Cert Countdown

When a TLS or SSL certificate crosses the 14-day-to-expiry line, this agent pings the on-call room. The ping carries the hostname, the issuer, the exact expiry date and time, and the days remaining, so the renewal happens on a calm Tuesday instead of during a 2am outage. Feed it from a cron job that checks your certs and POSTs the ones nearing expiry, from your monitoring tool's webhook, or by pointing an MCP client at it. Anything that can send an HTTP request, webhook, or MCP call keeps the countdown honest. Expired certs take down checkout pages and APIs with no warning and a red browser screen. This agent turns that cliff into a two-week heads-up. Operated by PingRoom.
