WHAT IT DOES

What delete_object does on BlenderMCP

AI agents call delete_object to permanently remove resources in BlenderMCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_object is rated Critical

Deletion of scene objects in Blender cannot be undone by the tool itself (undo would require separate action). While the blast radius is limited to a single 3D project file rather than critical infrastructure, the action is irreversible and destructive in nature. An AI agent could accidentally or maliciously remove important 3D assets, requiring manual restoration.

From the tool's definition Tool name is 'delete_object' and description states 'Delete an object from the scene' — the verb 'delete' combined with removal from a scene constitutes irreversible data destruction.

RECOMMENDED RULE

The rule that runs delete_object safely

PolicyLayer is an MCP gateway: it sits between your AI agents and BlenderMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_object, this is the rule to start with:

delete_object Hidden

delete_object is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.

The button opens the PolicyLayer dashboard: create your workspace, connect BlenderMCP, apply this rule, and every delete_object call is checked against it from then on.

Register the Blender MCP server in PolicyLayer and add a rule for delete_object: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches BlenderMCP. Nothing to install.

What risk level is delete_object? +

delete_object is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit delete_object? +

Yes. Add a rate_limit block to the delete_object rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block delete_object completely? +

Set action: deny in the PolicyLayer policy for delete_object. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
