Overview

What is Remote MCP Server on Cloudflare?

A template for hosting a remote MCP (Model Context Protocol) server on Cloudflare Workers, complete with OAuth login. It is intended for developers who want to run MCP tools on a serverless platform and connect them to AI clients like Claude Desktop.

How to use Remote MCP Server on Cloudflare?

Clone the repository, install dependencies, and run npx nx dev remote-mcp-server for local development. Deploy by creating a KV namespace with npx wrangler kv namespace create OAUTH_KV, adding the namespace ID to wrangler.jsonc, and running npm run deploy. Connect clients (MCP Inspector or Claude Desktop) via SSE at the server’s /sse endpoint.

Frequently asked questions

1

How do I run the server locally?

Clone the repo, run `npx nx dev remote-mcp-server` in the `ai` directory, then open `http://localhost:8787/` in a browser.

2

How do I connect the MCP Inspector to my local server?

Start the inspector with `npx @modelcontextprotocol/inspector`, set Transport Type to `SSE` and URL to `http://localhost:8787/sse`, then click “Connect”. You will be prompted to log in (any email/password works in the mock flow).

3

How do I deploy the server to Cloudflare?

Create a KV namespace with `npx wrangler kv namespace create OAUTH_KV`, paste the returned ID into your `wrangler.jsonc` file, then run `npm run deploy`.

4

How do I connect Claude Desktop to a remote instance?

Update your Claude Desktop config file to use the `mcp-remote` command and point it to your `workers.dev` URL (e.g., `https://worker-name.account-name.workers.dev/sse`). Restart Claude; a browser window will open for login.

5

How can I debug connection issues?

Try connecting directly from the command line with `npx mcp-remote http://localhost:8787/sse`. In rare cases, clearing the `~/.mcp-auth` folder can resolve authentication problems. Restarting Claude may also help.
