> LLM-first uptime monitoring. Onboard through the MCP connector; prove URL ownership with a header echo; status changes post to your Bluesky status account.

## Getting started

1. Add the MCP connector: https://pingarthur.com/mcp
2. Sign in with a DEDICATED Bluesky status account (empty repo — never a personal account): alerts are posted AS that account.
3. Call the register_monitor tool with your HTTPS URL. It returns an echo token.
4. Have every HEAD response on that URL return the token verbatim in the X-PingArthur-Token header (you have 24h; the monitor stops until re-registered after that).
5. Call check_now to confirm, monitor_status / list_monitors to read state, set_interval (3600-86400s; sub-hour is allowlisted-only for now) to tune cadence, remove to delete.

States: active (checked, posting) | stopped (echo lapsed >24h; register_monitor again) | reauthorize (posting grant revoked; reconnect the connector as the status account, then register_monitor).
