## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "copy_object",
    "arguments": {}
  }
}
```

## Why copy_object is rated Medium

Copying an object in FreeCAD creates new data (a duplicate) reversibly; the operation can be undone and does not permanently destroy information. This qualifies as Write rather than Read (which merely retrieves) or Destructive (which irreversibly deletes). Severity is medium because misuse could clutter the model or consume resources, but effects are non-destructive and localized to the project file.

From the tool's own definition: "Tool name 'copy_object' indicates creation of a duplicate of an existing 3D model object in FreeCAD. The description is empty, which lowers confidence, but the naming convention and context of a modeling server (alongside sibling tools like add_sketch_line,…"

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches FreeCAD Robust MCP Server:

```json

  "version": "1",
  "default": "deny",
  "tools": {
    "copy_object": {
      "limits": [
        {
          "counter": "copy_object_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
