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

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

## Why start_recording is rated High

This falls under Execute rather than Read because it actively initiates a hardware operation (microphone recording) rather than merely querying or retrieving existing data. It is not Destructive, Write, or Financial.

From the tool's own definition: "The tool 'start_recording' triggers an external operation (audio capture from hardware) whose effects depend on runtime conditions and subsequent agent actions."

## Use case

AI agents invoke start_recording to trigger actions in Voice Recorder MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Voice Recorder MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "start_recording": {
      "limits": [
        {
          "counter": "start_recording_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
