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 that requires no authentication. It is intended for developers who want to host MCP tools in a serverless environment and connect them to MCP clients like Cloudflare AI Playground or Claude Desktop.

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

Deploy by clicking the "Deploy to Workers" button or by running npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Customize tools inside the init() method of src/index.ts using this.server.tool(...). Connect to Cloudflare AI Playground or local clients via the mcp-remote proxy.

Frequently asked questions

1

What dependencies or runtime are required?

The server runs on Cloudflare Workers. Local development requires Node.js and npm. No additional authentication dependencies.

2

How do I add custom tools?

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

3

How do I connect to Cloudflare AI Playground?

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

4

How do I connect to Claude Desktop?

Use the `mcp-remote` proxy. In the Claude Desktop config, set the command to `npx mcp-remote <your-mcp-server-url/sse>`.

5

What transport does this server use?

It uses SSE (Server-Sent Events) at the `/sse` endpoint.
