Cloudflare Remote MCP Server

Example Use Cases

• 1

  Expose custom RPC-style tools (e.g., a math tool) to LLM clients over the MCP/SSE transport so the model can invoke external functionality.

• 2

  A deployable OAuth-enabled MCP endpoint on Cloudflare Workers to allow remote MCP clients like Claude Desktop to authenticate and call tools.

• 3

  A local development and debugging workflow (with MCP Inspector and local proxy) to iterate on tool definitions before deploying to production.

Description

This project sets up a remote Model Context Protocol (MCP) server running on Cloudflare Workers, with local development support and an OAuth-based mock login flow. It demonstrates how to connect MCP clients (MCP Inspector, Claude Desktop) over SSE and includes deployment instructions using Wrangler and KV for OAuth storage. The repository is useful for exposing custom tools (for example, math tools) to LLM-driven clients and testing integrations locally before deploying to a workers.dev endpoint.
