Bengaluru BMTC MCP Server

An implementation of a Mall Connector Program (MCP) server for Bangalore Metropolitan Transport Corporation (BMTC) bus services.

Architecture

The BMTC MCP server follows a modular, layered architecture that separates concerns and promotes maintainability. The system is designed to handle real-time transit data from Bangalore Metropolitan Transport Corporation buses and provide it through a standardized API.

Core Components

  1. API Layer: RESTful endpoints for authentication, routes, stops, bus locations, and ETA information
  2. Service Layer: Business logic, data transformation, and ETA calculations
  3. Data Access Layer: MongoDB integration via Mongoose ODM
  4. Caching Layer: Redis-based caching for improved performance
  5. External Integration Layer: BMTC API integration

Read the full architecture documentation

Features

  • Real-time bus location tracking
  • Route information and scheduling
  • Stop details and ETA (Estimated Time of Arrival)
  • Support for over 2,200 bus routes and 8,400+ bus stops in Bengaluru
  • Authentication and authorization
  • Data caching and optimization
  • GeoSpatial queries for nearby stops and buses

Prerequisites

  • Node.js (v14 or later)
  • npm or yarn
  • MongoDB
  • Redis (optional, for caching)
  • Git

Installation and Setup

Method 1: Standard Installation

  1. Clone the repository
git clone https://github.com/ajeetraina/bengaluru-bmtc-mcp.git cd bengaluru-bmtc-mcp
  1. Install dependencies
npm install
  1. Configure environment variables
cp .env.example .env

Edit the .env file with your configuration:

PORT=3000 NODE_ENV=development MONGO_URI=mongodb://localhost:27017/bmtc-mcp REDIS_URI=redis://localhost:6379 API_KEY=your_api_key_here JWT_SECRET=your_jwt_secret_here JWT_EXPIRES_IN=86400 BMTC_API_ENDPOINT=https://bmtc-api-endpoint.example BMTC_API_KEY=your_bmtc_api_key_here CACHE_DURATION=300 LOG_LEVEL=info
  1. Seed the database with mock data (optional)
node src/scripts/seed.js
  1. Start the server
npm start

For development with auto-restart:

npm run dev

Method 2: Using Docker Compose

  1. Clone the repository
git clone https://github.com/ajeetraina/bengaluru-bmtc-mcp.git cd bengaluru-bmtc-mcp
  1. Configure environment variables (optional)

You can modify the environment variables directly in the docker-compose.yml file or create a .env file:

cp .env.example .env
  1. Build and start the containers
docker-compose up -d

This will start three containers:

  • bmtc-mcp-api: The Node.js API server
  • bmtc-mcp-mongo: MongoDB database
  • bmtc-mcp-redis: Redis cache server
  1. Seed the database with mock data (optional)
docker-compose exec api node src/scripts/seed.js
  1. View logs
docker-compose logs -f api
  1. Stop the containers
docker-compose down

To remove volumes as well:

docker-compose down -v

Using the API

Once the server is running, you can access the API at:

http://localhost:3000/api/v1

For API documentation, visit:

http://localhost:3000/api-docs

Example API Endpoints

# Authentication POST /api/v1/auth/login GET /api/v1/auth/me # Routes GET /api/v1/routes GET /api/v1/routes/:routeId GET /api/v1/routes/search?source=Kempegowda&destination=Electronic # Stops GET /api/v1/stops GET /api/v1/stops/:stopId GET /api/v1/stops/near?lat=12.9767&lng=77.5713&radius=500 GET /api/v1/stops/search?query=Lalbagh # Bus Locations GET /api/v1/bus-locations GET /api/v1/bus-locations/:busId GET /api/v1/bus-locations/near?lat=12.9767&lng=77.5713&radius=1000 # ETA GET /api/v1/eta/:stopId GET /api/v1/eta/:stopId/:routeId

API Keys

JWT Secret

The JWT secret is used for signing authentication tokens. Generate a secure random string:

node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"

Add this to your .env file:

JWT_SECRET=your_generated_secret_here

BMTC API Key

For development, you can use mock data without an actual BMTC API key:

BMTC_API_ENDPOINT=https://bmtc-api-endpoint.example BMTC_API_KEY=your_bmtc_api_key_here

For production, you would need to contact BMTC directly to request official API access.

Development

Testing

Run the tests:

npm test

Run tests with coverage:

npm run test:coverage

Linting

Check code style:

npm run lint

Fix code style issues:

npm run lint:fix

remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

Provides real-time access to Bangalore's public transportation information including bus tracking, schedules, routes, and service updates to improve passenger experience.
