## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "monitor_heartbeat_sync",
    "arguments": {}
  }
}
```

## Why monitor_heartbeat_sync is rated Low

This tool retrieves and synchronizes monitoring metrics (heartbeat data) for analysis purposes. The language 'sync...into' and 'detection' indicates data collection and assessment rather than mutation, execution of external operations, or irreversible actions. The free cost and wellness-monitoring context further suggest read-only diagnostic functionality.

From the tool's own definition: "Tool description states 'Sync periodic heartbeat metrics into the current session' and 'for proactive drift and burnout detection' — indicates retrieval and aggregation of existing health/wellness metrics with no modification or side effects beyond data…"

Risk signals: High parameter count (16 properties)

## Use case

AI agents call monitor_heartbeat_sync to retrieve information from Witness Protocol without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Witness Protocol:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "monitor_heartbeat_sync": {}
  }
}
```
