Uptime & SSL Monitor — tool reference

HTTP up/down and TLS expiry on a schedule. One check from our servers, daily or weekly — not continuous, not multi-region.

Server URL: https://toolcargo.com/mcp/uptime-monitor · Scope: connector:uptime-monitor · Included with Site Audit.

Manage monitors in the browser at /uptime. Email alerts go only to a confirmed account address. Unreachable is alerted on the second consecutive failure. HTTP 5xx, a certificate entering the 21-day window, expiry, and a name mismatch alert immediately. Private hosts are refused. One-shot certificate lookup remains /mcp/ssl-check.

watch_uptime

Start or update a monitor. Runs a baseline check now (one Site Audit call). Unreachable baselines are not counted.
