VIES VAT Validation + ChatGPT

Validate EU VAT numbers via the European Commission VIES (VAT Information Exchange System) REST API. Confirms that a VAT number is registered for intra-Community trade and returns the trader name and address when the member state exposes them.

Requisitos previos

Las instrucciones de configuración completas están incluidas en el conector (visibles en el store al seleccionarlo). Las variables de entorno requeridas:

(none — public API)

Paso 1 — Obtener credenciales

Use for B2B invoice compliance: before issuing an intra-EU invoice without VAT, confirm the buyer's VAT number is valid via this adapter.

Country codes: ISO 3166-1 alpha-2, plus EL for Greece and XI for Northern Ireland. Common codes: DE, AT, FR, IT, ES, NL, BE, PL, DK, SE, FI, IE, PT, CZ, HU, RO.

Format: VAT number must NOT include the country code prefix (e.g. for DE123456789 pass countryCode='DE' and vatNumber='123456789').

Response: valid: true/false, plus name and address when provided by the member state. Some countries (DE, ES) do not return name/address for privacy reasons — in that case only valid is authoritative.

…(continued in the in-app connector instructions)

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d
