AutoLeaver
by A-TEAM
AutoLeaver is a Fabric client mod that disconnects a player from the server when a danger condition appears, such as a Totem of Undying being used up or health dropping to a critical level.
What it does
When the totem in the offhand is popped or removed, the client leaves the game at once, which keeps a player from dying to an unexpected attack in hardcore survival or PvP. A health threshold works the same way: once health falls to a set level, the client disconnects. The default threshold is 4 hearts, or 8 HP, and it can be changed in the settings.
An AFK mode covers the case where a player steps away from the keyboard. Once the character has stood still for a few seconds, the protection turns on, so a mob hit, a push or a broken totem makes the client disconnect. Movement turns AFK protection off again, so ordinary play does not trigger it. The features are grouped in a clean interface built with Cloth Config and Mod Menu, and the settings screen is reachable from the game's mod menu.
AutoLeaver runs on the client only, so only the player installing it needs it and the server does not. It is released under the MIT License and is not open source. Files exist for 12 release versions, 1.21 – 1.21.11, with AutoLeaver-1.0 for 1.21.11 as the latest file, published on 2026-08-01.
