## Why youtube_subscribe is rated Medium

Subscribing to a YouTube channel creates a new subscription relationship, which is a reversible write action (can be undone by unsubscribing). It does not delete data, execute code, or involve financial transactions. Misuse could cause an agent to subscribe to unintended channels on behalf of a user, but the blast radius is moderate since it is easily reversible.

From the tool's own definition: "Subscribe to a YouTube channel"

## Use case

AI agents use youtube_subscribe 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_subscribe": {
      "limits": [
        {
          "counter": "youtube_subscribe_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
