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

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

## Why applySculptingBrush is rated High

Based on the name, this tool likely applies a sculpting brush operation to a 3D model within Spline, which constitutes an action that modifies geometry state. In the context of a 3D design tool, sculpting modifies mesh data. Since the description is empty, confidence is low, but the most plausible interpretation is a Write or Execute action that alters 3D object geometry.

From the tool's own definition: "Tool name 'applySculptingBrush' — description is empty and uninformative."

## Use case

AI agents invoke applySculptingBrush to trigger actions in Spline MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "applySculptingBrush": {
      "limits": [
        {
          "counter": "applysculptingbrush_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
