Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (2)

`validate_vat`	Validate a single EU VAT number. Costs 1 credit unless upstream is unavailable and there's no cache (then it's free and honest about it). Args: country_code: 2-letter EU member state code (e.g. DE, FR, EL, XI). vat_number: The VAT number without the country prefix.
`validate_vat_batch`	Validate up to 50 EU VAT numbers in one call. 1 credit per item that gets a real answer (unavailable_upstream items are free). Args: items: list of {"country_code": str, "vat_number": str}, max 50.

Schemas: list_tools.
