Overview

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

This example deploys a remote MCP (Model Context Protocol) server on Cloudflare Workers without requiring authentication. It is intended for developers who want a quick, public MCP server that can be used with remote MCP clients like Cloudflare AI Playground or local clients via a proxy.

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

Deploy by clicking the "Deploy to Workers" button or running npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Customize tools by editing the init() method in src/index.ts using this.server.tool(...). Connect via the Cloudflare AI Playground by entering the deployed SSE URL, or via Claude Desktop using the mcp-remote proxy and a JSON configuration.

Key features of Building a Remote MCP Server on Cloudflare (Without Auth)

Frequently asked questions

What dependencies do I need to run this?

You need Node.js and npm (or a Cloudflare account for the one-click deploy). The template includes Cloudflare Workers dependencies.

How do I add my own tools?

Define each tool inside the `init()` method of `src/index.ts` using `this.server.tool(...)`. See the Cloudflare MCP tools documentation for details.

How do I connect Claude Desktop to this remote server?

Use the `mcp-remote` npm package. Add an entry to Claude Desktop's MCP configuration with the command `npx mcp-remote <your SSE URL>`.

Where does the server data live?

The MCP server runs on Cloudflare Workers (edge network). No data persistence is described in the README; tools handle their own state.

What transport and authentication does it use?

It uses SSE transport and explicitly does **not** require authentication. The server is publicly accessible via its Workers URL.
