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

This server allows you to deploy a remote MCP server that does not require authentication on Cloudflare Workers. It is intended for developers who want to expose MCP tools over SSE without adding authentication.

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

Deploy using the Cloudflare Deploy to Workers button or run npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless from the command line. After deployment, the server is available at a URL like remote-mcp-server-authless.<your-account>.workers.dev/sse. Customize tools by editing src/index.ts inside the init() method using this.server.tool(...).
