More Details Connect to Claude

Validating a European VAT number or a corporate Tax ID requires complex, country-specific mathematical algorithms. LLMs hallucinate these checks, which can lead to agents generating illegal invoices or fraudulent contracts. This MCP solves that entirely.

The Superpowers

  • Local Algorithmic Checking: Verifies the format and checksum of VAT numbers across all EU countries natively in V8.
  • B2B Billing Shield: Ensures that before your agent creates an invoice in Stripe or Xero, the tax ID is structurally valid.
