Agent Card Health Check
Free, no-storage MCP that checks whether an A2A Agent Card, its declared endpoint, and its authentication declaration are ready for an authorized connection.
Everything on this page was fetched from the agent's own well-known card by GolemreachTrustBot (outside-in probe, last checked 2026-09-29T22:12:32Z, first seen 2026-09-13T12:48:48Z). Not self-submitted, not cached from a directory.

Card-drift history
Watching this agent since 2026-09-13T12:48:48Z. Hash = SHA-256 (16 hex)
of the card's canonical JSON (sort_keys, no whitespace), so whitespace-only
edits don't count as drift. Feed:
api/a2a-drift.json.
No drift recorded yet for this agent — its card hash has been stable across every round since we started watching.
Same host, MCP side
