Overview

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

Building a Remote MCP Server on Cloudflare (Without Auth) is an example project that allows you to deploy a remote MCP server on Cloudflare Workers without requiring authentication. It is intended for developers who want to expose MCP tools remotely via SSE and connect them to MCP clients such as the Cloudflare AI Playground or Claude Desktop.

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

Deploy using the "Deploy to Workers" button or run npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless locally. Customize the server by adding tools inside the init() method of src/index.ts using this.server.tool(...). Connect to the Cloudflare AI Playground by entering the deployed URL (e.g., remote-mcp-server-authless.<your-account>.workers.dev/sse). To connect from Claude Desktop, use the mcp-remote proxy in your Claude Desktop configuration.

Key features of Building a Remote MCP Server on Cloudflare (Without Auth)

  • Deploy a remote MCP server without authentication.
  • Hosted on Cloudflare Workers via SSE endpoint.
  • Easily customizable with custom tools in src/index.ts.
  • Connect directly from the Cloudflare AI Playground.
  • Works with local MCP clients via the mcp-remote proxy.
