MCP tools

The server provides the following tools:

1. getCurrentTimetable : Retrieves current timetable data for a station

   • Parameter: evaNo - EVA number of the station (e.g. 8000105 for Frankfurt Hbf)

2. getRecentChanges : Retrieves recent changes for a station

   • Parameter: evaNo - EVA number of the station (e.g. 8000105 for Frankfurt Hbf)

3. getPlannedTimetable : Retrieves planned timetable data for a station

   • Parameter:

     • evaNo - EVA number of the station (e.g. 8000105 for Frankfurt Hbf)

     • date - Date in YYMMDD format (e.g. 230401 for 01.04.2023)

     • hour - hour in HH format (e.g. 14 for 2 p.m.)

4. findStations : Searches for stations using a search pattern

   • Parameter: pattern - search pattern (e.g. "Frankfurt" or "BLS")

MCP resources

The server provides the following resources:

1. Current timetable data : db-api:timetable/current/{evaNo}

2. Current timetable changes : db-api:timetable/changes/{evaNo}

3. Planned timetable data : db-api:timetable/planned/{evaNo}/{date}/{hour}

4. Station search : db-api:station/{pattern}

Development

Project structure

NPM scripts

• npm run build : Compiles the TypeScript code

• npm start : Starts the server

• npm run dev : Starts the server in development mode with automatic reloading

• npm test : Runs tests

Extensibility

Potential extensions

1. Data processing and enrichment

   • Semantic timetable data processing: XML to structured JSON with semantic enrichment

   • Historical data analysis for delays and disruptions

   • Integration of multimodal transport connections

2. Advanced MCP tools

   • Route planning between stations

   • AI-based delay and capacity forecasts

   • Travel disruption analysis

   • Accessibility check for stations and connections
