FAQ from Building a Remote MCP Server on Cloudflare (Without Auth)

What does “Without Auth” mean?

The deployed MCP server does not enforce any authentication. Anyone with the SSE URL can access the tools.

How do I add custom tools?

Edit src/index.ts and define each tool inside the init() method using this.server.tool(...).

Can I connect from Claude Desktop?

Yes. Use the mcp-remote npm package as a proxy, then add the SSE URL to Claude Desktop’s MCP server configuration (Settings > Developer > Edit Config).

What transport does the server use?

The server communicates over SSE (Server‑Sent Events), as indicated by the /sse path in the deployment URL.
