VAT Validator MCP
AI-powered VAT fraud detection and live VAT number validation for AI agents.
Validates EU, UK, and AU VAT numbers against authoritative live sources and uses AI pattern analysis to detect invoice fraud before payment is authorised. Built for compliance agents, invoice processing workflows, and supplier onboarding pipelines.
What This Solves
VAT fraud costs EU businesses €50bn annually. The most common attack vectors — missing trader fraud, carousel fraud, deregistered entity re-use — share one common signal: a VAT number that looks valid but isn't registered to the entity on the invoice.
Claude and other LLMs cannot reliably check live VAT registration status from training data. This tool calls the authoritative sources directly:
- EU VIES — all 27 member states, real-time
- UK HMRC VAT API v2 — OAuth2, authoritative
- AU ABR — Australian Business Register
