Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| validate_vatA | Validate an EU or UK VAT number via VIES/HMRC. Returns validity, registered company name and address where the member state exposes them (Germany and Spain never do), a confidence level, and the upstream source. Accepts the number with or without country prefix (e.g. "DE123456789" or "123456789" + country_code="DE"). Greece: EL or GR both work. |
| validate_ibanA | Validate an IBAN (offline MOD-97 checksum) and resolve the bank name and BIC. Covers all SEPA countries. Accepts the IBAN with or without spaces. |
| validate_eoriB | Validate an EORI customs number (EU via EC, GB via HMRC, XI for Northern Ireland). |
| lookup_company_by_leiB | Look up company data (legal name, address, status) by LEI via GLEIF. |
| lookup_company_by_vatB | Look up company data by VAT number (GLEIF cross-reference). Useful as a fallback for German/Spanish VAT numbers where VIES returns no company name/address by law. |
| get_vat_ratesA | Get current VAT rates (standard/reduced) for an EU country by ISO 3166-1 alpha-2 code. |
| check_service_statusA | Check live health of upstream government services (VIES per-country, EORI, HMRC, GLEIF). Public endpoint — works without an API key. Use it to explain why a validation returned reduced confidence (e.g. Germany's VIES endpoint down). |

Scored across 7 tools
Most tools target distinct identifier types (IBAN, VAT, EORI, LEI, VAT rates, service status), but 'validate_vat' and 'lookup_company_by_vat' both accept VAT numbers and return company information, which could cause confusion. Descriptions help, but the overlap is real.
All tools use a consistent verb_noun pattern in snake_case (validate_*, lookup_company_by_*, get_*, check_*). The practice is uniform and predictable, making it easy for an agent to infer tool purpose from its name.
Seven tools is well within the ideal range for a domain-specific server. Each tool addresses a clear need (IBAN, VAT, EORI, LEI, VAT rates, and service status) without redundancy or bloat, making the set feel appropriately scoped.
The server covers the core European identifier validation landscape: bank accounts, VAT numbers, customs numbers, company lookup via LEI or VAT, VAT rates, and upstream service health. This is a complete surface for its stated purpose, with no obvious dead ends or missing critical operations.
