## Why youtube.channel_details is rated Low

This tool retrieves publicly available information about YouTube channels. It performs a query operation with no side effects—no data is created, modified, deleted, or altered. The information returned (channel metadata, counts, images, links) is read-only access to public information.

From the tool's own definition: "Tool description uses 'Fetch metadata' and 'Returns title, username, description, subscriber and view counts, join date, verification flags, avatar and banner images, keywords, and external links.' These are all retrieval operations on public YouTube channel…"

## Use case

AI agents call youtube.channel_details to retrieve information from Vee3 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 Vee3:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "youtube.channel_details": {}
  }
}
```
