Scored across 2 tools
The two tools have clearly distinct purposes: one validates a VAT number, the other lists supported country codes. There is no overlap or ambiguity in their functionality.
Both tools follow a consistent verb_noun pattern (check_vat, list_supported_countries). The naming is predictable and uniform.
With only two tools, the server is minimal but appropriately scoped for its narrow purpose of VIES VAT validation. It is slightly thin but each tool earns its place, so it is reasonable.
The tool surface fully covers the domain: checking VAT numbers (with optional consultation number for legal proof) and listing supported countries. No obvious gaps exist for the intended use case.
