Overview

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

This example allows you to deploy a remote MCP server that doesn’t require authentication on Cloudflare Workers. It is intended for developers who want to host MCP tools on a remote server accessible via SSE, without a full authentication system.

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

Deploy via the “Deploy to Workers” button or run npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Add custom tools in src/index.ts using this.server.tool(...). Connect clients such as Cloudflare AI Playground or Claude Desktop (via the mcp-remote proxy) to the deployed SSE URL.
