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

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

## Why manage_scene is rated Medium

The capture action saves/creates scene data (Write), and activate modifies the live state of items in the home (Write). While these are reversible (scenes can be overwritten or different scenes activated), they directly alter the operational state of controlled devices. The high severity reflects that misuse could change HVAC settings, locks, lighting, or other critical home systems.

From the tool's own definition: "Tool performs 'capture (save current item states)' and 'activate (restore a saved scene)' — both are state modification operations that persist changes to the home automation system."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json

  "version": "1",
  "default": "deny",
  "tools": {
    "manage_scene": {
      "limits": [
        {
