unity_asset_delete

THE RISK

Critical Risk

Deletion of project assets cannot be undone and permanently removes data. This is a destructive operation with high blast radius: an AI agent invoking this tool without proper safeguards could permanently erase important game assets, scripts, models, or other project files. While not as critical as a full project wipe, the irreversibility and potential for significant project damage justify high severity.

From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete an asset from the project' — this is an irreversible removal of data from a Unity project.

HOW TO CONTROL UNITY_ASSET_DELETE

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_asset_delete:

policy.json

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

unity_asset_delete 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.
