## Findings

- **info** The word "credentials" in `create_heartbeat` ([credentials-mention](https://anlyon.dev/methodology#credentials-mention))

```untrusted-server-text
The description mentions "credential".

description: "...status page; the secret key is the only credential — keep it."
```


## Changes things (2)

Creates or changes something that can be changed back. Claude Code: ask.

### `create_heartbeat`

- The name "create_heartbeat" says "create": a word for a change.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
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 credential — keep it.
```

### `record_failure`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `get_status`

- The name "get_status" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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.
```

### `list_heartbeats`

- The name "list_heartbeats" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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 the result.
```

### `ping_heartbeat`

- The name "ping_heartbeat" says "ping": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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"} objects instead — alerts fire on trusted->challenged / recovery transitions only.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `golemreach-heartbeat`:

    ],
    "ask": [
      "mcp__golemreach-heartbeat__create_heartbeat",
