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.

Related MCP server: transport-gzm

Prerequisites

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.

  • check_route.py: CLI tool for filtering live data.

  • test_api.py: Connectivity and data parsing verification script.
