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 (3)

check_feature_supportread-onlyCan I use this feature, and from which browser version? Accepts a loose name (":has()", "container queries", "css-grid") and resolves it to a caniuse feature, then returns the earliest continuously-supported version per major browser, global usage percentage, and a conservative safe_to_use flag. Use this first; it answers the whole question in one call.
get_feature_by_idread-onlySupport table for an exact caniuse feature id. Use when the id is already known, for example from a previous search. No fuzzy matching is applied.
search_featuresread-onlyFind the caniuse feature id for a loose query. Use when a query is ambiguous and you want to choose between candidates before checking support.

Schemas: list_tools.
