Overview
What is Remote MCP Server on Cloudflare?
Remote MCP Server on Cloudflare is a reference implementation that runs a Model Context Protocol (MCP) server on Cloudflare Workers with OAuth login. It allows developers to deploy MCP tools remotely and connect clients like Claude Desktop over HTTP/SSE.
How to use Remote MCP Server on Cloudflare?
Clone the repository, install dependencies with npm install, and run locally using npx nx dev remote-mcp-server. Connect the MCP Inspector by switching transport to SSE and entering http://localhost:8787/sse. For Claude Desktop, configure it with the mcp-remote proxy pointing to the same SSE URL. Deploy to Cloudflare Workers by creating a KV namespace, adding its ID to wrangler.jsonc, and running npm run deploy.

How do I deploy the server to Cloudflare?
Create a KV namespace with npx wrangler kv namespace create OAUTH_KV, add the namespace ID to wrangler.jsonc, then run npm run deploy.
How can I debug connection issues?
Restart Claude, try connecting directly with npx mcp-remote http://localhost:8787/sse, or clear the files in ~/.mcp-auth with rm -rf ~/.mcp-auth.
