Categories and declared capabilities
Topic categories are derived from publisher text for discovery, not independently verified capabilities.
The registry does not provide a verified tools list. See the observations, when available, for any tools/list check; a published tools list does not establish that execution succeeds.
Evidence, with its limits.
This listing is indexed. Any domain claim or endpoint observation appears separately with its date and limited scope. No payment execution, factual accuracy or safety certification is inferred.
