Singapore Open Data MCP Server

An MCP (Model Context Protocol) server that gives AI agents access to Singapore's government open data from data.gov.sg. Query real-time information about weather, transport, property prices, air quality, and thousands of other datasets.

What can AI agents do with this?

• Check the weather - "What's the weather forecast for Tampines?"
• Find parking - "Are there available lots at Orchard carparks?"
• Track taxis - "How many taxis are available right now?"
• Check air quality - "What's the PSI reading in the East?"
• Research property - "Show me HDB resale prices in Bishan"
• Query any dataset - Access 1000+ government datasets
