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 provides an SSE‑based endpoint that remote MCP clients (like Claude Desktop or the MCP Inspector) can connect to over the internet.

Clone the repository from github.com/cloudflare/ai, install dependencies with npm install, and run locally with npx nx dev remote-mcp-server. To deploy, create a KV namespace (npx wrangler kv namespace create OAUTH_KV) and run npm run deploy. Connect clients by pointing them to the Worker’s /sse URL (e.g., https://worker-name.account-name.workers.dev/sse).

Frequently asked questions

How do I run the server locally?

Clone the repo, `npm install`, then `npx nx dev remote-mcp-server`. The server will be available at `http://localhost:8787/`.

How do I connect Claude Desktop to the deployed server?

In Claude Desktop settings, add an MCP server entry with command `npx mcp-remote` and arguments pointing to the Worker’s `/sse` URL (e.g., `https://worker-name.account-name.workers.dev/sse`).

What transport does the server use?

It uses SSE (Server‑Sent Events) — set Transport Type to `SSE` and connect to the `/sse` path.

How do I debug connectivity issues?

Restart Claude, or test directly with `npx mcp-remote http://localhost:8787/sse`. If needed, clear cached auth files with `rm -rf ~/.mcp-auth`.
