Why ultimate_turn_drive_on needs a policy

This tool activates/enables a hardware drive, which is a state change (turning something on) that is reversible (it can be turned off again). It falls under Write as it modifies the state of a device. It does not delete data, execute code, or involve financial transactions. Severity is medium because misuse could cause unintended hardware behavior on a physical Commodore 64 Ultimate device.

POLICY

How to control ultimate_turn_drive_on

PolicyLayer is an MCP gateway — it sits between your AI agents and Commodore 64 Ultimate MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for ultimate_turn_drive_on:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ultimate_turn_drive_on": {
      "limits": [
        {
          "counter": "ultimate_turn_drive_on_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

ultimate_turn_drive_on 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.
