## Why youtube_add_comment is rated Medium

This tool creates new data (a comment) on YouTube, which is reversible (comments can be deleted by the user or removed by moderation). It does not execute arbitrary code, delete data irreversibly, or move money.

From the tool's own definition: "Tool name is 'youtube_add_comment' and description states 'Add a comment to a YouTube video'. The 'add' verb and action of creating new content (a comment) on a third-party platform classifies this as a Write operation."

## Use case

AI agents use youtube_add_comment to create or update resources in ScopeGate, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ScopeGate environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches ScopeGate:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "youtube_add_comment": {
      "limits": [
        {

        }
      ]
