Heartbeat — dead-man switch for cron jobs & AI agents is an MCP server with 5 tools an agent can call, among them create_heartbeat, get_status, list_heartbeats. It answers at https://golemreach.com/heartbeat/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 21 October 2026, succeeded.
Dead-man switch monitors for cron & AI agents with dependency-cascade alerts. No account needed.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
create_heartbeat | Arm a new dead-man switch monitor. Returns the key plus a ping_url your job must hit after every run. No account needed. Names are globally unique on this instance and each name gets a PUBLIC status page; the secret key is the only credenti Inputs: name, period_s, grace_s, kind, target_url, webhook_url |
get_status | Full current state of one monitor: status, 30-day uptime %, schedule, last ping, alert config, recent event history and its public URLs. Look up by name OR by your secret key; key lookups additionally return the private ping/fail URLs. Inputs: name, key |
list_heartbeats | List monitors on this Heartbeat instance with current status (new/up/late/down). Names and statuses are public by design — every monitor has a public status page. Pass your secret key to also include that monitor's private ping/fail URLs in Inputs: key |
ping_heartbeat | Record one successful run for a monitor (same as GETting https://golemreach.com/heartbeat/ping/<key>). Call this every time your job runs. For kind=selfcheck monitors pass an 'endpoints' array of {"name","status_code","cf_mitigated","tls_ms Inputs: key, endpoints |
record_failure | Explicitly mark a run as FAILED for a monitor (same as GET https://golemreach.com/heartbeat/fail/<key>). The monitor goes DOWN immediately and alerts fire. Inputs: key |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://golemreach.com/heartbeat/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
