AFK Chat Alert
by MOHD_GS
AFK Chat Alert plays a sound when someone in global chat mentions a player's name or a custom keyword while that player is away from the keyboard.
What it does
AFK Chat Alert is a client-side Fabric mod that watches incoming chat messages. When the player has been idle longer than a configured timeout, a message that contains the player's exact in-game name or one of the user's custom keywords triggers an audio alert. Players can add phrases, slang or other player names to the keyword list, and the alert uses a pre-loaded vanilla sound such as a note block or level-up cue.
The mod needs Cloth Config API and Fabric API to run, and Mod Menu is optional for opening its settings screen. Only the client needs the mod, so servers can run without it. Files are released for Fabric 1.21.11 only, with the latest build 1.3.3 dated 2026-05-24. The code is open source under the MIT License.
Key features
Username mention alert
The player's exact in-game name is watched automatically, so no keyword setup is needed to hear when someone addresses them.
Custom keyword triggers
A keyword list in the settings menu accepts phrases, slang and other player names, and each entry can be added, edited or reset.
Idle-based detection
The alert only fires after the configured AFK timeout passes, so messages sent while the player is active stay silent.
Cooldown sliders
A cooldown setting limits how often the sound plays, which keeps fast-moving global chats from producing constant alerts.
Sound settings panel
An alert sound dropdown offers a set of pre-loaded vanilla sounds, with a separate panel for choosing the cue.

Use cases
Multitasking away from the game
A player who browses the web, watches a video or takes a break can leave the game running and still hear when another player calls them.
Who it’s for: Players who leave Minecraft running in the background while doing other things, and players who want an audio cue for their name or a few keywords in global chat.
How it compares
PingMention runs on Fabric for 1.21.11 only and is client-side only under the MIT License, with no open source claim stated. ChatReply is also client-side only and MIT licensed, covering 1.21 – 1.21.11 on Fabric. Mention is server-side only, uses CC0 1.0 Universal, and targets 1.21.11, so it changes what the server does rather than what the player hears.
