What set_object_layer does on GOLEM-3DMCP-Rhino-

AI agents use set_object_layer to create or update resources in GOLEM-3DMCP-Rhino- — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GOLEM-3DMCP-Rhino- environment.

Medium Risk

Why set_object_layer needs a policy

Moving objects between layers in a CAD application is a reversible metadata/organizational change. The tool modifies object state but does not destroy data (not Destructive), does not execute code (not Execute), and does not involve financial operations (not Financial). This is a typical Write operation that creates or modifies data reversibly.

From the tool's definition Tool name is 'set_object_layer' and description states it will 'Move one or more objects to a different layer.' This modifies object properties (layer assignment) in a reversible manner without deleting data or executing arbitrary code.

How to control set_object_layer

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 set_object_layer:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_object_layer": {
      "limits": [
        {
          "counter": "set_object_layer_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

set_object_layer 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.

  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.

Questions about set_object_layer

What does the set_object_layer tool do? +

Move one or more objects to a different layer. It is categorised as a Write tool in the GOLEM-3DMCP-Rhino- MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_object_layer? +

Register the GOLEM-3DMCP-Rhino- MCP server in PolicyLayer and add a rule for set_object_layer: 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 GOLEM-3DMCP-Rhino-. Nothing to install.

What risk level is set_object_layer? +

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

Can I rate-limit set_object_layer? +

Yes. Add a rate_limit block to the set_object_layer 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 set_object_layer completely? +

Set action: deny in the PolicyLayer policy for set_object_layer. 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 set_object_layer? +

set_object_layer is provided by the GOLEM-3DMCP-Rhino- MCP server (thekinghippopotamus/golem-3dmcp-rhino-). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every GOLEM-3DMCP-Rhino- tool call.

Start from GOLEM-3DMCP-Rhino-, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
