## Why list_voice_blocks is rated Low

This tool only reads/retrieves existing voice block metadata from a project. It has no side effects, does not execute code or commands, does not delete data, and does not affect financial transactions. It falls squarely into the Read category with low severity since misuse would only expose project data structure, not enable destructive or operationally damaging actions.

From the tool's own definition: "Tool description states 'List the project's voice blocks' — it retrieves and queries voice block data with audio status and assigned voices. No modifications, deletions, or external actions are performed."

## Use case

AI agents call list_voice_blocks to retrieve information from Framesail 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 Framesail:

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