Duplicate a node in the scene tree

Agent View of the PolicyLayer registry record for `duplicate_node`. HTML page: https://policylayer.com/tools/keeveeg-godot-mcp/duplicate-node

## Facts

- Tool: `duplicate_node`
- Server: Godot (`@keeveeg/godot-mcp`) — https://policylayer.com/tools/keeveeg-godot-mcp.md
- Install: `npx -y @keeveeg/godot-mcp`
- Homepage: https://www.npmjs.com/package/@keeveeg/godot-mcp
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 1 (1 required)
- Recommended policy verdict: Rate-limited

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `path` | string | yes | Node path to duplicate |

Parameters from the server's own tool schema.

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "duplicate_node",
    "arguments": {
      "path": "<path>"
    }
  }
}
```

## Why duplicate_node is rated Medium

Duplicating a node creates new data (a copy) in the scene tree, which is a reversible modification. This is a Write operation—it does not execute arbitrary code, delete data irreversibly, or trigger financial transactions. The severity is medium because while duplication modifies the scene state, it can be undone (via undo/redo) and does not directly destroy data or execute external operations.

From the tool's own definition: "Tool name 'duplicate_node' with description 'Duplicate a node in the scene tree' indicates creating a new copy of an existing scene node."

Risk signals: Accepts file system path (path)

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "duplicate_node": {
      "limits": [
        {
          "counter": "duplicate_node_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
