## Why spotify_get_audio_features is rated Low

This tool queries Spotify's API to fetch immutable track metadata. It does not create, modify, delete, execute code, or perform financial operations. The data returned is read-only analytical information about a track's properties. There is no blast radius from misuse beyond potentially unauthorized data access, which is mitigated by typical API authentication.

From the tool's own definition: "Tool performs a GET operation to retrieve audio analysis metadata (danceability, energy, tempo, etc.) for a Spotify track."

## Use case

AI agents call spotify_get_audio_features to retrieve information from UnClick 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 UnClick:

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