Overview
What is Remote MCP Server on Cloudflare?
Remote MCP Server on Cloudflare is a reference implementation for running an MCP (Model Context Protocol) server on Cloudflare Workers with OAuth login. It enables developers to expose MCP tools over HTTP/SSE and connect them to remote clients such as Claude Desktop.
How to use Remote MCP Server on Cloudflare?
Clone the repository, install dependencies with npm install, then run locally with npx nx dev remote-mcp-server. For deployment, create a KV namespace with npx wrangler kv namespace create OAUTH_KV, add its ID to wrangler.jsonc, and run npm run deploy. Connect clients via SSE by pointing them to http://localhost:8787/sse (local) or https://worker-name.account-name.workers.dev/sse (deployed). Use the MCP Inspector or mcp-remote proxy to interact with the server.

Frequently asked questions
How do I connect the MCP Inspector to my server?
Start the Inspector with `npx @modelcontextprotocol/inspector`, set Transport Type to SSE, and enter `http://localhost:8787/sse` (local) or the `workers.dev` URL as the server URL. A mock login screen will appear.
How do I connect Claude Desktop to the remote server?
Add an entry to Claude Desktop’s config file with `"command": "npx"` and `"args": ["mcp-remote", "http://localhost:8787/sse"]` for local or `"https://worker-name.account-name.workers.dev/sse"` for remote. Restart Claude and a browser login window will open.
How can I debug connection issues?
Run `npx mcp-remote http://localhost:8787/sse` directly on the command line. If needed, clear cached authorization files with `rm -rf ~/.mcp-auth`.
Does the server store any data? Where?
Yes, authentication state is stored in a Cloudflare KV namespace named `OAUTH_KV`, which you create during setup.
