VAT Validator MCP

Connects Claude and other AI agents to live VAT registries in the EU (VIES), UK (HMRC VAT API v2), and Australia (ABR) for real-time validation before invoice approval or supplier onboarding. Exposes six tools including validate_vat, validate_uk_vat, and analyse_vat_risk for fraud detection targeting missing trader and carousel schemes. The compare_invoice_details tool cross-checks VAT numbers against invoice entities to catch deregistered fraud. Available over SSE with a 50-call free tier, then pay-per-query or prepaid bundles. Designed for compliance agents and accounts payable workflows where outdated VAT data from training sets won't cut it.
