Overview

What is Remote MCP Server on Cloudflare?

Remote MCP Server on Cloudflare provides a ready-to-deploy MCP (Model Context Protocol) server running on Cloudflare Workers, complete with OAuth login. It allows developers to host MCP tools remotely and connect them to MCP clients such as Claude Desktop or the MCP Inspector.

How to use Remote MCP Server on Cloudflare?

Clone the repository (git clone [email protected]:cloudflare/ai.git), install dependencies (npm install), and run locally with npx nx dev remote-mcp-server. To connect a client, use the SSE endpoint (e.g., http://localhost:8787/sse for local, or your deployed Workers URL). Deploy to Cloudflare by creating a KV namespace (npx wrangler kv namespace create OAUTH_KV), adding the ID to wrangler.jsonc, and running npm run deploy.

FAQ from Remote MCP Server on Cloudflare

How do I run the server locally?

Clone the repo, install dependencies, then run 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?

Run npx @modelcontextprotocol/inspector, switch the transport type to SSE, and enter http://localhost:8787/sse (or your deployed URL) as the server URL. A mock login screen will appear — use any email and password to log in.

How do I connect Claude Desktop to the server?

Add an entry to Claude Desktop’s configuration file with the mcp-remote command pointing to your server’s SSE endpoint. Example: "command": "npx", "args": ["mcp-remote", "http://localhost:8787/sse"]. Claude will open a browser for OAuth login.

How do I deploy the server to Cloudflare?

Create a KV namespace (npx wrangler kv namespace create OAUTH_KV), add its ID to wrangler.jsonc, then run npm run deploy. Your server will be live at worker-name.account-name.workers.dev/sse.

How can I debug connection issues?

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