You can deploy a remote MCP server on Cloudflare Workers that serves tools to MCP clients without requiring authentication. This setup lets you connect from the Cloudflare AI Playground or from local MCP clients through a remote endpoint, enabling practical experimentation and quick tool access.

How to use

Connect your MCP client to the remote server to access its tools. You can use the Cloudflare AI Playground to run the MCP tools directly in your browser by pointing it at your deployed server URL. You can also connect from local MCP clients using the mcp-remote proxy by configuring your client to reach the server’s SSE endpoint. From Claude Desktop, you can import the remote server configuration so that tools appear in your local environment without hosting the server locally.

How to install

Prerequisites: you need Node.js and npm installed on your machine.

Install and bootstrap the remote MCP server using the Cloudflare template (executes in your shell):

npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless

Additional setup and usage notes

Customize your MCP server by editing the init logic to add tools. Open the project’s source and define each tool inside the init() method of src/index.ts using this.server.tool(...). This is how you expose new capabilities to MCP clients.
