常见问题

Does this server require any authentication?

No, the server is specifically designed to not require authentication. It is “authless.”

How do I deploy this MCP server?

You can deploy it instantly using the “Deploy to Workers” button in the README, or by running `npm create cloudflare@latest -- my-mcp-server --template=cloudflare/ai/demos/remote-mcp-authless` locally.

How can I add custom tools to the server?

Define each tool inside the `init()` method of `src/index.ts` using `this.server.tool(...)`. Use the Cloudflare Tools documentation for guidance.

How do I connect the server to a remote MCP client like Cloudflare AI Playground?

Go to https://playground.ai.cloudflare.com/, enter your deployed MCP server URL (e.g., `remote-mcp-server-authless.<your-account>.workers.dev/sse`), and the tools become available.

Can I use this server with Claude Desktop?

Yes, by using the `mcp-remote` proxy (package `mcp-remote`). Configure Claude Desktop’s MCP settings to run `npx mcp-remote <your-server-url>/sse`.
