## Facts

- Tool: `triggerEvent`
- 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: Execute (High 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": "triggerEvent",
    "arguments": {}
  }
}
```

## Why triggerEvent is rated High

The tool appears to trigger event handlers or animations within a 3D design context. While the description is empty, the name 'triggerEvent' indicates execution of logic whose effects depend on which event is triggered. This is more severe than Write (which would be creating/modifying design elements) because it executes conditional logic/workflows.

From the tool's own definition: "Tool name 'triggerEvent' combined with sibling tools that modify scenes, add interactions, and manage state (addHanaInteraction, addHanaState) suggests execution of design logic."

## Use case

AI agents invoke triggerEvent 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": {
    "triggerEvent": {
      "limits": [
        {
          "counter": "triggerevent_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
