This server lets you deploy a remote Model Context Protocol (MCP) server on Cloudflare Workers without requiring authentication. It is intended for developers who want to expose MCP tools over HTTP/SSE and connect them to remote or local MCP clients.

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

Deploy with one click using the "Deploy to Workers" button, or via npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless. The server URL will be remote-mcp-server-authless.<your-account>.workers.dev/sse. Customize tools by editing src/index.ts inside the init() method using this.server.tool(...).
