Um programa verifica o servidor uma vez por dia: initialize e tools/list, sem modelo. Os tokens são o tamanho das definições, a cerca de quatro caracteres por token. A nota é a média de seis verificações do nome, da descrição, do esquema e das anotações de cada ferramenta; diz se as ferramentas estão bem descritas, não se funcionam. A nota pesa só o que foi medido: se responde (30%), se faz o trabalho do produto (25%), definições (20%), contexto (10%) e uso (15%). Uma parte não medida fica de fora, e uma instrução oculta limita a nota a 40. O estado dos servidores MCP dos fornecedores: método e números →

• list_monitors

  Find monitors in the organization by name, target, type, status or tag. Each row is short: id, name, type, target, status, is_active, tags, interval_seconds, ssl_expires_at and last_checked_at. Use it first to get a monitor's id, or to…

• list_tags

  List the tags used in the organization, most-used first, each with monitor_count and heartbeat_count, as items. Call it before tagging anything so you reuse an existing name instead of inventing a near-duplicate. Not a filter: to find the…

• get_monitor

  Read one monitor's full configuration and current state. It has type, target, interval_seconds, timeout_seconds, regions, config, status, is_active, confirmation_threshold, notification_cooldown_seconds, channel_ids (empty means every…

• create_monitor

  Create one monitor that checks a URL, host or port on a schedule from one or more regions, and return it in the get_monitor shape. Use check_target first to catch a typo or an unreachable host; use bulk_create_monitors for several…

• bulk_create_monitors

  Create 1 to 100 monitors in one call, all or nothing; for a single monitor use create_monitor. Requires a key with the write scope. An invalid item, or a batch that would exceed the plan, rejects the whole call and creates nothing: call…

• bulk_pause_monitors

  Pause up to 100 monitors in one call, all or nothing: no checks run and each open incident closes without an alert. Use it to stop monitoring a whole project or group found with list_monitors; for one monitor use pause_monitor, and to…

• bulk_resume_monitors

  Resume up to 100 paused monitors in one call, all or nothing; each goes back to PENDING and is checked on the next tick. For one monitor use resume_monitor; to run a check right away on a monitor that is already running, use check_now…

• bulk_update_monitors

  Set the same interval, timeout, regions, channels, threshold or cooldown on up to 100 monitors in one call, all or nothing. For example, move twenty PING monitors to other regions. Not for config or name (use update_monitor, one monitor…

• get_exposed_ports_preset

  List the ports that should never be reachable from the internet (databases, queues, admin panels). Returns ports, each a port number and the service that usually listens on it. Use it to pick ports when asked to watch a server for exposed…

• update_monitor

  Change one monitor's settings and return it in the get_monitor shape. Only the fields you pass change, and at least one besides monitor_id is required (422 otherwise); type and target never change (create a new monitor instead). Not for…

• pause_monitor

  Stop checking one monitor without deleting it: its status becomes PAUSED and an open incident on it closes without a recovery alert. Use it when the user wants a monitor off for an open-ended time. For a planned deploy or reboot prefer…

• resume_monitor

  Restart checks on one paused monitor: its status goes back to PENDING and it is checked on the scheduler's next tick. For many monitors use bulk_resume_monitors; to check a running monitor right away use check_now. Requires a key with the…

• delete_monitor

  Delete one monitor: it stops being checked and disappears from the organization's monitors, and no tool restores it. Use it only when the user explicitly asked for deletion; otherwise prefer pause_monitor, which keeps the monitor and its…

• check_now

  Queue one existing monitor to run on the scheduler's next tick instead of waiting out its interval, for example to confirm a fix. It returns the monitor record, not a check result: call get_monitor or list_check_results a moment later for…

• bulk_update_monitor_tags

  Add and/or remove tags across up to 300 monitors in one call, all or nothing: each monitor ends with (its tags | add) - remove. Use it to retag a fleet; to replace one monitor's whole tag list use update_monitor, to rename or drop a tag…

• get_uptime_summary

  Report one monitor's uptime percentage, average response time and incident count over the last 24 hours, 7 days and 30 days at once, to answer how reliable it has been. For a day-by-day series use get_uptime_daily; for response time per…

• get_plan_usage

  Show the organization's plan, its limits and current usage, to check that new monitors, heartbeats or regions fit before creating them or to explain a 403 naming a limit. Region codes and their cities come from list_regions; billing…

