## Why list_models is rated Low

The tool retrieves and queries static model information without creating, modifying, deleting, or executing any operations. It is purely informational, used to help users understand available options before choosing a model. This has negligible security impact.

From the tool's own definition: "Tool name is 'list_models' and description explicitly states it 'Lists available TTS models' and 'Returns: model list with capabilities.' This is a read-only query operation with no side effects."

## Use case

AI agents call list_models to retrieve information from ElevenLabs MCP Enhanced 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)
