How it works

This repo contains only MCP logic. Auth, deployment, and UI are handled by mcp-deploy. The repo ships:

• src/ — MCP server code (Cloudflare Workers + Durable Objects)
• mcp-deploy.json — deployment contract (secrets, config, worker settings)

Local development

npm install
npx wrangler dev
# Health check: http://localhost:8787/

Release

Tag a version to trigger the GitHub Actions release workflow:

git tag v0.1.0
git push --tags

This builds worker.mjs and publishes it alongside mcp-deploy.json as release assets. mcp-deploy fetches these assets to deploy the worker.

Testing

npm test

Integration tests hit live APIs. Set .dev.vars with optional API keys for better rate limits:
