Quickstart
Connect GroundTruthData to Claude, ChatGPT, Cursor or any MCP client.
The MCP endpoint is:
https://mcp.groundtruthdata.co.za/mcpYou need an account and an active plan. Create an account, choose a plan, then pick your client.
Connector (OAuth) sign-in is coming at launch; until then, use an API key (see the Claude Code and Other MCP clients tabs).
Open Settings → Connectors and choose Add custom connector.
Name it GroundTruthData and paste the endpoint URL above. Leave the OAuth fields empty: Claude
discovers our authorization server automatically.
Click Connect. You are sent to groundtruthdata.co.za to sign in and approve access.
In a new chat, enable the connector from the tools menu and ask, for example: “Compare residential burglary in Stellenbosch and Drakenstein over the last three financial years, with sources.”
Check it works
Ask your assistant to call describe_catalog (free, it does not count against your plan). It
lists the metrics, geographies and per-call limits. Then see the Tool reference.
Keep keys secret
API keys are shown once. Store them in your secrets manager or environment, never in a repository. Revoke a key from the dashboard the moment you suspect it leaked.
