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.

get_public_holidaysread-only Full list of official public holidays for a country in a given year. Use for "what are the holidays in Germany in 2026", planning around a country's holiday calendar, or any "list the holidays for X" question. `country_code` is a 2-letter ISO code (US, GB, DE, FR, JP, ...) -- roughly 100 countries are covered, not every country worldwide. Returns each holiday's date, local name, English name, and type (e.g. Public, Bank, Observance).

is_public_holidayread-only Checks whether one specific date is a public holiday in a country, and names it if so. Use for "is Dec 25 2026 a holiday in the US", "is the office closed on this date", or any single-date holiday check -- prefer this over `get_public_holidays` when the question is about just one day. `country_code` is a 2-letter ISO code; `date` is YYYY-MM-DD. Returns whether it's a holiday and, if so, its name.

Schemas: list_tools.
