Server security is fragmented. Lynis scans but doesn't fix. OpenSCAP is powerful but complex. Custom scripts work until they don't -- and nobody maintains them. Each tool has its own output format, its own update cycle, its own learning curve.
Kastell takes a different approach: one CLI that audits, fixes, hardens, and monitors. Scan your server, apply safe fixes, lock it down to production standards, and keep watching -- all with the same tool.
AI-native from day one. Kastell ships with a built-in MCP server, so Claude, Cursor, or any MCP-compatible AI agent can manage your servers directly. Go from a prompt to production hardening in seconds.
You don't need four separate tools to secure a server.

Each action includes sub-options (server mode, template, log source, port number, etc.) and a <- Back option to return to the main menu at any point.
If you already know the commands, you can still use them directly:
kastell init # Deploy a new server
kastell status my-server # Check server status
kastell backup --all # Backup all servers
Kastell handles server provisioning, SSH key setup, firewall configur
