unity_hub_install_editor

THE RISK

High Risk

This tool installs software onto the host system, which triggers an external operation (downloading and installing Unity Editor binaries and platform modules). It is not purely a write operation — it executes system-level installation processes with significant side effects including disk usage, system configuration changes, and potentially long-running downloads.

From the tool's definition Install a specific Unity Editor version. Optionally include platform modules (android, ios, webgl, linux, macos, windows-il2cpp).

HOW TO CONTROL UNITY_HUB_INSTALL_EDITOR

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "unity_hub_install_editor": {
      "limits": [
        {
          "counter": "unity_hub_install_editor_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

unity_hub_install_editor 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.

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