WHAT IT DOES

What youtube_subscribe does on ScopeGate

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.

RISK

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.

RECOMMENDED RULE

The rule that runs youtube_subscribe safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ScopeGate, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For youtube_subscribe, this is the rule to start with:

youtube_subscribe Rate-limited

youtube_subscribe stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ScopeGate, apply this rule, and every youtube_subscribe call is checked against it from then on.
