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

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

## Why manage_item is rated Critical

The tool spans multiple categories including Destructive (delete, remove_tag, remove_metadata), Write (create_or_update, update_state, add_tag, set_metadata), and Execute (update_state triggers physical device changes in a smart home). Per the severity rules, Destructive is the highest applicable category.

From the tool's own definition: "actions include 'delete', 'remove_tag', 'remove_metadata' which are irreversible, alongside 'create_or_update', 'update_state', 'add_tag', 'set_metadata'"

## Use case

AI agents call manage_item to permanently remove resources in Openhab, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "manage_item"
  ]
}
```
