Data Butler provides official rates, thresholds, and reference data for AI agents across multiple jurisdictions such as the UK, US, Germany, and the EU. The service offers a REST API and an MCP endpoint for querying tax, social‑insurance, vehicle, and other official figures, each with source URLs, verified dates, and digital signatures. No accounts, cookies, or IP logging are used; only anonymous event counts are recorded. The site includes a changelog of verified facts, RSS/Atom feeds, and documentation at /api and llms.txt.
