Overview

What is Remote MCP Server on Cloudflare?

This server runs a Model Context Protocol (MCP) server on Cloudflare Workers, complete with OAuth login. It is intended for developers who want to deploy a remote MCP server accessible from any MCP client.

How to use Remote MCP Server on Cloudflare?

Clone the repository, install dependencies, and run npx nx dev remote-mcp-server for local development. For remote deployment, create an OAUTH_KV namespace, add its ID to wrangler.jsonc, and run npm run deploy. Connect clients (e.g., MCP Inspector or Claude Desktop) using the SSE endpoint at http://localhost:8787/sse locally or your workers.dev URL after deployment.

Key features of Remote MCP Server on Cloudflare

  • Deployable on Cloudflare Workers with OAuth authentication.
  • Uses Server-Sent Events (SSE) transport.
  • Testable locally before deployment.
  • Supports MCP Inspector for tool discovery and calls.
  • Connects to Claude Desktop via a remote proxy (npx mcp-remote).
  • Provides a global workers.dev URL for client access.

Use cases of Remote MCP Server on Cloudflare

  • Deploy a remote MCP server reachable from any internet-connected client.
  • Give AI assistants like Claude access to custom tools over the web.
  • Authenticate users with OAuth before allowing tool execution.
  • Develop and test MCP tools locally, then deploy globally with minimal friction.

Frequently asked questions

1

How do I run this server locally?

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

2

How do I connect the MCP Inspector?

Start the inspector with `npx @modelcontextprotocol/inspector`, set Transport Type to `SSE`, and enter `http://localhost:8787/sse` (or your deployed URL) as the server URL. You will go through a mock OAuth login to connect.

3

How do I deploy the server to Cloudflare?

First create a KV namespace with `npx wrangler kv namespace create OAUTH_KV`, add the returned ID to `wrangler.jsonc`, then run `npm run deploy`.

4

How do I connect Claude Desktop to my deployed server?

Edit Claude Desktop’s config file to add an entry using `npx mcp-remote` pointing to your workers.dev/sse URL (e.g., `https://worker-name.account-name.workers.dev/sse`). Restart Claude; a login window will open.

5

What should I do if something goes wrong?

Try restarting Claude, or connect directly using `npx mcp-remote http://localhost:8787/sse`. In rare cases, clearing `~/.mcp-auth` with `rm -rf ~/.mcp-auth` may help.
