disconnectFromServer

THE RISK

Low Risk

Why disconnectFromServer needs a policy

This tool terminates a connection to a Minecraft server. It doesn't read data, write/create data, execute code, delete data irreversibly, or involve financial transactions. It simply ends a network session, making it an 'Other' category action. The blast radius is low — an AI misusing this would at worst drop the current session, which is easily re-established via connectToServer.

POLICY

How to control disconnectFromServer

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Minecraft Remote, and nothing reaches the server without passing your rules. This is the rule we recommend for disconnectFromServer:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "disconnectFromServer": {
      "limits": [
        {
          "counter": "disconnectfromserver_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

disconnectFromServer gets a rate cap, and everything else on the server is denied unless you say otherwise.
