🇸🇬 Singapore MCP

Open-source Model Context Protocol servers for Singapore public data and services.

Built and maintained in Singapore by Olano.

This is an independent community project. It is not affiliated with, endorsed by, or an official product of the Singapore Government or any government agency.

Packages

All packages support local stdio and Streamable HTTP transports.

Related MCP server: Gahmen MCP Server

Quick start

Run the full Singapore suite over stdio:

npx @olano/mcp-singapore

Or run a focused server:

npx @olano/mcp-onemap
npx @olano/mcp-weather

Run the aggregate server over Streamable HTTP:

npx @olano/mcp-singapore --transport http --host 127.0.0.1 --port 3000

The MCP endpoint is http://127.0.0.1:3000/mcp. The default bind address is localhost. Put authentication and TLS in front of any internet-facing deployment.

Client configuration

Add the aggregate server to a client that accepts the common mcpServers JSON format:

{
  "mcpServers": {
    "singapore": {
      "command": "npx",
      "args": ["-y", "@olano/mcp-singapore"],
      "env": {
        "DATA_GOV_SG_API_KEY": "optional-data-gov-key",
        "ONEMAP_TOKEN": "your-onemap-token",
        "LTA_DATAMALL_API_KEY": "optional-lta-account-key"
      }
    }
  }
}

Remove unused environment variables. Never commit real credentials.

Tools

Tool names are namespaced and stable:

• datagov_list_datasets, datagov_get_dataset_metadata, datagov_list_dataset_rows

• datagov_get_realtime

• onemap_search, onemap_reverse_geocode, onemap_route

• lta_bus_arrivals, lta_list_bus_stops, lta_traffic_incidents

• lta_traffic_images, lta_carpark_availability, lta_taxi_availability

• weather_two_hour_forecast, weather_twenty_four_hour_forecast

• weather_four_day_outlook, weather_temperature, weather_rainfall, weather_air_quality

• singapore_location_brief

The servers are read-only. Inputs are validated with Zod, upstream origins and API paths are fixed in code, requests have timeouts and response-size limits, transient requests are retried, and GET responses are cached briefly. Upstream calls are start-rate-limited per provider client to avoid bursts against public services.

Credentials

LTA dynamic APIs require registration. OneMap APIs require a OneMap account and token. Public data.gov.sg real-time endpoints can be tested without a key, but production users should obtain one.

Data sources and attribution

• data.gov.sg API guide

• OneMap API documentation

• LTA DataMall

• Meteorological Service Singapore

• Singapore Open Data Licence

API availability, data accuracy, rate limits, and upstream terms are controlled by their respective providers. Applications using returned data must comply with the relevant source terms and attribution requirements.

Development

npm install
npm run format:check
npm run lint
npm test
npm run build

Use the official MCP Inspector for interactive testing:

npx @modelcontextprotocol/inspector node packages/singapore/dist/cli.js

See Architecture, Contributing, and Security.

Roadmap

• Focused HDB and URA packages over documented public datasets

• ACRA public company-data discovery, subject to dataset terms and practical pagination

• More cross-agency neighbourhood, mobility, and business-location tools

• Hosted authenticated endpoints and MCP Registry publication

• SingStat interoperability rather than duplicating Singapore Department of Statistics' official MCP
