常见问题

What prerequisites are needed?

You need a Cloudflare account and npm to run the `npm create cloudflare` command. No authentication is required for the MCP server itself.

How do I add my own tools?

Define each tool inside the `init()` method of `src/index.ts` using `this.server.tool(...)`. See Cloudflare’s tools documentation for details.

What is the deployed URL format?

The URL will be like `remote-mcp-server-authless.<your-account>.workers.dev/sse`.

How do I connect from Claude Desktop?

Use the `mcp-remote` npm package as a proxy. In Claude Desktop’s MCP configuration, set the command to `npx mcp-remote` with the server’s SSE URL as an argument.

Does this server support authentication?

No, this example explicitly deploys a remote MCP server without authentication.
