Overview

What is Remote MCP Server on Cloudflare?

A starter project to deploy a remote MCP (Model Context Protocol) server on Cloudflare Workers with OAuth login. It is intended for developers who want to expose MCP tools over the internet and connect them to clients like Claude Desktop.

How to use Remote MCP Server on Cloudflare?

Clone the repository, install dependencies with npm install, and run locally via npx nx dev remote-mcp-server. To deploy, create a KV namespace with npx wrangler kv namespace create OAUTH_KV, add the namespace ID to wrangler.jsonc, and run npm run deploy. Connect clients by pointing them to the server’s /sse endpoint using the MCP Inspector or by configuring Claude Desktop with the mcp-remote proxy command.

Frequently asked questions

How do I connect Claude Desktop to the server?

Edit Claude Desktop’s config file to add an `mcpServers` entry that uses `npx mcp-remote` with the server’s SSE URL (e.g., `http://localhost:8787/sse` for local, or the `workers.dev` URL for remote). Restart Claude to see the tools.

What transport does the server use?

The server uses SSE (Server-Sent Events) and is accessed via its `/sse` endpoint.

How do I debug connection issues?

Restart Claude, or try connecting directly from the command line with `npx mcp-remote http://localhost:8787/sse`. In rare cases, clear the files in `~/.mcp-auth` with `rm -rf ~/.mcp-auth`.
