Overview

What is Remote MCP Server on Cloudflare?

A reference implementation for deploying a remote MCP (Model Context Protocol) server on Cloudflare Workers with OAuth login. It is designed for developers who want to host MCP tools remotely and connect them to clients like Anthropic’s Claude Desktop.

How to use Remote MCP Server on Cloudflare?

Clone the repository, install dependencies with npm install, and run locally with npx nx dev remote-mcp-server. Use the MCP Inspector by connecting over SSE to http://localhost:8787/sse with npx @modelcontextprotocol/inspector. Deploy to Cloudflare by running npm run deploy after configuring a KV namespace for OAuth. For production, configure Claude Desktop’s claude_desktop_config.json with the mcp-remote command pointing to your deployed workers.dev/sse URL.

Frequently asked questions

What is the MCP server, and how is it different from a standard server?

It is a Model Context Protocol server that runs on Cloudflare Workers, adding remote access and OAuth login compared to a local MCP server.

What dependencies do I need to run it locally?

Node.js and npm. The project is part of a monorepo and uses Nx for development commands.

Where does authentication data live?

In a Cloudflare KV namespace called `OAUTH_KV` that you create with `npx wrangler kv namespace create OAUTH_KV` and reference in `wrangler.jsonc`.

What transport protocol does the server use?

SSE (Server-Sent Events) over HTTP. Client connections are made to the `/sse` endpoint.

Are there known limits for the deployed server?

The README does not specify limits, but deployment requires a Cloudflare Workers account and may be subject to Workers plan quotas.
