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

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

## Why set_app_status is rated Medium

This is a Write operation because it creates or modifies data reversibly. Activating or deactivating an app changes its configuration state without permanently deleting data. While it could impact service availability, the effect is reversible by re-activating the app.

From the tool's own definition: "Tool description states 'Activate or deactivate a registered app' — this modifies application state by changing its operational status. The action is reversible (can toggle between active/inactive states)."

## Use case

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

## Recommended policy (PolicyLayer)
