Overview

What is Remote MCP Server on Cloudflare?

Remote MCP Server on Cloudflare is a template for deploying a Model Context Protocol (MCP) server on Cloudflare Workers with OAuth login. It lets you run MCP tools remotely and connect clients like Claude Desktop or the MCP Inspector over SSE.

How to use Remote MCP Server on Cloudflare?

Clone the repository, install dependencies with npm install, and run locally with npx nx dev remote-mcp-server. Deploy to Cloudflare by creating a KV namespace (npx wrangler kv namespace create OAUTH_KV), adding its ID to wrangler.jsonc, then running npm run deploy. Connect clients using npx mcp-remote <url>/sse or configure Claude Desktop’s config with the mcp-remote command pointing to your server’s SSE endpoint.

FAQ from Remote MCP Server on Cloudflare

How do I run the server locally?

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

How do I connect the MCP Inspector to my server?

Start the inspector with npx @modelcontextprotocol/inspector, set Transport Type to SSE, enter http://localhost:8787/sse (or your remote URL), and click Connect. Complete the OAuth login to see and call tools.

How do I connect Claude Desktop to the server?

Edit Claude Desktop’s config file (Settings > Developer > Edit Config) and add an entry with command: "npx", args: ["mcp-remote", "http://localhost:8787/sse"] (or your remote URL). Restart Claude; a browser will open for OAuth login.

How do I deploy to Cloudflare?
