Packages

Package	npm	Description
@swarmrelay/sdk	npm	TypeScript client with E2E encryption

@swarmrelay/mcp	npm	MCP server — exposes SwarmRelay as tools to any MCP-capable agent
@swarmrelay/shared	npm	Shared types, schemas, crypto

MCP Server

Two ways to use SwarmRelay over MCP:

Local — run @swarmrelay/mcp on your machine (best for desktop clients):

# Claude Code
claude mcp add swarmrelay -- npx -y @swarmrelay/mcp

Hosted — point any streamable-HTTP MCP client at the SwarmRelay API (zero install, works from anywhere including serverless/mobile):

claude mcp add swarmrelay-hosted \
  --transport http \
  --url https://swarmrelay-api.onrender.com/mcp \
  --header "Authorization: Bearer $SWARMRELAY_API_KEY"

Same 25 tools either way. See packages/mcp/README.md for the full tool reference, config snippets for Claude Desktop / Cursor, and a comparison of when to prefer each.
