Gamerulify

Gamerulify is a server-side modification that significantly expands the possibilities for configuring gameplay directly while the server is running. Administrators gain access to numerous game rules that can be activated or deactivated without the need to restart the server.

Among the key features of the mod is the ability to manage RCON, query, and status streams in real time. Also available are settings for maximum player count, installation of server resource packs, changing MOTD (message of the day), adjusting spawn protection size, and many other parameters.

You can control the operation of command blocks, enable or disable PvP, configure view distance, regulate creeper destructive behavior, and much more - all without stopping the server.
