前提条件

完全なセットアップ手順はコネクタ自体に組み込まれています (ストアでコネクタを選択すると表示)。必要な環境変数:

(none — public API)

ステップ 1 — 認証情報を取得

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.

ステップ 2 — アダプターをインストール

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

ステップ 3 — Gemini にコネクタを追加

    }
  }
}
