Introduction
GroundTruthData gives AI assistants cited, aggregated facts about South African places through the Model Context Protocol (MCP).
GroundTruthData is a remote MCP server. Once connected, your assistant can call a small set of bounded tools to answer questions about South African places (crime, rainfall, population and boundaries) and every number it gets back carries its source, licence, retrieval date and dataset version.
Quickstart

Each tool's inputs, caps, a cited example response and its errors.

How provenance is attached to every number.
What it is not
- Not a data download. Tools return aggregated answers with caps on rows and areas. No bulk exports.
- Not personal data. Sources are public statistics and boundaries; personal fields are dropped at extraction.
- Not advice. Answers are evidence for your own judgement, with the paper trail attached.
