MCP tool

descriptions.py

Versioned descriptions (`v1` baseline, `v1b` ablation, `v2` optimized, or a JSON file)

The descriptions.py tool is provided by GitHub (read-only). Install that server in your AI client and the assistant can call it directly.

Servers exposing descriptions.py

Tool lists are read from the live servers (or, for packaged servers, from their documentation) each morning, so this reflects what they exposed at the last refresh. Search all tools.
