# 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](/docs/quickstart): Connect Claude, ChatGPT or Cursor in a few minutes.
  - [Authentication](/docs/authentication): OAuth sign-in for connectors, API keys for agents and scripts.
  - [Tools](/docs/tools): Each tool's inputs, caps, a cited example response and its errors.
  - [For agents](/docs/agents): Markdown twins of every page, llms.txt and llms-full.txt.
  - [Citations](/docs/citations): 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.
