## Facts

- Tool: `createAction`
- Server: Spline MCP Server (`aydinfer/spline-mcp-server`) — https://policylayer.com/tools/aydinfer-spline-mcp-server.md
- Homepage: https://github.com/aydinfer/spline-mcp-server
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why createAction is rated Medium

The tool appears to create a new action object within the Spline 3D design context (likely for animations or interactions), which is a reversible write operation. The empty description lowers confidence slightly, but the consistent pattern of 'add' and 'create' verbs across sibling tools and the server's stated capability to 'create animations through natural language commands' strongly suggests this creates design…

From the tool's own definition: "Tool name 'createAction' combined with server context showing operations like 'addCamera', 'addDirectionalLight', 'addHanaInteraction', 'addHanaState', and 'addMaterialLayer' — all write operations that create or modify 3D design elements."

## Use case

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

## 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": {
    "createAction": {
      "limits": [
        {
          "counter": "createaction_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
