `process`, `env`, `clock`, `random`, `net`
+| Capability | Controls |
+|------------|----------|
+| `io` | stdin/stdout/stderr |
+| `fs` | File read (path_open, stat, readdir) |
+| `fs.write` | File write (create, rename, delete) |
+| `process` | Process lifecycle, args |
+| `env` | Environment variables |
+| `clock` | Time/clock |
+| `random` | Random bytes |
+| `net` | Network access |
+| `exec` | Command execution |
-### Enforcement
+Built-in profiles: `ai-agent` (IO + Process), `worker` (+Clock +Random), `full` (all).
-1. **Import validation** — WASI imports checked against capabilities at module load
-2. **Runtime check** — Every WASI call verified before execution
+## MCP Server
-### Three-Layer Defense
+```bash
+porta serve agent.wasm --profile full
+```
-1. **Compiler** (Layer 1) — Almide rejects capability violations at compile time
-2. **Binary** (Layer 2) — Disallowed WASI imports are absent from `.wasm`
-3. **Porta** (Layer 3) — Runtime enforcement: fd table, preopen dirs, env filtering, memory limits, step limits
+### Built-in Tools
-## Manifest Format
+| Tool | Description |
+|------|-------------|
+| `porta.exec` | Execute shell commands (sandboxed) |
+| `porta.http` | Make HTTP requests |
+| Agent tools | Dispatched to WASM agent |
+
+### Supported MCP Methods
+
+`initialize`, `tools/list`, `tools/call`, `resources/list`, `resources/read`, `prompts/list`, `prompts/get`, `ping`
+

+# Full Almide Migration
+
+Move non-wasmtime Rust code from `native/wasmtime_bridge.rs` to pure Almide. Reduce Rust surface area to wasmtime API calls only.
+
+## Currently in Rust (can move to Almide)
+
+| Function | Lines | Migration path |
+|----------|-------|----------------|
+| `wt_http_request` | ~40 | Almide HTTP stdlib (when available) |
+| `wt_exec_command` | ~25 | `process.exec(cmd, args)` |
+| `wt_exec_sandboxed` | ~80 | `process.exec("sandbox-exec", ["-p", profile, ...])` |
+| `wt_home_dir` | ~3 | `process.exec("sh", ["-c", "echo $HOME"])` |
+| `wt_spawn` | ~15 | Needs Almide process spawn support |
+| `wt_kill` | ~8 | Needs Almide signal support |
+
+## Must stay in Rust (wasmtime API)
+
+| Function | Reason |
+|----------|--------|
+| `wt_create` | Engine, Module, compilation cache |
+| `wt_run` | Store, Linker, WASI context, host function injection |
+| `wt_set_*` / `wt_get_*` | Instance pool mutation |
+| `wt_inspect` | Module import/export reflection |
+| `wt_destroy` | Instance cleanup |
+| linker host functions | `porta.http_request`, `porta.exec_command` in wasmtime |
+
+## Prerequisites
+
+- Almide HTTP stdlib module (for `wt_http_request` migration)
+- Almide process spawn without wait (for `wt_spawn`)
+- Almide signal sending (for `wt_kill`)
+
+## Goal
+
+`native/wasmtime_bridge.rs` should contain ONLY wasmtime API calls (~200 lines). Everything else in Almide.
