A tool below is one the server NAMES. Nobody has called it. That is the same two tier honesty rule the rest of the directory runs on: a named tool is research, and BENCH-TESTED stays the only claim that anybody ran anything.
This list came from a repo the vendor does not own. Those are that author's tools for the vendor's API, not the vendor's own published surface, and the two must not be read as the same thing.
