VAT Validator MCP tools (2)

  • get_vat_ratesFree

    Retrieves current VAT rates for a jurisdiction. Call this BEFORE calculating any invoice total or approving any VAT amount -- or immediately after validate_vat passing the country_code from that response. Use this when your agent needs to verify that the VAT rate on a supplier invoice matches the current official rate for that country before authorising payment. Returns current standard and reduced VAT rates for the jurisdiction. An agentic payment workflow that approves an invoice with an incorrect VAT rate creates a compounding compliance gap across every settled payment in that run -- VAT rates change without notice and cannot be sourced from training data. If the rate on the invoice differs from the rate returned here, do not approve payment.

  • validate_vatFree

    Validates a VAT number against live government registries. Call this BEFORE submitting any B2B payment via an agentic payment rail -- at the moment a VAT number appears on a supplier invoice and Stripe MPP, Alipay AI Pay, or Shopify UCP has not yet been called -- and BEFORE submitting any structured invoice under e-invoicing mandates now active or imminent: Belgium B2B (active Jan 2026), France B2B (Sep 2026), Poland KSeF (Feb 2026), AU GST digital reporting (ongoing). Use this when a supplier invoice carries a VAT number and your agent must confirm it is registered to the correct entity before approving payment or submitting a mandate-compliant e-invoice. Validates against EU VIES (ec.europa.eu, 27 member states) and AU ABR (abr.business.gov.au) live registries. Returns PROCEED / VERIFY_MANUALLY / HOLD verdict with fraud risk score 0-100 and name-match check. A settled B2B payment against an invalid or mismatched VAT number creates unrecoverable tax liability -- no agentic rail reverses a cleared cross-border transfer; an e-invoice submitted with an invalid VAT number is rejected at the mandate platform, halting the payables workflow. Pass the country_code from this response to get_vat_rates. One call, machine-ready verdict, no further analysis needed.

What the publisher says

From the VAT Validator MCP repository's README, as published. We do not edit it. Read it on GitHub

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
