`list_tools`

15 servers reported a tool by this name when we called them. Names are chosen by whoever wrote the server, so two tools sharing a name do not have to do the same thing. We record what was reported, not what it does.

15 of these answered an MCP handshake on the day we checked. That is not a promise the tool works, only that the server was running and told us the tool existed.
