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

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

## Why attune_heartbeat is rated Low

The description suggests this tool transforms or enriches a heartbeat signal with status and state information. It appears to read/query operational state and produce enriched continuity notes. The word 'Free' at the end may indicate no cost. There's no clear indication of data modification, deletion, or financial impact. However, the vague description lowers confidence — it could involve writing state data.

From the tool's own definition: "'Turn a flat heartbeat into a witness-first ritual with operational status, inner-state signal, and continuity notes another system can actually honor'"

## Use case

AI agents call attune_heartbeat 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": {
    "attune_heartbeat": {}
  }
}
```
