AI
Built-in MCP server
Your ISP panel now speaks AI. BillMax doesn't.
Every ISPbox workspace ships a built-in MCP server: connect Claude, ChatGPT or Cursor with one URL and let AI diagnose "why is this customer offline?", warn everyone behind a failing tower, read your LibreNMS/Zabbix alerts and run your billing reports - under each staff member's own permissions, with a full audit trail.
