mbta_departures
Pack: mbta · Endpoint: https://gateway.pipeworx.io/mbta/mcp
Real-time MBTA train arrival and departure predictions at a Boston station — answers “when is the next train Boston”, next Red Line subway at South Station, Green Line trolley, commuter rail departures, Silver Line and bus arrivals. Accepts a station name (“South Station”, “Harvard”) or a place id (“place-sstat”). Falls back to the published schedule when live predictions are empty (common for commuter rail off-peak). Example: mbta_departures({ stop: “South Station”, route: “Red” })
