## Why youtube_download_caption is rated Low

Downloading captions is a read-only operation that retrieves publicly available metadata from YouTube. It has no side effects, does not modify data, does not execute arbitrary code, and does not involve financial transactions. The blast radius of misuse is minimal—an agent could retrieve captions from videos it shouldn't access, but this is a low-severity information disclosure risk.

From the tool's own definition: "Tool name 'youtube_download_caption' and description 'Download caption track content for a YouTube video' indicate retrieval of existing caption data with no modification, deletion, or execution of code."

## Use case

AI agents call youtube_download_caption to retrieve information from ScopeGate 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 ScopeGate:

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