概要

What is Workers Mcp?

Workers Mcp is a package that connects Claude Desktop (or any MCP Client) to a Cloudflare Worker on your account. It provides both CLI tooling and in‑Worker logic to expose Worker RPC methods as MCP tools.

How to use Workers Mcp?

Install with npm install workers-mcp, then run npx workers-mcp help for instructions. Create a Worker with a WorkerEntrypoint that exports RPC methods documented with JSDoc. Add workers-mcp docgen src/index.ts to your deploy script, add a fetch handler that proxies events to your entrypoint using ProxyToSelf, generate a shared secret with workers-mcp secret generate, deploy with npm run deploy, and finally run workers-mcp install <alias> <url> to add the Worker to Claude Desktop.

Key features of Workers Mcp

Supports iterative development with redeploy

Use cases of Workers Mcp

Build custom Cloudflare Worker tools that Claude can invoke
Deploy and interact with Worker functions via natural language
Rapidly prototype and iterate on Worker endpoints with AI assistance
Extend Claude’s capabilities with your own serverless logic

よくある質問

How do I install Workers Mcp?

Install it via npm: `npm install workers-mcp`.

How do I set up authentication?

Use `npx workers-mcp secret generate` to generate a shared secret, then `npx workers-mcp secret upload` to add it to your deployed Worker. The fetch handler uses `SHARED_SECRET` for authentication.

How do I redeploy after changing my Worker code?

Run `npm run deploy` (which runs `workers-mcp docgen` and `wrangler deploy`). If you change method names, parameters, or add/remove methods, Claude will only see the updates after a restart.

What transport does Workers Mcp use?

Currently only `ProxySelf` is provided, which requires the Worker to be available on a public URL. `ProxyToServiceBinding` and `ProxyToDurableObject` are planned.

Can I use an existing Worker?

Yes, as long as you route your `fetch` calls appropriately and define a `WorkerEntrypoint` with RPC methods.
