Yes. No account, no key and no rate card. It is read-only.

What data does it return?

The same catalog as db.fyi: published tools and MCP servers only. Every fact says how we know it (checked by an editor, confirmed by the vendor, or read from the source page), with the source URL and the date we checked.

Does it log what I ask?

We count how often each tool is looked up, so we can see which tools people need. We do not store your questions or anything that identifies you.

Are results ranked by who pays?

No. Tools reviewed by an editor come first, then live tools, then by quality. Paid plans never change the order.

Which protocol does it use?

MCP Streamable HTTP with JSON responses, protocol versions 2025-06-18, 2025-03-26 and 2024-11-05. A GET on the endpoint returns a short description.
