Workers MCP Server

Example Use Cases

• 1

  Invoke Cloudflare Worker methods remotely (via MCP) to access Cloudflare bindings or third-party services through a secure RPC endpoint.

• 2

  Automatically generated, LLM-friendly documentation of available worker methods (from JSDoc) so tools/list returns rich method descriptions and parameter info.

• 3

  A local MCP proxy to translate tools/list and tools/call into authenticated fetch requests to a deployed worker, enabling integration with Claude Desktop.

Description

This repository demonstrates how to implement a Model Context Protocol (MCP) server using Cloudflare Workers so MCP clients can list and call worker methods. It includes a docs generator that extracts JSDoc from source to produce tools metadata, a public /rpc HTTP handler for the worker, and a local proxy that bridges MCP tools/list and tools/call to the deployed worker. The approach makes it easy to expose server-side capabilities (e.g., email routing, browser rendering) to Claude Desktop, but it is a proof-of-concept with several limitations and has been superseded by a newer package.
