VAT Validator MCP

Call this BEFORE your agent approves any supplier invoice, onboards a new EU/UK/AU vendor, or processes any cross-border payment. Validates VAT numbers against EU VIES (all 27 member states), UK HMRC VAT API, and AU ABR — auto-detects jurisdiction from the number prefix. Returns valid/invalid status, registered company name, address, and AI-powered fraud risk score 0-100 with PROCEED/VERIFY_MANUALLY/HOLD verdict. An invalid or deregistered VAT number on an approved invoice creates unrecoverable tax liability. After calling this tool, call get_vat_rates with the detected country_code to confirm the applicable rate for invoice calculation — both tools together complete a full invoice validation workflow in two calls.

Call this AFTER validate_vat to confirm the current VAT rate applicable to the validated supplier's jurisdiction, or call standalone before your agent calculates invoice totals, applies tax rates, or generates VAT-inclusive pricing. Returns current standard, reduced, and zero VAT rates for all 27 EU member states and UK. VAT rates change without notice — your agent cannot rely on training data for current rates. Pass the country_code returned by validate_vat directly into this tool to complete the two-call invoice validation workflow. Returns machine-readable JSON — no parsing needed. Omit country_code to get all countries.
