How to Use the WMATA MCP in Claude Code

Q: How do I get next train predictions at a specific station using WMATA and Claude Code?

Use getstationprediction. You pass in the required station code, and it returns predicted arrival times, line colors, and car counts. This is faster and more focused than system-wide checks.

Q: How do I list all WMATA bus routes in a script?

The simple call to getbusroutes returns every route ID, name, and description. You can then loop through these IDs for subsequent queries about service area coverage.

Q: Can Claude Code help with parking availability checks for WMATA?

Yes, running getparkinglots allows your script to check both system-wide or station-specific parking lot information. You get the count and general status of available spaces.

Run WMATA service checks in CI/CD pipelines using Claude Code's headless terminal execution.

Scripting Real-time Bus Tracking

A script needs to know where buses are. You call `get_bus_positions`, which returns vehicle IDs, lat/long coordinates, and deviation from schedule in seconds. This output is structured data perfect for processing in a CI/CD pipeline or writing into a database record.

Automating WMATA Station Connectivity Checks

For pre-deployment checks, run `get_elevator_incidents`. The tool returns affected station codes and outage descriptions, along with estimated repair times. This is essential for automated accessibility compliance reporting.

Systematic Rail Service Verification

You need to confirm system reliability? Run `get_rail_incidents`. It gives you detailed information on line impacts, incident types (like power problems or medical activity), and estimated resolution times. This makes it ideal for automated service status checks.
