Validates EU VAT numbers: local format/checksum for 27 states + XI, then VIES (cached 24 h).
Scored across 2 tools
The two tools have clearly distinct purposes: validate_vat validates VAT numbers, while agent_readiness_check grades MCP/x402/tool manifests. An agent should not confuse these operations.
Both names use snake_case, but only validate_vat follows a clear verb_noun pattern. agent_readiness_check is a noun phrase, making the naming convention mixed despite being readable.
Only two tools are exposed, and agent_readiness_check is unrelated to the server's stated VAT validation purpose. For this narrow domain, the extra tool does not earn its place and makes the set feel poorly scoped.
validate_vat appears thorough for single-number EU VAT validation, including local format/checksum checks, live VIES queries, caching, and name/address matching. Bulk validation or additional VAT workflow tools are absent, but the core validation lifecycle is well covered.
Deterministically grade an MCP tool catalog or a third-party x402 endpoint. Provide exactly one of: mcp_url (public https MCP server; initialize + tools/list), x402_url (public https resource; the gateway requests it WITHOUT an X-PAYMENT header and reads the 402), or tools (a JSON tool manifest). Never pays or signs a payment. No LLM is used. Requires an API key in Authorization: Bearer or X-Api-Key.
Inputs: tools, mcp_url, x402_url.
Validate an EU VAT number (27 member states + XI Northern Ireland). Normalizes the input, checks the national format and checksum locally, then queries VIES (European Commission) live with limited retries. status: valid | invalid (local checksum/format failed, or VIES answered valid=false) | unverified_ms_down (the member state system is down) | unverified. Results are cached across instances to respect VIES rules: valid/invalid 24 h, unverified 10 min; checked_at = time of the original VIES check, cache_age_s = its age in seconds. Never returns invalid because VIES is unavailable. The VIES name/address are never returned: pass your own name and/or address to get name_match / address_match booleans, computed locally (not sent to VIES; null when VIES has no data). Requires an API key in Authorization: Bearer or X-Api-Key. Controllo automatico: regole locali di formato e checksum più una consultazione live del VIES (Commissione europea). Non è un'attestazione fiscale né una consulenza legale; i dati VIES provengono dalle banche dati degli Stati membri. Conserva una tua traccia della consultazione VIES. / Automated check: local format/checksum rules plus a live query of VIES (European Commission). Not a tax attestation and not legal advice; VIES data come from the member states' databases. Keep your own record of the VIES consultation. / Automatische Prüfung: lokale Format- und Prüfziffernregeln plus eine Live-Abfrage von VIES (Europäische Kommission). Keine steuerliche Bescheinigung und keine Rechtsberatung; die VIES-Daten stammen aus den Datenbanken der Mitgliedstaaten. Bewahren Sie einen eigenen Nachweis der VIES-Abfrage auf.
