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.

The listing completeness score measures published information only. No safety or performance score has been assigned. A signature, source listing or successful HTTP response does not certify factual accuracy or safety.
