What delete_objects does on GOLEM-3DMCP-Rhino-

AI agents call delete_objects to permanently remove resources in GOLEM-3DMCP-Rhino- — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

Critical Risk

Why delete_objects needs a policy

Deletion of objects in a Rhino document cannot be undone programmatically through the MCP interface and represents permanent data loss. While Rhino itself has an undo feature, an AI agent invoking this tool in error would cause immediate loss of user work. This fits the Destructive category definition: irreversibly deletes data.

From the tool's definition Tool name is "delete_objects" and description states it will "Delete one or more objects from the Rhino document." This is an irreversible operation that removes data permanently.

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

How to control delete_objects

PolicyLayer is an MCP gateway — it sits between your AI agents and GOLEM-3DMCP-Rhino-, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_objects:

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_objects"
  ]
}

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

  1. Create a free account and register GOLEM-3DMCP-Rhino- — 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.
