MonstarX · Singapore MCP

Singapore's public data, ready for your AI.

Weather, buses, trains, carparks, HDB prices, the company registry, geocoding — Singapore's open data lives across a dozen government APIs, each with its own keys, formats and quirks. MonstarX unifies them into 35 tools any AI agent can call, through one endpoint, with no API keys. Stop writing integration glue. Start shipping Singapore-smart products.

02Connect your agent

MonstarX Singapore MCP is a remote HTTP server speaking the Model Context Protocol. Point any MCP-capable client at the endpoint — no auth handshake, it's stateless.

03Response format

Every call returns the payload twice — as a JSON string in content[0].text and as a parsed object in structuredContent (prefer this). Each payload wraps the data in a consistent provenance envelope so your agent always knows the source, agency and freshness.

__CB_ENV__

Field	Meaning
source	Upstream platform — data.gov.sg, LTA DataMall, OneMap.
agency	Originating government agency — NEA, LTA, HDB, ACRA, MOE, SLA.
api	The specific upstream API that was queried.
license	Data licence, when applicable (usually Singapore Open Data Licence).
retrieved_at	Server fetch time (UTC). Live timestamps inside `data` are usually SGT (+08:00).
data / results	The payload. List tools add context like `total`, `shown`, `found`.

04Errors

Errors come back as a normal result with isError: true and a message in content[0].text — not as a transport-level failure. Invalid or missing arguments return MCP error -32602. An empty data/results array is a valid "no matches", not an error.

__CB_ERR__

05All 35 tools

Every tool is prefixed sg_; required params are marked *. Hit Try in playground on any tool to load it above with a working example.
