# 🚂 Caltrain MCP Server (Because You Love Waiting for Trains)

[![CI & Semantic release](https://github.com/davidyen1124/caltrain-mcp/actions/workflows/ci.yml/badge.svg?branch=main)](https://github.com/davidyen1124/caltrain-mcp/actions/workflows/ci.yml)

A Model Context Protocol (MCP) server that promises to tell you _exactly_ when the next Caltrain will arrive... and then be 10 minutes late anyway. Uses real GTFS data, so at least the disappointment is official!

## Features (Or: "Why We Built This Thing")

- 🚆 **"Real-time" train schedules** - Get the next departures between any two stations (actual arrival times may vary by +/- infinity)
- 📍 **Station lookup** - Because apparently 31 stations is too many to memorize 🤷‍♀️
- 🕐 **Time-specific queries** - Plan your commute with surgical precision, then watch it all fall apart
- ✨ **Smart search** - Type 'sf' instead of the full name because we're all lazy here
- 📊 **GTFS-based** - We use the same data Caltrain does, so when things go wrong, we can blame them together

## Setup (The Fun Part 🙄)

1. **Install dependencies** (aka "More stuff to break"):

   ```bash
   # Install uv if you haven't already (because pip is apparently too mainstream now)
   curl -LsSf https://astral.sh/uv/install.sh | sh

   # Install dependencies using uv (fingers crossed it actually works)
   uv sync
   ```

2. **Get that sweet, sweet GTFS data**:
   The server expects Caltrain GTFS data in the `src/caltrain_mcp/data/caltrain-ca-us/` directory. Because apparently we can't just ask the trains nicely where they are.

   ```bash
   uv run python scripts/fetch_gtfs.py
   ```

   This magical script downloads files that contain:

   - `stops.txt` - All the places trains pretend to stop
   - `trips.txt` - Theoretical journeys through space and time
   - `stop_times.txt` - When trains are _supp…
