OC Transpo MCP Server for Learning

A Model Context Protocol (MCP) server for OC Transpo Ottawa, providing real-time transit data to AI agents and developers.

Features

• get_vehicle_positions: Retrieves real-time latitude, longitude, and trip info for all active buses and trains.

• get_trip_updates: Fetches real-time arrival/departure delays and schedule updates.

• get_service_alerts: (Coming Soon) Standardized access to service disruptions (pending OC Transpo API activation).

• FastMCP Integration: Lightweight and easy to use with any MCP-compatible agent.

• GTFS-RT Support: Native protocol buffer parsing for live transit feeds.

Prerequisites

• Python 3.10+

• uv (recommended for dependency management)

• OC Transpo API Subscription Key (Get one at the OC Transpo Developer Portal)

Setup

1. Clone the repository:

   git clone <repository-url>

2. Configure environment variables: Create a .env file in the root directory:

   Ocp_Apim_Subscription_Key=your_key_here

3. Install dependencies:

   uv sync

Usage

Running the MCP Server

Start the server using uv:

uv run mcp-server.py

Testing with MCP Inspector

You can visually test the tools using the MCP Inspector:

npx -y @modelcontextprotocol/inspector uv run mcp-server.py

Scripting Example

You can use the helper script check_route.py to filter vehicles by route ID:

uv run check_route.py 62

Deployment

Google Cloud Run

You can deploy this server to Google Cloud Run to make it accessible over the internet via HTTPS.

1. Build and Deploy:

   gcloud run deploy octranspo-mcp \
     --source . \
     --region us-central1 \
     --allow-unauthenticated \
     --set-env-vars Ocp_Apim_Subscription_Key=YOUR_API_KEY

2. Access the Server: The server is probably live at: https://octranspo-mcp-PROJECT_ID.us-central1.run.app/mcp

Project Structure

• mcp-server.py: Main MCP server implementation.

• octranspo.py: API helper for GTFS-RT fetching and parsing.
