UK Vet Medicines MCP

UK veterinary medicines data via the Model Context Protocol. Query VMD-authorised products, withdrawal periods, cascade prescribing rules, banned substances, and record-keeping requirements -- all from your AI assistant.

Part of Ansvar Open Agriculture.

Why This Exists

Farmers, vets, and farm assurance inspectors need quick access to withdrawal period data, cascade rules, and banned substance lists. This information is published by the Veterinary Medicines Directorate (VMD) but is spread across individual product SPCs, legislation, and guidance documents. This MCP server makes it all searchable in one place.

Food safety warning: Wrong withdrawal periods can lead to medicine residues entering the human food chain. This server is a reference tool -- always check the actual SPC for your specific product, dose, and route.
