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

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

## Why add_node is rated Medium

Adding a node to a scene is a reversible write operation that modifies project state. It creates new structural elements but can be undone (nodes can be removed). This is less severe than Destructive (which would be irreversible deletion) but more impactful than Read operations.

From the tool's own definition: "Tool description states 'Add a node to an existing scene' — directly creates/modifies scene structure in a Godot project. The sibling tools confirm this is a development environment (create_scene, edit_node, export_mesh_library, launch_editor)."

## Use case

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

## Recommended policy (PolicyLayer)

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

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