AutoDisconnect-check
by newbiewood
AutoDisconnect-check is a Fabric utility that disconnects the player from a server when a configured trigger appears, such as a keyword in chat or a boss bar.
What it does
The mod watches for specific in-game events and disconnects the client from the current server when one of them is detected. Triggers cover incoming chat messages that contain custom keywords, large titles shown in the center of the screen, and boss bars, including the Ender Dragon bar and bars added by custom server bosses. The goal is to leave a situation before it can cause harm, such as a server-wide event the player wants to avoid.
Cloth Config API is required, and Mod Menu is optional; with Mod Menu installed, the configuration screen can be reached from its list of mods. Trigger behavior is set there, and a built-in cooldown stops repeated disconnections in quick succession. The mod works with both English and Simplified Chinese text.
The mod is client-side only, so a server does not need it and players join without installing anything on the server side. It is released under the MIT License and is open source, with its source code published. Files exist for 1.21.1 only, with version 1.0.0 as the latest Fabric build, dated 2026-04-22.

How it compares
Dark Window Title Bar is a Fabric client-side mod for 1.21 under the BSD 2-Clause License and is open source, but it changes the window title bar rather than disconnecting from servers. AutoDisconnector is a Fabric client-side mod for 1.21.7 – 1.21.9 under All rights reserved and is not open source, so it does not cover the 1.21.1 build. Disconnect Trigger is a Fabric client-side mod for 1.20 – 1.21.8 under All rights reserved and is not open source, a broader version range than this mod's single target.
