Dead-man switch for AI agents & cron jobs: heartbeat with state capsule, alerts + resume links

Model Context Protocol (MCP) Server: ai.aislabs/recorder

The ai.aislabs/recorder MCP server provides a “dead-man switch” mechanism for AI agents and cron jobs. It performs a heartbeat with a state capsule, and can trigger alerts with resume links. It is designed to help monitor liveness and support continuation after interruptions.

🛠️ Key Features

Dead-man switch for AI agents & cron jobs
Heartbeat signaling with state capsule
Alerts plus resume links

🚀 Use Cases

Monitoring AI agents for liveness
Tracking cron job execution and detecting failures
Enabling resumption using provided resume links

⚡ Developer Benefits

Clear failure detection via heartbeat
Structured state capsule for context
Automated alerting with resume targets

⚠️ Limitations

Server metadata available does not specify the exact tools or interfaces behind the stated behavior (toolCount: 5).

Captured live from the server via tools/list.

register_monitor

Agent Flight Recorder — FREE (1 monitor per alert target) / Gateway key (20 monitors + stored capsules + fleet view). Register an agent or scheduled job to be watched: you get a monitor_id + secret; the agent then calls heartbeat every period_minutes. If heartbeats stop for period + grace, the alert target (Discord/HTTPS webhook and/or email) is notified with the last state capsule and a resume link.

Parameters5

name	string	required	What is being watched, e.g. "nightly ETL loop"
period_minutes	number	optional	Expected heartbeat interval in minutes (default 10)
grace_minutes	number	optional	How late a heartbeat may be before alerting (default 5)
alert_webhook	string	optional	Discord webhook URL or any HTTPS webhook (receives JSON)
alert_email	string	optional	Email address to alert (Gateway key tier only; capped at 10 emails/monitor/day)

heartbeat

Agent Flight Recorder — "still alive" ping for a registered monitor. Include capsule (any JSON ≤32KB: current step, done, next, ids) so a dead-man alert can carry resume state (stored on the key tier). status:"fail" reports a failure immediately.

Parameters4

monitor_id	string	required
secret	string	optional	Monitor secret from register_monitor (not needed when calling with the owning Gateway key)
capsule	object	optional	Resume state: { step, done: [...], next, ids: {...} } — anything JSON
status	string	optional

    "monitor_id"
  ],
  "additionalProperties": false
}

fetch_capsule

Agent Flight Recorder (Gateway key) — get the last state capsule a monitored agent sent, to resume from where it died.
