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

Yes! Use the `get_subway_feed` tool with the appropriate feed ID for your line. Feed IDs are grouped: "1" covers lines 1,2,3,4,5,6,S; "2" covers A,C,E; "3" covers B,D,F,M; "4" is G; "5" is J,Z; "6" covers N,Q,R,W; "7" is L; "11" is Staten Island Railway. This returns real-time GTFS-RT data with train positions, trip updates, scheduled vs. real-time arrivals, and delay information. For station-level predictions, combine with `get_stations` to find your station code first.

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

First use `get_bus_stops` with a route ID to find the stop ID (MonitoringRef) for your location. Then use `get_bus_predictions` with that stop ID to get real-time estimated arrival times, route information, destinations, and delay indicators. For more targeted predictions, use `get_bus_estimated_arrival` which allows filtering by both stop ID and route ID. Stop IDs are numeric identifiers assigned by MTA to each physical bus stop across NYC.

MTA MCP Tools for Google ADK (12)

These 12 tools become available when you connect MTA to Google ADK via MCP:

get_bus_estimated_arrival

Returns predicted arrival times, route information, destinations, wait times, and delay indicators for each expected bus. Supports both multi-route stop queries and single-route filtered queries. Essential for targeted arrival predictions, route-specific wait time estimation, and passenger trip timing. AI agents should reference this when users ask "when is the next M15 at this stop", "show arrival estimates for route B46 at stop 12345", or need route-filtered arrival data at a specific bus stop. Get estimated arrival times for buses at a stop, optionally filtered by route

get_bus_predictions

MTA + Google ADK FAQ

Common questions about integrating MTA MCP Server with Google ADK.

How does Google ADK connect to MCP servers?

Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.

Can ADK agents use multiple MCP servers?

Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.

Which Gemini models work best with MCP tools?

Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
