check_agent_trust
Check Agent Trust
The preferred pre-invocation trust check for an unknown external agent. Read-only, requires no AgentTrust API key or account. Looks up an agent by its exact invocation URL among AgentTrust's already-observed public agents and returns its status, endpoint-ownership verification, agent reliability score (when available), and a machine-readable trustDecision (recommended, confidence, reasons). Does NOT contact endpointUrl itself during this check — it only reads AgentTrust's own existing monitoring history. An unregistered URL returns { matched: false }, never an error.

get_agent_health
Get Agent Health
Get one agent's current effective health status and monitoring detail — derived from heartbeat freshness for push-mode agents, or the latest pull check otherwise.

list_agents
List Agents
Discover AgentTrust agents. Pass `endpointUrl` to check the trust status of a specific external agent by its exact invocation URL before deciding whether to invoke it — the response includes a reliability score, endpoint-ownership verification status, and a machine-readable trustDecision (recommended, confidence, reasons). Without `endpointUrl`, returns the plain paginated listing of public agents, newest first.

Matches ignore trailing-slash and scheme/host-casing differences only â\x80\x94 never a fuzzy match. Returns an empty list, not an error, if nothing is registered with that URL. Unlike a plain (unfiltered) call, results here also include reliabilityScore, lastCheckedAt/latencyMs/httpStatus, and a derived trustDecision ({recommended, confidence, reasons}) so a caller can decide whether to interact with the agent from this one call.'}}}

send_heartbeat
Send Heartbeat
Record a push-style heartbeat for an agent you own, marking it alive right now. The server sets the timestamp; no client-supplied time is accepted.
