Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (5)

check_certificateread-onlyReads the HTTPS certificate of a public domain and reports days until expiry, the expiry date and the issuer.
check_siteread-onlyLive up/down check of any public website from an independent server (Singapore; Boston for sites that geo-block Singapore). Returns a one-sentence verdict plus status code, latency, resolved IP, redirect target, the view from the other region when available, and how many users reported problems in the last hour. Results are cached 30 s per domain.
list_monitored_sitesread-onlyThe 634 sites checked every 5 minutes, grouped in 17 categories. Without arguments returns the category list with counts; filter by category or a text query to get domains (at most 200 per call).
list_outagesread-onlyLists the monitored sites (634 across 17 categories) that are confirmed down right now: two consecutive failed checks from their home region and no other region seeing them up in the last 15 minutes. Optional category filter.
site_historyread-onlyUptime percentage over 24 h and over the requested window (up to 7 days), the list of outages in that window, when the site was last seen down, the current state and user-report counts. Only for monitored sites (see list_monitored_sites); use check_site for anything else.

Schemas: list_tools.
