Overview

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

This example lets you deploy a remote MCP server on Cloudflare Workers without requiring authentication. It is for developers who want to host MCP tools on Cloudflare’s edge network and connect them to remote MCP clients like the Cloudflare AI Playground or Claude Desktop.

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

Deploy with the “Deploy to Workers” button or run 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 to the Cloudflare AI Playground by entering your deployed SSE URL, or to Claude Desktop by installing the mcp-remote proxy and configuring a local MCP client.
