• 01

  Do I need to pay for CTA API keys?

  No, both the CTA Train Tracker and Bus Tracker API keys are available for free through the CTA Developer Portal.

• 02

  Which AI clients can I use with this MCP?

  You can use this MCP with any compatible client, including Claude, Cursor, and Windsurf.

• 03

  Can I track both buses and trains?

  Yes, the MCP provides capabilities for real-time bus tracking, bus stop predictions, L train positions, and L train arrival times.

• 04

  How accurate are the arrival predictions?

  Predictions are based on real-time vehicle tracking and current schedule adherence provided by the CTA.

• 05

  Can I see if there are delays on specific lines?

  Yes, you can use the route status capability to check if lines are running on time, experiencing severe delays, or have suspended service.

• 06

  Can my AI check when the next L train is arriving at my station?

  Yes! Use the get_train_arrivals capability with the station mapId (a 5-digit parent station ID, e.g., 40360 for Clark/Lake, 40900 for Jackson). Your AI will return all upcoming trains with destination names, line colors (Red, Blue, Brown, Green, Orange, Purple, Pink, Yellow), predicted arrival times in minutes, operating status (on-time, delayed, approaching, boarding, departing), and whether the train is scheduled or real-time tracked. If you do not know the mapId, it can be found in the CTA GTFS static data feed.

• 07

  How do I check when the next CTA bus is arriving at a specific stop?

  First use get_bus_stops with a route ID to find the stop ID (stpid) for your location. Then use get_bus_predictions with that stop ID to get real-time estimated arrival times, route information, destination descriptions, and vehicle IDs. For route-filtered predictions, you can also pass the route ID to narrow results to a specific bus line. Stop IDs are numeric identifiers assigned by CTA to each physical bus stop across Chicago.

• 08

  Are there any service disruptions affecting the Red Line or my bus route right now?

  Use get_service_alerts to check all active service disruptions across the CTA system. This returns alerts with affected routes and stations, disruption descriptions, severity levels, cause types (maintenance, incident, weather, special events, construction), and detour information. You can also use get_route_status for a quick system-wide health check showing which L lines and bus routes are running on-time, delayed, or have planned work. Always check this before planning any CTA journey.
