Overview
What is Building a Remote MCP Server on Cloudflare (Without Auth)?
This example allows you to deploy a remote MCP server on Cloudflare Workers that does not require authentication. It is for developers who want to run MCP tools at the edge and connect them to remote MCP clients like 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 via npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. Customize tools by defining each inside the init() method of src/index.ts using this.server.tool(...). Connect to Cloudflare AI Playground by entering the deployed SSE URL, or connect to Claude Desktop using the mcp-remote proxy configured in the Claude Desktop settings.
