Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 28 October 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
