Changes things 2Claude Code: ask
  • busiest_todayThe ten UK level crossings with the most predicted road-closed time today.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
    The ten UK level crossings with the most predicted road-closed time today. Takes no arguments. Each line gives the rank, crossing name, predicted minutes closed across the whole day, and a status URL ending .md. The ranking is computed from today's timetable once per day, shortly after UK midnight, and the build timestamp is included in the reply — it is a whole-day total, not a live reading, so use crossing_status for what a barrier is doing now. Briefly unavailable right after a restart while the first build runs.

    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Nearest listed level crossings to a point, closest first. Returns one line per crossing — distance in MILES, then name, type, region and a status URL ending .md. Distance is straight-line (great circle) between the point and the crossing, NOT distance by road or along the railway: it answers 'which crossings are near this place', not 'which will this train reach next'.

  • crossing_statusLive barrier status, the next-30-minute closure timeline and approaching trains for ONE crossing, as markdown.No findings

    Why it is in this group

    • The name "crossing_status" says "status": a word for reading.
    Description, as the server wrote it
    Live barrier status, the next-30-minute closure timeline and approaching trains for ONE crossing, as markdown. Forecasts are rebuilt per request from the live train feeds, so the answer changes minute to minute. Informational only — never a substitute for the signals and barriers at the crossing itself. An ambiguous name returns the candidate URL words to choose between; an unknown one asks you to call list_crossings first.

    Annotations the server declares

    • readOnlyHint: true
    • idempotentHint: true
    • openWorldHint: true
  • list_crossingsSearch UK level crossings by name, URL word or region name (substring, case-insensitive).No findings

    Why it is in this group

    • The name "list_crossings" says "list": a word for reading.
    Description, as the server wrote it
    Search UK level crossings by name, URL word or region name (substring, case-insensitive). Returns one line per match — name, crossing type, region, and a status URL ending .md that returns that crossing's live markdown status. Reports the total match count and returns the first `limit`; there is no pagination, so narrow the query to see different matches. Names starting with the query sort first.

    • readOnlyHint: true
    • idempotentHint: true
    • openWorldHint: 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.
