- The name "find_transit" says "find": a word for reading.
- The description's first verb is "call": a word for a change.
- 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
Call with no arguments (or only `coverage`) to list the regions served and what each supports. Without a coverage, a name is searched in every region. If nothing matches, suggestions lists the closest names (not matches). Resolve a coverage, agency, route, station, stop, or a currently observed train number (where vehicle data exists); inspect an exact reference or nearby coordinates. Context ranks candidates without selecting identity. Candidates come best first (exact names and well-known place names such as SFO, then stations, then rail before bus), and each stop says what it is: stopType (station, platform or street stop), modes and the lines serving it, so you can pick the one the rider means. No general address geocoding. Use plan_trip for journeys.

plan_tripPlan an origin-to-destination journey.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
Plan an origin-to-destination journey. Returns up to three independently validated itineraries (the fastest, then other lines) and resolves named endpoints together; departure defaults to now. The search covers every line of the coverage, buses included. When no itinerary is possible (planning unavailable, a search too large, or nothing found) it returns routeHints: lines near each end and direct lines serving both. Call again with routes (the lines you would ride, from routeHints or your own knowledge) to plan along only those lines, which works wherever schedules exist. Present only returned itineraries as confirmed. The whole journey must finish within windowSeconds (default two hours): if none is found for a long trip, retry with a larger window. Each transit leg carries a tripInstanceRef; pass it to get_vehicle_status to see where that train is now. For a wheelchair user or anyone avoiding stairs, set accessibility: "step_free": journeys then board, alight and change only at platforms step-free from the street per the agency (partial stations by direction), avoiding stations cut off by a current elevator outage; in-station changes between such platforms are taken as step-free. It refuses with ACCESSIBILITY_UNAVAILABLE when no current elevator report exists and ENDPOINT_NOT_STEP_FREE when an endpoint has no step-free platform now (get_service_status lists the outages). Never present a journey pieced together from get_departures as confirmed; check it here with routes.

get_departuresFind what leaves a stop next, the first service or last service in a bounded window.No findings
Why it is in this group
- The name "get_departures" says "get": a word for reading.
Description, as the server wrote it
Find what leaves a stop next, the first service or last service in a bounded window. Pass a stopRef from find_transit, or a stop name with its coverage (one station complex resolves directly; different same-named stations return candidates). A station covers its whole complex, e.g. every line at Times Sq-42 St; a platform ref covers that platform. Pass toStop or toStopRef for the next trips from here that stop at a destination, each with its arrival time there. Returns dated trip references for get_vehicle_status. For a journey with a change use plan_trip (with routes where needed): departures alone cannot prove a connection.

Description, as the server wrote it
Check disruptions, delays, closures, elevator and escalator outages, or revalidate a chosen itinerary without replacing it.

Aggregate scopes include canonical service in the next 24 hours. equipment lists elevator/escalator outages: accessiblePath marks the step-free route, blocksStepFree marks stations step-free plan_trip avoids, and alternativeRoute is the agency's way around.

get_vehicle_statusWhere observed trains are right now.No findings
Why it is in this group
- The name "get_vehicle_status" says "get": a word for reading.
Description, as the server wrote it
Where observed trains are right now. Pass a route ref to list its trains, a dated trip ref (from get_departures or a plan_trip leg) to find that train, or a station (stopRef, or a name with coverage) to see trains stopped at or heading to it; a station covers its whole complex. Each train reports the stop it is at or heading to (stopStatus), the stop it last served, and its destination. Coordinates are the vehicle's own when the agency sends them (DC); otherwise a stopped train is placed at its station and a moving one has none. Never pass a bare train number: use find_transit.
