What io.github.kastelldev/kastell does

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.

Why Kastell?

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.

Quick Start

# Interactive mode -- no commands to memorize
npx kastell

Running kastell without any arguments launches an interactive search menu with a gradient ASCII banner and quick-start examples. Browse actions by emoji-categorized groups, type to filter results instantly, and configure options step by step -- no need to remember any command names or flags.

  $ kastell init --template production  → deploy a new server
  $ kastell status --all                → check all servers
  $ kastell secure setup                → harden SSH + fail2ban
  $ kastell maintain --all              → full maintenance cycle

? What would you like to do?
   Server Management
❯    Deploy a new server
     Add an existing server
     List all servers
     ...
   Security
     Harden SSH & fail2ban
     Manage firewall (UFW)
     ...

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 configura
