Chat Filter
by CodeNex
Chat Filter removes automated server messages that start with set prefixes, such as the Broadcast and Crates notices, from the client's chat window.
What it does
Many servers print automated announcements into chat, and the Chat Filter mod hides the ones that begin with specific prefixes, such as messages marked Broadcast or Crates. Filtering can be switched on or off in game with the G key, so no restart or config editing is needed to change it. The mod is built for Fabric on Minecraft 1.21.5, and its files are dated 2025-07-23 for the first release and 2025-08-03 for the latest update.
Only the player's client runs Chat Filter, so it works on any server without the server owner installing anything or granting permissions. Its code is under the GNU General Public License v3.0 or later, and the source code and issue tracker are public. The mod is described as lightweight and is meant to stay out of the way of other chat and gameplay mods.
Key features
Prefix-based filtering
Messages that start with chosen prefixes are removed automatically, so repeated server notices stop crowding the chat.
Toggle with the G key
Pressing G in game turns filtering on or off, which lets a player check announcements when they want them.
No restart needed
Filtering can be changed while the game is running, without reconfiguring and restarting the client.
Light and non-intrusive
The mod leaves other features and performance alone, and it works alongside other chat mods.

Use cases
Busy multiplayer servers
On servers that send frequent automated broadcasts, the filter keeps the chat readable for conversation between players.
Focused play
Players who want their chat to show only player messages can hide server noise during building or exploration.
Who it’s for: Players who join servers that post automated announcements in chat and want those notices hidden on their own side. The mod is for Minecraft 1.21.5 with Fabric only.
How it compares
Chat Focus is a Fabric client mod under the MIT License that covers 1.21 – 1.21.11 and is not open source. Cavern Chat is also a Fabric client mod under the MIT License covering 1.21 – 1.21.11, and it is open source. MuteIt is a Fabric client mod under the Apache License 2.0 for 1.21.6 – 1.21.8 and is not open source, so its version range is narrower than Chat Filter's single 1.21.5 target.
