FAQ

Frequently asked questions

What is GroundTruthData?

A paid MCP (Model Context Protocol) server. Connect it to Claude, ChatGPT or any MCP client and your assistant can answer questions about South African places with aggregated, cited facts on crime, rainfall, population, boundaries and mapped facilities.

Where do the numbers come from?

Public sources: SAPS crime statistics and police precinct boundaries, Municipal Demarcation Board 2026 boundaries, CHIRPS rainfall, WorldPop population and OpenStreetMap facility counts. Every number in an answer carries its source, licence, retrieval date and dataset version. See the coverage page for the full list.

Can I download the raw datasets?

No. We sell answers, not data. Tools return bounded, aggregated results with attribution, never bulk exports of source rows. That keeps us within the source licences and keeps answers honest.

How do I connect it?

Add https://mcp-staging-1eb0.up.railway.app/mcp as a custom connector in Claude or ChatGPT and sign in, or use an API key from your dashboard with Claude Code or any MCP client. The quickstart walks through each one in a few minutes.

What happens when I reach my limit?

Calls are refused until the daily or monthly window resets. There are no overage charges and no surprise bills. We email you at 80% and 100% of your monthly limit, and you can upgrade at any time.

Do you store personal information?

Not in the data. We drop personal fields at extraction. For your account we keep only what sign-in needs (email, name, avatar) and usage counts per tool call. Your prompts and conversations stay with your AI assistant; we see only the tool calls it makes.

Are answers at ward level exact?

Answers come at each source's native geography by default. When we convert between geographies (for example, police precincts to wards) the answer is labelled as an estimate.

Who runs it?

BI Branch (Pty) Ltd, a South African company. Billed monthly by BI Branch (Pty) Ltd through Paystack. Prices in ZAR. BI Branch (Pty) Ltd is not registered for VAT, so no VAT is added.
