Frequently asked questions

What does this server do that an alternative would not?

It provides a remote MCP server with zero authentication overhead, making it quick to deploy and test, whereas alternative servers often require API keys or user login.

What runtime or dependencies are required?

A Cloudflare Workers account and Node.js/npm to run the creation command. The deployed server runs entirely on Cloudflare's edge infrastructure.

Where does the server data live?

All MCP tool state and logic live in the Cloudflare Worker script; no external database or storage is configured by default.

What transport does it use?

It uses SSE (Server-Sent Events) over HTTP, accessible at a URL ending in `/sse`.

Does it support any authentication or authorization?

No — this template explicitly removes authentication, making it suitable only for development, testing, or public tool endpoints.
