WHAT IT DOES

What duplicate_object does on Blender Copilot MCP Server

AI agents use duplicate_object to create or update resources in Blender Copilot MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Blender Copilot MCP Server environment.

RISK

Why duplicate_object is rated Medium

This tool creates new scene data (a duplicate object) which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. While duplication could inflate scene complexity or consume resources, the primary action is data creation/modification that can be undone in Blender's undo system.

From the tool's definition Tool name 'duplicate_object' and description 'Duplicate an object' indicates creation of a new object in the 3D scene. The 'linked=True' option that 'shares mesh data (instance)' describes a reversible creation variant.

RECOMMENDED RULE

The rule that runs duplicate_object safely

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

duplicate_object Rate-limited

duplicate_object stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",

    "duplicate_object": {
      "limits": [
        {
          "counter": "duplicate_object_rate",

          "max": 30,

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Blender Copilot MCP Server, apply this rule, and every duplicate_object call is checked against it from then on.

Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Blender Copilot MCP Server. Nothing to install.

What risk level is duplicate_object? +

duplicate_object is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit duplicate_object? +

Yes. Add a rate_limit block to the duplicate_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 duplicate_object completely? +

Set action: deny in the PolicyLayer policy for duplicate_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.

What MCP server provides duplicate_object? +
