Returns current VAT rates for all EU member states (plus XI for Northern Ireland). Use when the user asks for an overview, a comparison across countries, or "all EU VAT rates". For a single country prefer get_country_vat_rates. Data is sourced from the EU Commission TEDB and updated daily. Free, no API key required.

Returns the standard, reduced, super-reduced and parking VAT rates for a single European country, plus the VAT number format and regex. Accepts ISO 3166-1 alpha-2 codes (DE, FR, IT, …); also covers non-EU European jurisdictions where available (NO, CH, GB, UA, TR, …). Use when the user asks "what is the VAT rate in X" or needs the VAT number format for a country. Free, no API key required.

Performs an offline syntactic check of a VAT number against the country-specific regex pattern. Does NOT verify the VAT with VIES — use validate_vat_number for that. Use when the user wants a quick sanity check on the shape of a VAT ID without burning a quota call. Free, no API key required.

Returns the list of countries the vatnode MCP server has VAT data for. Distinguishes EU member states (eligible for full VIES validation) from other European jurisdictions (rate lookup only).

Verifies an EU VAT number against the official VIES service and returns validity, company name, address, registration date and other metadata. When the requester (your own VAT) is configured on the vatnode account, also returns a VIES consultation number — audit-grade proof of validation. Use whenever the user wants to confirm a VAT is real, look up the company behind a VAT, or needs evidence for accounting/compliance. Requires a vatnode API key (free tier available). Only EU-27 + XI (Northern Ireland) are supported by VIES.
