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

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

## Why backup_config is rated Medium

This tool creates/writes a backup file but does not destructively modify or delete existing data. While backups are generally defensive, the creation of a backup file in a firewall system could be misused to exfiltrate sensitive configuration data (passwords, VPN keys, firewall rules) if the backup is then retrieved.

From the tool's own definition: "Tool name 'backup_config' and description 'Create a backup of the OPNsense configuration' indicate creation of a new backup artifact."

## Use case

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