• list_incidents

  List the organization's monitor and heartbeat incidents, newest first, to see what is or was down and which alerts went out. Each item has id, monitor_id or heartbeat_id (exactly one is set), started_at, resolved_at (null while open)…

• acknowledge_incident

  Mark an open incident as being handled so its repeat alerts stop; the recovery alert still goes out when it resolves. Use it when someone is working on the outage. It does not close the incident (that happens when the monitor recovers)…

• list_heartbeats

  Find heartbeat (cron / dead-man's-switch) monitors. Each has id, name, state (PENDING until a success ping makes it UP or a /fail ping makes it DOWN; later UP, DOWN or PAUSED), period_seconds, grace_seconds, ping_url, last_ping_at…

• create_heartbeat

  Create a heartbeat: Fettle alerts when a scheduled job stops calling its ping_url. Use it for cron jobs, backups and workers that should report in; to probe a URL, host or port from outside use create_monitor. The job calls ping_url (GET…

• get_heartbeat

  Read one heartbeat in full, including how long its last run took. It has name, state, period_seconds, grace_seconds, ping_url, last_ping_at, last_success_at, last_start_at, last_duration_ms (how long the last run took, from its /start to…

• update_heartbeat

  Change one heartbeat's name, timing, channels or tags; only the fields you pass change. A new period or grace applies from the next ping: the current deadline (overdue_at) is not recomputed. To stop or restart late alerts use…

• pause_heartbeat

  Pause one heartbeat: it is no longer reported late, pings to its ping_url are accepted but ignored, and its open incident closes without an alert. Use it when the job is stopped on purpose, such as a runner taken out of service…

• resume_heartbeat

  Resume one paused heartbeat: it goes back to PENDING with no deadline, so it is not reported late until its next success ping restarts the clock. Use it once the job runs again; to change its timing use update_heartbeat. There is no bulk…

• delete_heartbeat

  Delete one heartbeat for good: its ping_url stops working (404) and no tool restores it. Use it only when the user asked for deletion; to stop alerts for a while use pause_heartbeat. Requires a key with the write scope. Returns…

• list_maintenance_windows

  List every maintenance window of the organization, enabled or not, in effect or not. Each has id, name, enabled, scope (ORG or MONITOR), dtstart, duration_minutes, rrule, timezone, monitor_ids and created_at. Use it to find a window's id…

  List the enabled maintenance windows in effect at this moment, to tell whether a monitor's alerts are silenced now. An ORG-scope window covers every monitor, a MONITOR-scope one its monitor_ids. For every window, including future and…

• get_maintenance_window

  Read one maintenance window with its schedule and its next three occurrences. It has the list_maintenance_windows fields plus next_occurrences, each with start and end. Use it to confirm when a recurring window fires next. To check a…

• create_maintenance_window

  Create a one-time or recurring maintenance window that silences alerts for some or all monitors. While a window is in effect its monitors keep being checked, but no incident opens and no alert goes out. Use it around a deploy or reboot…

• update_maintenance_window

  Change one maintenance window's name, schedule, scope or monitors, or switch it off with enabled false; only the fields you pass change. While a window is in effect its monitors keep being checked, but no incident opens and no alert goes…

• delete_maintenance_window

  Delete one maintenance window; alerts for its monitors resume at once and no tool restores it. To suspend a window but keep it, use update_maintenance_window with enabled false. Requires a key with the write scope. Returns {"success"…

• preview_maintenance_window

  Compute the next three occurrences, each with start and end, that a schedule would produce, without saving anything. Use it to check a recurring schedule before create_maintenance_window or update_maintenance_window; for a saved window's…

  List the organization's public status pages. Each has id, slug, name, description, is_published (publicly visible now), history_days, created_at, groups (each with name, position and its components) and ungrouped_components. Use it to…

• list_check_results

  List one monitor's individual check results, newest first, to find out why it is DOWN: which regions fail and with what status code or error. Each has id, region, checked_at, status, response_time_ms, status_code, error_message, details…

• get_response_time_by_region

  Chart one monitor's average response time over time, one series per region, to see where it is slow and since when. Returns monitor_id, window, bucket_seconds and regions, each with region, display_name and points (oldest first, the same…

• get_uptime_daily
