Sentinel

Sentinel checks your websites, APIs, DNS, TLS certificates, ports, heartbeats and cron jobs from four regions (Ashburn, Portland, Nuremberg, Singapore) and only calls something down when more than one region agrees. This connector puts your account in Claude.

Ask what is down right now and get the monitors that are failing, from which regions, and why. Ask what needs attention and get a prioritised list: open incidents, certificates about to expire, domains about to lapse, checks that have been slow. Pull performance history for a monitor, the DNS snapshots Sentinel has kept for it, or the list of incidents over any window. Check any public URL from all four regions on demand without creating a monitor.

On Pro and Business plans the connector can also act: create and update monitors, pause and resume them, run a check immediately, manage monitor groups, and open, acknowledge, resolve or delete incidents. Every write tool is annotated so Claude asks before anything destructive.

Sentinel is built and run by one person, and the connector is the same API the dashboard, CLI and Terraform provider use. Sign in with your Sentinel account over OAuth; no API key to paste. Free plan users get every read tool; write tools need Pro or Business.
