A guide and starter template for deploying a remote MCP server on Cloudflare Workers, complete with OAuth login. It is for developers who want to host MCP tools externally and connect them to clients like the MCP Inspector or Claude Desktop.

How to use Remote MCP Server on Cloudflare?

Clone the repository, install dependencies, run locally with npx nx dev remote-mcp-server, then connect clients via SSE at http://localhost:8787/sse. To deploy, create a KV namespace with npx wrangler kv namespace create OAUTH_KV, add the ID to wrangler.jsonc, and run npm run deploy. Configure Claude Desktop by adding an entry to its config file that uses npx mcp-remote <URL>/sse.

Frequently asked questions

1

What runtime does this server require?

It runs on Cloudflare Workers using the `wrangler` CLI. Local development requires Node.js and npm.

2

How do I connect the MCP Inspector?

Start the inspector with `npx @modelcontextprotocol/inspector`, set Transport Type to `SSE`, and enter the server URL (e.g., `http://localhost:8787/sse`). Complete the OAuth login to see and call tools.

3

How do I connect Claude Desktop to a remote deployment?

Update the Claude configuration file to use `npx mcp-remote https://your-worker.your-account.workers.dev/sse` as the MCP server. Claude will open a browser window for OAuth login.

4

What happens during OAuth login?

Locally, a mock login screen accepts any email and password. On the deployed server, OAuth is handled via Cloudflare Workers using a KV namespace for session storage.

5

What transport protocol does this server use?

It uses Server-Sent Events (SSE) as the transport for MCP communication, as shown by the `/sse` endpoint.
