Malaysia Open Data MCP

MCP (Model Context Protocol) server for Malaysia's Open Data APIs, providing easy access to government datasets and collections.

Do note that this is NOT an official MCP server by the Government of Malaysia or anyone from Malaysia's Open Data/Jabatan Digital Negara/Ministry of Digital team.

Architecture

This MCP server implements a hybrid approach for efficient data access:

• Pre-generated Static Indexes for listing and searching datasets and dashboards
• Dynamic API Calls only when specific dataset or dashboard details are requested

This approach provides several benefits:

• Faster search and listing operations
• Reduced API calls to external services
• Consistent data access patterns
• Up-to-date detailed information when needed

Documentation

• TOOLS.md - Detailed information about available tools and best practices
• PROMPT.md - AI integration guidelines and usage patterns

AI Integration

When integrating this MCP server with AI models:

1. Use the unified search tool first - Always start with search_all for any data queries
2. Follow the correct URL patterns - Use https://data.gov.my/... and https://open.dosm.gov.my/...
3. Leverage Parquet file tools - Use parse_parquet_file to access data directly or get_parquet_info for metadata
4. Use the hybrid approach - Static indexes for listing/searching, API calls for details
5. Consider dashboard visualization - For complex data, use the dashboard links provided by find_dashboard_for_parquet
6. Leverage the multi-provider Malaysian geocoding - For Malaysian location queries, the system automatically selects the best provider (GrabMaps, Google Maps, or Nominatim) with fallback to Nominatim when no API keys are configured

Refer to PROMPT.md for comprehensive AI integration guidelines.

Configuration

Environment Variables

This project supports the following configuration options:

Geocoding Credentials (Optional. Only for GTFS Transit Features Usage):

The following credentials are only needed if you plan to use the GTFS transit tools that require geocoding services. Other features like data catalogue access, weather forecasts, and DOSM data do not require these credentials.

• googleMapsApiKey: Optional. If provided, the system will use Google Maps API for geocoding location names to coordinates.
• grabMapsApiKey: Optional. Required for GrabMaps geocoding, which is optimized for locations in Malaysia.
• awsAccessKeyId: Required for GrabMaps integration. AWS access key for GrabMaps API authentication.
• awsSecretAccessKey: Required for GrabMaps integration. AWS secret key for GrabMaps API authentication.
• awsRegion: Required for GrabMaps integration. AWS region for GrabMaps API (e.g. 'ap-southeast-5' for Malaysia region or ap-southeast-1 for Singapore region).

If neither Google Maps nor GrabMaps API keys are provided, the GTFS transit tools will automatically fall back to using Nominatim (OpenStreetMap) API for geocoding, which is free and doesn't require credentials.

You can set these configuration options in two ways:

1. Through Smithery's configuration interface when connecting to the MCP server
2. As environment variables (GOOGLE_MAPS_API_KEY, GRAB_MAPS_API_KEY) for local development

Setting up environment variables

For local development:

The project uses dotenv to load environment variables from a .env file during development.

1. Create a .env file in the root directory with the following content:

GOOGLE_MAPS_API_KEY=your_google_api_key_here
GRAB_MAPS_API_KEY=your_grab_api_key_here
AWS_ACCESS_KEY_ID=your_aws_access_key_for_grabmaps
AWS_SECRET_ACCESS_KEY=your_aws_secret_key_for_grabmaps
AWS_REGION=ap-southeast-5 # Malaysia region or ap-southeast-1 # Singapore region

2. The variables will be automatically loaded when you run the server locally using npm run dev

For Smithery deployment:

When connecting to your MCP server through Smithery:

1. Click on "Connect Malaysia Open Data MCP Server"
2. You'll see configuration options for:
   • googleMapsApiKey - Google Maps API key
   • grabMapsApiKey - GrabMaps API key
   • awsAccessKeyId - AWS access key for GrabMaps
   • awsSecretAccessKey - AWS secret key for GrabMaps
   • awsRegion - AWS region for GrabMaps (e.g. ap-southeast-5 for Malaysia region or ap-southeast-1 for Singapore region)
3. Enter your API keys and AWS credentials in these fields
4. Click "Get Link" to generate your connection URL

The API keys will be securely passed to the server during connection.

Note: For Malaysian locations, GrabMaps provides the most accurate geocoding results, followed by Google Maps, with both requiring API keys. If you don't provide either API key, the system will automatically use Nominatim API instead, which is free but may have less accurate results for some locations in Malaysia.

Important: These geocoding credentials are only required for the following GTFS transit tools:

• get_transit_routes - When converting location names to coordinates
• get_transit_stops - When converting location names to coordinates
• parse_gtfs_static - When geocoding is needed for stop locations

Note about GTFS Realtime Tools: The parse_gtfs_realtime tool is currently in development and has limited availability. Real-time data access through this MCP is experimental and may not be available for all providers or routes. For up-to-date train and bus schedules, bus locations, and arrivals in real-time, please use official transit apps like Google Maps, MyRapid PULSE, Moovit, or Lugo.

All other tools like data catalogue access, dashboard search, weather forecasts, and DOSM data do not require any geocoding credentials.
