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

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

## Why get_master_spectrum is rated Low

The tool appears to retrieve or query spectral information from Ableton Live's master output without side effects. No arguments are indicated that would allow code execution, data modification, or destructive operations. The main uncertainty stems from the empty description, which slightly lowers confidence, but the naming pattern and context strongly suggest read-only retrieval of audio analysis data.

From the tool's own definition: "Tool name 'get_master_spectrum' indicates retrieval of spectral analysis data from the master channel. No description provided, but the 'get_' prefix and sibling tools (analyze_composition, analyze_harmony, analyze_for_automation) suggest querying/reading…"

## Use case

AI agents call get_master_spectrum to retrieve information from Livepilot 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 Livepilot:

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