Overview

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

This example lets you deploy a remote Model Context Protocol (MCP) server on Cloudflare Workers without authentication. It is aimed at developers who want to host MCP tools on Cloudflare’s edge network and connect them to compatible clients.

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 defining them inside the init() method of src/index.ts using this.server.tool(...). Connect from Cloudflare AI Playground by entering the deployed SSE URL, or from Claude Desktop via the mcp-remote proxy.
