M Contain Mod (26.3, 26.1.2) – Lock Up Griefers and Gate Unverified Server

M Contain Mod protects multiplayer servers with a spawn gate and a player jail system. It keeps unverified newcomers at world spawn in Adventure mode so nobody breaks or places blocks without verification. Server operators also get a handy jail tool to lock up rule-breakers for a set number of minutes and return everyone to Survival mode afterward.

Features:

• Spawn Gate: Traps unverified players inside the world spawn area like an in-game whitelist for public or private servers.
• Player Jail: Locks troublemakers inside an escape-proof cell with an optional sentence timer in minutes.
• Forces both unverified newcomers and prisoners into Adventure mode so nobody breaks or places blocks.
• Teleports trapped players right back to the set location whenever someone tries to leave the area.
• Returns players to Survival mode automatically once an operator verifies the player or the jail timer finishes.
• Lets server operators set a custom teleport radius for the spawn gate and every saved jail cell.
• Runs on the server side for Fabric multiplayer worlds.

Commands:

• /mcontain gate [radius]: turns on the gate at world spawn with a default radius of 16 blocks.
• /mcontain gate disable: turns off the spawn gate.
• /mcontain gate verify [player]: approves a player or yourself to leave the spawn area.
• /mcontain gate unverify [player]: removes verification from a player.
• /mcontain jail save <name> [radius]: saves a jail cell at your current position.
• /mcontain jail <name> <player> [minutes]: sends a player to a jail cell with an optional timer in minutes.
• /mcontain unjail <player>: releases a player from jail early.
• /mcontain jail list: lists all saved jail cells and active sentences.
• /mcontain jail clear: releases everyone and deletes all saved jail cells.
• /mcontain reload: reloads settings from config/mcontain.json.
• /mcontain status: shows the current state of the gate and jails.

How to Use:

1. Run /mcontain gate [radius] to turn on the spawn gate, or leave the radius blank to use the default 16-block area.
2. Run /mcontain gate verify [player] to let a trusted player switch to Survival mode and leave spawn.
3. Stand inside a cell and type /mcontain jail save <name> [radius] to save a jail location.
4. Type /mcontain jail <name> <player> [minutes] to send a rule-breaker to that cell.
