Malaysia Open Data MCP

MCP Endpoint: https://mcp.techmavie.digital/datagovmy/mcp

Analytics Dashboard: https://mcp.techmavie.digital/datagovmy/analytics/dashboard

MCP (Model Context Protocol) server for Malaysia's open data APIs, with tools for datasets, dashboards, DOSM, weather, floods, parquet files, and GTFS transit data.

This is not an official MCP server from the Government of Malaysia, Jabatan Digital Negara, or the Ministry of Digital.

Features

• Unified search across datasets and dashboards
• Live metadata fetching from data-gov-my/datagovmy-meta
• Pure JavaScript parquet parsing with raw, summary, and latest-period modes
• GTFS static and realtime transit tools
• Zero-credential geocoding for GTFS location search
• Built-in analytics endpoints and dashboard

Geocoding

GTFS location search now uses Nominatim (OpenStreetMap) only.

• No Google Maps, GrabMaps, or AWS credentials are required
• The hosted MCP URL works as-is with zero credentials
• Requests are throttled and cached to be friendlier to the public Nominatim service
• Self-hosted operators can optionally set NOMINATIM_CONTACT_EMAIL

Quick Start

Hosted server

Use the hosted endpoint directly:

https://mcp.techmavie.digital/datagovmy/mcp

Example MCP client config:

{
  "mcpServers": {
    "malaysia-opendata": {
      "transport": "streamable-http",
      "url": "https://mcp.techmavie.digital/datagovmy/mcp"
    }
  }
}

No API keys or geocoding credentials are needed.

Self-hosted

Detailed VPS instructions live in deploy/DEPLOYMENT.md.

npm run build
npm run start:http

Local Development

# Install dependencies
npm install

# Run the HTTP server in development mode
npm run dev:http

# Build and run the production server locally
npm run build
npm run start:http

# Verify the server
curl http://localhost:8080/health
curl -X POST http://localhost:8080/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Analytics

The hosted server exposes:

• /analytics for JSON stats
• /analytics/tools for tool usage stats
• /analytics/dashboard for the HTML dashboard

Configuration

Core environment variables

Variable	Default	Description
PORT	8080	HTTP server port
HOST	0.0.0.0	Bind address
API_BASE_URL	https://api.data.gov.my	Malaysia Open Data API base URL
CACHE_TTL	3600000	Metadata cache TTL in ms
AXIOS_TIMEOUT	30000	HTTP timeout in ms
GITHUB_FETCH_BATCH_SIZE	20	Concurrent GitHub metadata fetches
GH_PAT	empty	Optional GitHub token for higher GitHub API rate limits
ANALYTICS_RESET_KEY	empty	Secret key for analytics reset/import endpoints
ANALYTICS_DIR	/app/data	Analytics storage directory
FIREBASE_DATABASE_URL	empty	Firebase Realtime Database URL for analytics persistence
FIREBASE_CREDENTIALS_PATH	.credentials/firebase-service-account.json	Firebase service account path
NOMINATIM_CONTACT_EMAIL	empty	Optional contact email appended to Nominatim queries for self-hosted deployments

Example .env:

GH_PAT=your_github_pat_here
NOMINATIM_CONTACT_EMAIL=your-email@example.com
ANALYTICS_RESET_KEY=your_analytics_reset_key_here
ANALYTICS_DIR=/app/data
FIREBASE_DATABASE_URL=your_firebase_database_url_here
FIREBASE_CREDENTIALS_PATH=.credentials/firebase-service-account.json

Nominatim Notes

The server now depends on public Nominatim for GTFS location-name searches. The code includes:

• A custom User-Agent
• Optional email support via NOMINATIM_CONTACT_EMAIL
• Serialized requests with a 1 request/second floor
• Positive and negative result caching

If you expect sustained geocoding traffic, consider self-hosting a compatible geocoder or routing through your own approved service.
