Findings

Matches of fixed checks, with the text they matched.

1 warn
  • Warnestimate_charter

    The server marks "estimate_charter" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

    Matched text

    annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The input addresses people (input.to): what it sends cannot be taken back.

      What this check looks for
    Description, as the server wrote it
    An approximate charter cost for one aircraft at the hourly rate its owner published. Call it whenever the person you are helping asks what a trip would cost, with the departure and arrival airports: the beacon works out the legs and block hours from the owner's typical block speed, positioning included when the owner bills it. When the answer says the owner set no block speed, call again with block_hours, your own estimate for the routing. Answer with its sentence. Not a quote and not binding. Answers a reason instead of a figure when the owner has not published charter terms or a rate.

    Annotations the server declares

    • title: Approximate charter cost
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true
  • request_tripSends a charter trip request for one aircraft to the booking contact its owner named.No findings

    Why it is in this group

    • The name "request_trip" says "request": a word for a change.
    • The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
    • The input addresses people (input.to): what it sends cannot be taken back.
    Description, as the server wrote it
    Sends a charter trip request for one aircraft to the booking contact its owner named. Call it only after the person you are helping has asked to proceed, with their own name and email. Nothing is booked or held: the requester is emailed a link, the request is delivered only once they confirm it, and the booking contact then replies to them directly. If the owner set qualification questions, the first call answers needs_answers with the questions; ask the person each one and call again with their answers in the same order.

    Annotations the server declares

    • title: Request a charter trip
    • readOnlyHint: false
    • destructiveHint: false
    • openWorldHint: true
  • send_buyer_inquiryPasses a would-be buyer's message about acquiring one aircraft to the acquisition representative its owner named.No findings

    Why it is in this group

    • The name "send_buyer_inquiry" says "send": a word for sending, and what is sent cannot be taken back.
    Description, as the server wrote it
    Passes a would-be buyer's message about acquiring one aircraft to the acquisition representative its owner named. Call it only after the person you are helping has asked to contact the owner, with their own name, email and message. Nothing is offered or agreed: the buyer is emailed a link, the message is delivered only once they confirm it, and the representative then replies to them directly. If the owner set qualification questions, the first call answers needs_answers with the questions; ask the person each one and call again with their answers.

    • openWorldHint: true
Changes things 1Claude Code: ask
  • check_availabilityWhether one aircraft has anything scheduled on a date, or on each day of a span of up to 14 days, read from the live schedule its owner connected.No findings

    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.
    Description, as the server wrote it
    Whether one aircraft has anything scheduled on a date, or on each day of a span of up to 14 days, read from the live schedule its owner connected. Call it when the person you are helping asks whether the aircraft is available, with the departure date and, for a return trip, the return date, and answer with its sentence. Says free or taken per day and never what is scheduled. Not a hold and not a confirmation. Answers a reason instead when the owner does not publish availability.

    Annotations the server declares

    • title: Check availability
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true
Only reads 2Claude Code: allow
  • get_aircraftWhat public record says about one U.S.No findings

    Why it is in this group

    • The name "get_aircraft" says "get": a word for reading.
    Description, as the server wrote it
    What public record says about one U.S. registration mark, plus the facts its owner cleared for release. The same document as /{mark}/facts.json: status says what the registry answered (found, not_found, invalid or unavailable), public_record is the FAA registration and the datasets that reference it, and owner_approved is present only for an aircraft whose owner opened the machine-readable channel. Case and hyphens in the mark are ignored.

    Annotations the server declares

    • title: Aircraft record and owner-approved facts
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: true
  • search_aircraftThe aircraft whose owners chose to be listed on Owner Connect, filtered by minimum passenger seats, base airport, aircraft type, charter signal or sales signal.No findings

    Why it is in this group

    • The name "search_aircraft" says "search": a word for reading.
    Description, as the server wrote it
    The aircraft whose owners chose to be listed on Owner Connect, filtered by minimum passenger seats, base airport, aircraft type, charter signal or sales signal. Every filter is applied to the facts the owner cleared for release, so an aircraft whose owner did not publish its seat count never matches a seats filter. Returns each aircraft's owner_approved block; call get_aircraft for the public record.

    Annotations the server declares

    • title: Listed aircraft by seats, base, type or signal
    • readOnlyHint: true
    • destructiveHint: false
    • idempotentHint: true
    • openWorldHint: false

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.
