What connectToServer does on MCP Minecraft Remote

AI agents invoke connectToServer to trigger actions in MCP Minecraft Remote. 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.

Why connectToServer needs a policy

Initiating a connection to a remote server is an external operation that establishes a live session, enabling all subsequent control actions (navigation, building, mining, chat, etc.). It is not a simple read and has significant blast radius since a successful connection grants an AI agent full remote control over a Minecraft player on a server, potentially affecting other players and server state.

Documented attack patterns abuse exactly the kind of access connectToServer gives an agent:

How to control connectToServer

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 connectToServer:

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

connectToServer 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 MCP Minecraft Remote — 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.
