MCP tools · 5 exposed · ~1,142 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
check_vat_format ~176

Performs an offline syntactic check of a VAT number against the country-specific regex pattern. Read-only and offline: no network call, no API key, no rate limit, no side effects. Does NOT verify the VAT with VIES (a valid format does not mean the VAT is real or active) — use validate_vat_number for that. Output: { input, normalized, countryCode, validFormat (boolean), error }; countryCode is null when the prefix is unknown. 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.

NameTypeReqDescription
vatIdstringyesA VAT number, with or without spaces/dashes, with or without country prefix (e.g. "DE123456789", "IE 6388047 V").

get_country_vat_rates ~308

Returns the standard, reduced, super-reduced and parking VAT rates for a single European country, plus the VAT number format and regex. Read-only and offline: no network call, no API key, no rate limit, no side effects. Accepts ISO 3166-1 alpha-2 codes (DE, FR, IT, …); also covers non-EU European jurisdictions where available (NO, CH, GB, UA, TR, …). Output: { countryCode, countryName, vatName, vatAbbr, currency, standardRate, reducedRates[], superReducedRate, parkingRate, vatNumberFormat, vatNumberPattern, identifiers, updatedAt }; rates are percentages and may be null where not applicable. `identifiers` holds the names (not numbers) of the company registrar, the company register, the register number, the tax ID and the VAT ID, each keyed by language (every official language plus "en") or null, e.g. registryCodeName for FI is { fi: "Y-tunnus", sv: "FO-nummer", en: "Business ID" }. Returns an error if the country code is unknown. 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.

list_eu_vat_rates ~218

Returns current VAT rates for all EU member states (plus XI for Northern Ireland). Read-only and offline: no network call, no API key, no rate limit, no side effects. Takes no arguments. Output: { rates: Array<{ countryCode, countryName, vatName, vatAbbr, currency, standardRate, reducedRates[], superReducedRate, parkingRate, vatNumberFormat, vatNumberPattern, identifiers, updatedAt }>, count, updatedAt }. Rates are percentages (e.g. 25.5). `identifiers` holds the names (not numbers) of the company registrar, the company register, the register number, the tax ID and the VAT ID, each keyed by language (every official language plus "en") or null. 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.

list_supported_countries ~163

Returns every country the vatnode server has VAT data for (EU-27 + XI for Northern Ireland + ~17 other European jurisdictions such as NO, CH, GB, UA, TR). Read-only and offline: no network call, no API key, no rate limit, no side effects. Takes no arguments. Output: { countries: Array<{ countryCode, countryName, isEUMember, viesValidationSupported }>, count, euCount, updatedAt }, sorted by countryCode. `viesValidationSupported: true` means validate_vat_number can do live VIES verification; non-EU jurisdictions are rate-lookup only. Use to discover coverage or to pick a valid countryCode before calling get_country_vat_rates or validate_vat_number.

validate_vat_number ~277

Verifies an EU VAT number against the official VIES service and returns validity, company name, address, registration date and other metadata. The VIES consultation number (`consultationNumber`) is returned when a requester VAT is configured once in the vatnode dashboard Settings — a one-time account setup, not a per-call parameter. With a requester configured, every response is either a success with a non-null `consultationNumber` or an error; without one, `consultationNumber` is null and national-registry fallback stays enabled. Use whenever the user wants to confirm a VAT is real, look up the company behind a VAT, or needs evidence for accounting/compliance. Side effects: makes an authenticated network call to api.vatnode.dev (which queries the EU VIES service) and consumes one request from your monthly quota; it is read-only (verifies, never mutates) and safe to retry. Requires a vatnode API key (free tier available; set VATNODE_API_KEY). Only EU-27 + XI (Northern Ireland) are supported by VIES; other countries return an error.

NameTypeReqDescription
vatIdstringyesEU VAT number, with country prefix. Spaces and dashes are stripped. Examples: "DE123456789", "IE6388047V", "FR12345678901".
