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

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

## Why create_spring_arm is rated Medium

The tool creates a new scene node (SpringArm3D) and adds it to the Godot scene, which is a reversible Write operation. While not destructive, an AI agent could spam node creation or create malformed hierarchies. Severity is medium because the effect is bounded to scene structure and can be undone; there is no code execution, data deletion, or financial impact.

From the tool's own definition: "create_spring_arm creates a SpringArm3D node, which modifies the scene graph by adding a new node structure for camera control."

## Use case

AI agents use create_spring_arm 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": {
    "create_spring_arm": {
      "limits": [
        {
          "counter": "create_spring_arm_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
