    Why it is in this group

    • The description's first verb is "fetch": a word for reading.
    Description, as the server wrote it
    Fetch a URL, expect an HTTP 402 response, and validate the JSON body against the x402 protocol shape (x402Version, accepts[] fields, resource/description). Free, no account. Returns a pass/fail report with concrete errors and warnings.

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.
