Overview

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

This example deploys a remote Model Context Protocol (MCP) server on Cloudflare Workers without requiring authentication. It is designed for developers who want to expose MCP tools over the internet quickly, using Cloudflare’s serverless platform.

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

Deploy using the “Deploy to Workers” button to get a URL like remote-mcp-server-authless.<account>.workers.dev/sse, or run npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Customize tools by editing init() in src/index.ts with this.server.tool(...). Connect to Cloudflare AI Playground by entering the SSE URL, or to Claude Desktop by configuring a mcp-remote proxy in claude_desktop_config.json.

Frequently asked questions

What runtime does the server require?

It runs on Cloudflare Workers; local development uses npm and the `create cloudflare` CLI.

How do I add custom tools?

Define each tool inside the `init()` method of `src/index.ts` using `this.server.tool(...)`.

How can I connect to the Cloudflare AI Playground?

Go to https://playground.ai.cloudflare.com/ and enter your deployed SSE URL (`remote-mcp-server-authless.<account>.workers.dev/sse`).

How do I connect Claude Desktop to this server?

Use the `mcp-remote` npm package as a proxy. In Claude Desktop’s `claude_desktop_config.json`, set the command to `npx` with arguments `["mcp-remote", "<sse-url>"]`.

Does this server require authentication?

No, this example explicitly deploys an MCP server **without** authentication.
