Overview

What is Building a Remote MCP Server on Cloudflare (Without Auth)?

A deployable template that lets you create a remote MCP (Model Context Protocol) server on Cloudflare Workers without requiring authentication. It is intended for developers who want to expose MCP tools remotely and connect them to clients like Cloudflare AI Playground or Claude Desktop.

How to use Building a Remote MCP Server on Cloudflare (Without Auth)?

Deploy the server either by clicking the "Deploy to Workers" button or by running npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless in the command line. After deployment, customize tools inside the init() method of src/index.ts using this.server.tool(...). Connect to Cloudflare AI Playground by entering the deployed SSE URL, or to Claude Desktop by using the mcp-remote proxy with the same URL.

Frequently asked questions

What are the prerequisites to deploy this server?

A Cloudflare account and Node.js/npm are required to deploy using the template.

How do I add my own tools to the MCP server?

Each tool is defined inside the `init()` method of `src/index.ts` using `this.server.tool(...)`. The server’s tools section in the Cloudflare documentation provides more details.

How can I connect this server to Claude Desktop?

Install the `mcp-remote` npm package and configure Claude Desktop’s `mcpServers` to use `npx mcp-remote <your-server-sse-url>`.

Where does the MCP server data live?

The server runs on Cloudflare Workers; tool definitions are stored in your code, and any runtime data persists only within the worker’s execution context.

What transport does this server use?

This server uses the SSE (Server-Sent Events) transport protocol.
