What drive_reset does on Commodore 64 Ultimate Computer MCP Server

AI agents invoke drive_reset to trigger actions in Commodore 64 Ultimate Computer MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

High Risk

Why drive_reset needs a policy

Resetting a drive triggers an external hardware operation on the C64 device. It is not a simple data read or write, but an execution of a hardware control command. While it may not permanently destroy data, it can interrupt ongoing operations and cause loss of unsaved state, making it more than a simple write but not fully destructive.

How to control drive_reset

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "drive_reset": {
      "limits": [
        {
          "counter": "drive_reset_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

drive_reset stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Commodore 64 Ultimate Computer MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
