What mcwrapper is

mcwrapper is a free Minecraft server wrapper for Linux, macOS, and other POSIX-compatible systems, intended for server administrators. It can start, stop, restart, and check a server's status, as well as send commands through a named pipe (FIFO) called command_input. Its backup action pauses world-data writing while it copies and compresses data, then resumes writing. Backups receive timestamps, a latest symlink is created, and the default retention is five backups. Restoring stops the server if necessary, saves current data, replaces the world directory with the selected backup, and restarts the server if it had been running; connected clients are disconnected during restoration. The log action follows the Minecraft server log in real time. An install action downloads the current minecraft_server.jar from Mojang and places it in the configured location. Settings can come from environment variables or mcwrapper.conf files in documented locations. Installation is available through RubyGems.org with the command gem install mcwrapper. The project provides a README and wiki pages covering setup, actions, configuration, and automated backups. The MIT license states that the software is provided without warranty.

Good

  • Can start, stop, restart, and check server status
  • Backups are timestamped and create a latest symlink
  • Default backup retention is five backups
  • Log action follows the server log in real time
  • Can download the current server jar

Watch out

  • Restore disconnects connected clients
  • Restore replaces the world directory with a selected backup
  • MIT license provides the software without warranty

Who it suits

It suits Minecraft Java server administrators on Linux, macOS, or other POSIX-compatible systems who want server controls and backup actions. Administrators should account for client disconnections when restoring a backup.

Verdict

mcwrapper combines basic server control with compressed backups, restoration, and live log following. Its restore process interrupts connected clients, so that limitation matters when choosing how to manage a running server.
