intruder alerts
by Berezhnyk
Intruder Alerts is a client-side Fabric mod that sends a chat message, a toast and a sound when an untrusted player enters render distance.
What it does
When a player who is not on the personal trust list comes within render distance, the client shows a chat message, a toast notification and plays a sound. Players can build the trust list with commands, mark friends and known players as trusted, and suppress alerts for them. Alerts can also be switched off entirely with a toggle command, and the mod can highlight the nearby untrusted player with a glowing effect, including when that player is invisible.
Ignore zones handle places where alerts would fire too often, such as a spawn area or a trading hub. A zone is added or removed with commands and suppresses alerts for the area it covers. The interface is translated into 13 languages. Settings are stored locally for each client, so a server owner does not need to configure anything.
The mod runs on the client only, so players install it and servers do not. Fabric is the only loader with files, and the latest build for 26.3 is 1.3.0+mc26.3, released 2026-10-09. Builds cover 1.21.1 – 26.3, and the code is licensed under the Apache License 2.0, so it is open source.
Key features
Arrival alerts
A chat message, toast and sound announce an untrusted player as soon as that player enters render distance.
Personal trust list
Players can add or remove trusted names with commands, so alerts skip friends and known players.
Ignore zones
Areas such as spawn or trading hubs can be added as zones where alerts are suppressed.
Glowing marker
An optional glowing effect is applied to the untrusted player, including while that player is invisible.
Alert toggle
A command turns all alerts on or off without changing the trust list or the zones.
