unity_prefab_remove_component

THE RISK

Critical Risk

Removing a component from a prefab asset is an irreversible destructive operation — it permanently deletes the component and its data from the prefab. This affects all scene instances using the prefab and cannot be trivially undone without version control. The blast radius is high as it can break all prefab instances across an entire Unity project.

HOW TO CONTROL UNITY_PREFAB_REMOVE_COMPONENT

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_prefab_remove_component:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "unity_prefab_remove_component"
  ]
}

unity_prefab_remove_component disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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.
