Remote MCP Server (Authless)

You deploy a remote MCP Server on Cloudflare Workers that serves your MCP tools without requiring authentication. It lets you expose your MCP tools to clients like the Cloudflare AI Playground or Claude Desktop, enabling you to run and test tools from anywhere with a simple, scalable URL.

How to use

Connect from an MCP client to your remote server using the provided remote URL or through a local proxy. In the Cloudflare AI Playground, enter your deployed MCP server URL to access and run your tools directly from the playground. If you prefer a local client setup, use the mcp-remote proxy with the URL of your remote server to expose the tools locally.

How to install

Prerequisites: you need Node.js and npm installed on your machine. Ensure you have access to a Cloudflare account for deploying Workers.

# Step 1: Create the MCP server project using the remote-authless template
npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless

# Step 2: Navigate into the project and install dependencies
cd my-mcp-server
npm install

# Step 3: Deploy your MCP server to Cloudflare Workers
npm run deploy

# Step 4: Note the deployed URL; your server will be reachable at a URL like:
# remote-mcp-server-authless.<your-account>.workers.dev/sse

Additional notes

Two common ways to connect to your remote MCP server are provided below. The first is a public, remote URL you deploy on Cloudflare Workers. The second is a local proxy configuration you can use with a local client like Claude Desktop to access the remote server.
