    Why it is in this group

    • The name "airport_status" says "status": a word for reading.
    • The input takes a statement or command to run (input.code), which can change anything it can reach.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    Description, as the server wrote it
    Current FAA status for one US airport: normal, advisory or disrupted, max severity (0-5) and each active event (ground stop, ground delay program with average/max delay, arrival/departure delays, closure). Price: $0.002 USDC per call via x402 (Base); the first 5 calls per day per client are free.

    Annotations the server declares

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

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.
