Transport NSW API Client (MCP Implementation)

A Claude MCP for interacting with the Transport NSW API using direct HTTP requests.

About

This project implements a Model Context Protocol (MCP) service for Transport NSW’s API.

Setup

1. Clone this repository
2. Install dependencies using uv (fast Python package manager):

   uv venv
   uv sync
   

3. Create a .env file with your API key:

   OPEN_TRANSPORT_API_KEY=your_api_key_here
   

4. (Optional) Run the MCP Inspector:

   uv run mcp dev api.py
   

   And visit the server at http://localhost:5173 (port might be different).

Features

• Stop Finder API: Find transport stops by name or coordinates
• Alerts API: Get information about transport alerts and disruptions
• Departure Monitor API: Get real-time departure information for transport stops
• MCP Implementation: Structured as a Model Context Protocol service

Usage Examples

MCP Examples coming soon. Standard Python examples below:

Find Transport Stops

from api import find_transport_stops

# Search by name
stops = find_transport_stops(stop_name="Central Station")

# Search by coordinates (Central Station area)
central_station = '151.206290:-33.884080:EPSG:4326'
stops = find_transport_stops(coord=central_station, radius=500)

Get Transport Alerts

from api import get_transport_alerts

# Get all current alerts
alerts = get_transport_alerts()

# Get alerts for a specific date
date_alerts = get_transport_alerts(date='22-03-2025')

# Get train alerts only (mot_type=1)
train_alerts = get_transport_alerts(mot_type=1)

Monitor Real-time Departures

from api import get_departure_monitor

# Get departures from Central Station
departures = get_departure_monitor("200060")  # Central Station ID

# Get departures for a specific time
from datetime import datetime
time_departures = get_departure_monitor("200060", time="15:30")

# Get only train departures
train_departures = get_departure_monitor("200060", mot_type=1)  # 1 = Train

Demo Script

The project includes a comprehensive demo script that showcases all API functionality:

# Run the full demo
python demo.py

# Run specific sections
python demo.py --stops       # Stop finder demo
python demo.py --alerts      # Transport alerts demo
python demo.py --departures  # Departure monitoring demo

Testing

Local Testing

Run the complete test suite with pytest:

uv run pytest

Run with coverage reporting:

uv run pytest --cov=api

Continuous Integration

Tests automatically run on GitHub Actions for every push and pull request to the main branch. The workflow:

1. Sets up Python 3.10
2. Installs uv and project dependencies
3. Runs tests with coverage reporting

To use this feature:

1. Add your OPEN_TRANSPORT_API_KEY as a GitHub repository secret
2. Push your code to GitHub

MCP Integration

This project follows the Model Context Protocol specification, allowing AI models to access Transport NSW data through a standardized interface.

Package Management

This project uses uv, a modern Python package manager written in Rust. Dependencies are managed through:

• pyproject.toml: Defines project dependencies
• uv.lock: Locks dependency versions for reproducible environments
