Can't be undone 1Claude Code: ask
  • convert_unitsConvert a number from one unit to another and return the exact factor, whether the factor is exact by definition, and the URL of the page that explains it.No findings

    Why it is in this group

    • The name "convert_units" says "convert": a word for a change.
    • The input addresses people (input.to): what it sends cannot be taken back.
    Description, as the server wrote it
    Convert a number from one unit to another and return the exact factor, whether the factor is exact by definition, and the URL of the page that explains it. Supports linear units (length, mass, volume, energy, …) and temperature. Currency is deliberately not supported.

  • list_categoriesLists every category with its type (linear, temperature, …), base unit and unit keys.No findings

    • The name "list_categories" says "list": a word for reading.
    Description, as the server wrote it
    Lists every category with its type (linear, temperature, …), base unit and unit keys. Use this to find valid `from`/`to` keys before calling convert_units.
  • list_conversionsLists the 213 hand-written conversion pages, optionally limited to one category.No findings

    Why it is in this group

    • The name "list_conversions" says "list": a word for reading.
    Description, as the server wrote it
    Lists the 213 hand-written conversion pages, optionally limited to one category. Each entry carries the canonical URL, which is the page to cite.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
