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

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

## Why set_active_view is rated High

This tool changes the active viewport in Rhino, which is an external application state change. While not destructive or data-modifying in a traditional sense, it triggers an operation in an external tool (Rhino), classifying it as Execute. The blast radius is low since it only affects which viewport is currently active and does not modify geometry or data.

From the tool's own definition: "'Set the active Rhino viewport by name' — triggers an external operation within Rhino that changes application state"

## Use case

AI agents invoke set_active_view to trigger actions in Aos. 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 Aos:

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