| remote | auth | reachable | uptime 30d | p50 | protocol | last ok |
|---|---|---|---|---|---|---|
https://watchpup.watchpup.workers.dev/mcp streamable-http | none | no (9 failures) | 77% | 157 ms | 2025-06-18 | 2026-09-30 |
ack_incident | Mark an ongoing incident as "someone is on it" — pauses still-down reminder alerts for that monitor until recovery. Set un=true to un-acknowledge (re-arms reminders). |
add_incident_note | Attach/replace a note (max 500 chars) on an incident. Notes publish with the incident on public status pages, their JSON and the Atom feed. Empty string clears. |
check_urlread-only | Check any public URL RIGHT NOW: is it up, HTTP status, response time in ms. With kind:"mcp" it instead performs a real JSON-RPC initialize handshake against a streamable-HTTP MCP server endpoint and reports the server’s self-declared name/version/protocol — useful to tell "the MCP server is down" from "my client is misconfigured". Works without an API key (rate limit 30/hour per IP). For continuous monitoring with alerts, use create_monitor. |
create_monitor | Create a monitor. kind=http (needs url), tcp (target "host:port"), tls (target host[:port] — cert-expiry watch), domain (target — registration-expiry via RDAP), dns (target + rtype A/AAAA/MX/... , optional expect_value), heartbeat (dead-man’s switch for cron jobs/agent loops: needs name; response includes ping_url to curl from the job, and a ping_email address). Common options: name, interval (seconds, min 60), tags. http options: expect ("2xx,301"), keyword, keyword_absent:"absent", slow_ms (number or "auto"), method, headers, body, json_path/json_expect, header_name/header_expect. heartbeat options: grace (seconds), cron ("0 3 * * *") + tz, max_duration_s. Any other documented field (see /llms.txt) also works — extra properties are passed through. |
delete_monitordestructive | Permanently delete a monitor and all its check history, events and rollups. Cannot be undone. |
get_accountread-only | Who am I: account email, monitor count/limit, plan limits. Good first call to verify the API key works. |
get_monitorread-only | Full detail for one monitor: status, config, 24h latency percentiles and trend (http/tcp), SLA budget if a target is set. Heartbeat monitors include their ping_url and ping_email. |
get_status_pageread-only | Machine-readable state of any public Watchpup status page by slug: per-monitor status, uptime, incidents last 30d. No API key needed. |
list_channelsread-only | Alert delivery channels on the account (email / webhook / Discord / Slack / ntfy / Telegram), their verification state and delivery health. |
list_incidentsread-only | Downtime incidents (ongoing and resolved) across all monitors: start, duration, cause, acknowledgement, notes. |
list_monitorsread-only | List all monitors on the account: current up/down status, kind, target, interval, last check. Optionally filter by tag. |
update_monitor | PATCH any monitor field: name, url, target, interval, expect, keyword, slow_ms, grace, cron, tags, sla_target, renotify, channels (alert routing)... Pause with {"status":"paused"}, resume with {"status":"new"}. Empty string clears optional fields. |
