## Tools (as reported by the server, not verified)

- `check\_website`: Use when a public website will not load or you need a fresh server-side availability observation. Returns HTTP status, DNS answers, redirect chain, HTTPS connection evidence, timestamps and bounded retry attempts. Blocked or inconclusive is not proof of a global outage. No API key. API/MCP share cac
- `get\_service\_status`: Read the latest scheduled homepage observation and up to 12 recent samples for a curated service. Includes freshness, scope and the official status link. Does not make a new request to the target website. Scheduled about every 15 minutes; stale after 35 minutes. Not an official or global outage repo
- `list\_monitored\_services`: Discover curated service IDs, homepage URLs, measurement scopes and official status dashboards. No new website probe. Use get\_service\_status for existing observations or check\_website for any public hostname.
- `get\_provider\_incidents`: Use for official active incident reports from Claude, OpenAI, Google Cloud, Google Workspace, Google Search, Cloudflare, GitHub or Wikimedia. Returns affected components where reported, source links, updates, retrieval timestamps and explicit availability/staleness. Missing or stale data is unknown,
- `investigate\_incident`: Use when a public endpoint fails and you need evidence-based next steps. Combines one protected HTTP/DNS check, existing homepage history where supported, and optional official provider incidents. Provider is inferred only for known provider-owned hostnames; pass provider for a known dependency of a

Supported: Claude, OpenAI, Cloudflare, GitHub, Wikimedia. Optional component accepts an exact ID or case-insensitive name substring; no match is unknown, never operationa
- `check\_dns`: Use for public-domain DNS diagnosis: compare A/AAAA/CNAME/NS/MX/TXT/CAA records, TTL, DNS response codes and resolver-reported DNSSEC AD.
