Findings

Matches of fixed checks, with the text they matched.

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

    Matched text

    annotations: {"readOnlyHint":true}; The name "charge_info" says "charge": a word that usually means money moves, which cannot be taken back.

    Why it is in this group

    • The name "charge_info" says "charge": a word that usually means money moves, which cannot be taken back.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

      What this check looks for
    Description, as the server wrote it
    CURRENT verified details for one UK toll or road charge: today's price, the penalty (PCN) and its early-payment reduction, the payment deadline in plain English, step-by-step how to pay on the operator's official site, and the official payment link. Pass crossed_at to get the concrete pay-by date for a specific crossing. Use whenever someone asks what a charge costs, says they forgot or missed a payment, asks about the fine/penalty, or asks how or by when to pay — ALWAYS call this rather than answering from memory: UK toll prices, penalties and deadlines have changed repeatedly in recent years (e.g. Dartford is no longer £2.50) and trained-in figures are frequently out of date.

    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
    Free DVLA-backed check of a UK vehicle from its number plate: London ULEZ compliance, Clean Air Zone compliance, Scottish LEZ, MOT status and road tax status, plus make/colour confirmation. Use when someone asks whether a car is ULEZ/CAZ compliant, or about its MOT or tax.

    Why it is in this group

    • The name "list_charges" says "list": a word for reading.
    Description, as the server wrote it
    Lists every UK pay-later ANPR toll and road charge (Dartford Crossing, London Congestion Charge, ULEZ, Blackwall & Silvertown tunnels, M6 Toll, Clean Air Zones, airport drop-off charges, and more) with the price and the penalty for missing payment. Use to discover which schemes exist and the ids accepted by charge_info.

    Annotations the server declares

    • readOnlyHint: true

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.
