chatblocker_
Minecraft multiplayer chat can be a chaotic place. Between server announcements, plugin spam, and the occasional player who just will not stop repeating the same word, your chat log can become a wall of noise. chatblocker_ is a lightweight, client-side Fabric mod built for Minecraft 1.21.8 that lets you filter all of that out without anyone else ever knowing. You set the keywords, and the mod quietly hides matching messages from your view only.
This is not a server-side plugin, and it does not mute players. It simply makes certain messages invisible to you. Other players still see their own messages, the server still processes everything normally, and your chat becomes exactly what you want it to be. It is pure, local convenience.
Why Use chatblocker_ for Minecraft
The biggest advantage of chatblocker_ for Minecraft is its surgical precision. You are not muting a player entirely, and you are not losing context. You are only removing the messages that contain the specific keywords you have configured. If someone says something you do not want to see, that single line disappears from your screen. Everything else from that player remains visible.
This makes it perfect for a variety of situations:
- Blocking spammy words or phrases in public servers
- Hiding repeated advertisements or bot messages
- Filtering out spoilers for games, shows, or events
- Removing profanity or toxic language without losing the conversation
- Cleaning up server-wide announcements that you find irrelevant
Because the mod works on your client only, there is zero impact on server performance or on other players' experiences. It is a personal tool for a personal chat experience.
Key Features of chatblocker_
The mod comes packed with practical features that make it a cut above simple chat filters. Here is what you can expect after you download chatblocker_:
Client-Side Filtering
All filtering happens locally. Messages containing your keywords are hidden on your screen only. Other players are completely unaware that you are filtering anything, and the server sees no change in traffic.
Smart Exemption for Your Own Messages
When you send a message, it normally appears in your chat as an echo. If that message contains one of your blocked keywords, the mod would normally hide it. chatblocker_ solves this with an "exempt own echo" feature that keeps your own messages visible. On offline-mode servers, this works via text matching, and you can disable it in the config if you prefer.
System Message Filtering
Beyond player chat, the mod can also filter system messages. Server announcements, plugin broadcasts, and other automated messages that hit your keyword list will be hidden as well. This gives you full control over every line that appears in your chat window.
Flexible Matching
Keywords are matched as substrings and are case-insensitive. This means a keyword like "badword" will match "BADWORD", "BadWord", and "thisisabadword". Both English and Chinese keywords are fully supported, making the mod useful for players across different language communities.
In-Game Management
You do not need to restart the game to add or remove keywords. The mod provides simple in-game commands that take effect immediately:
/chatblocker add <keyword>– Adds a keyword to the block list/chatblocker remove <keyword>– Removes a keyword from the list/chatblocker list– Shows all currently blocked keywords/chatblocker reload– Reloads keywords from the config file
Graphical Configuration
If you prefer a visual interface, the mod integrates with ModMenu. From the main menu, you can navigate to Mods, find chatblocker_, and click the Config button to open a full graphical settings screen powered by YACL. This makes managing your keyword list and toggling options even easier.
How to Install chatblocker_
Installing the mod is straightforward. The process for how to install chatblocker_ follows the standard Fabric mod setup for Minecraft 1.21.8.
Requirements
Before you begin, make sure you have the necessary dependencies installed:
- Fabric Loader for Minecraft 1.21.8
- Fabric API (required)
- YetAnotherConfigLib (required)
- ModMenu (optional, but recommended for the GUI config)
Once those are in place, simply place the chatblocker_ jar file into your .minecraft/mods folder and launch the game. The mod will load automatically, and you can start adding keywords right away using the commands listed above.
For players who prefer a more streamlined setup, the foxygame.net launcher offers a one-click install for chatblocker_ that handles version compatibility and dependency checks automatically, so you can jump straight into the game without manually juggling jar files.
Configuration File
All settings are stored in a JSON file located at .minecraft/config/chatblocker.json. Here is an example of what the file looks like:
{
"enabled": true,
"exemptOwnEcho": true,
"keywords": ["example1", "badword"]
}You can edit this file directly if you prefer, but the mod also handles corruption gracefully. If the file becomes damaged, chatblocker_ will automatically recover and load with default settings instead of crashing, which is a thoughtful touch for stability.
Open Source and Community Driven
chatblocker_ is open source under the MIT License. The project welcomes feedback and contributions from the community. If you have ideas for new features or find a bug, you can report it on the official GitHub repository. The foxygame.net launcher also keeps its catalog of add-ons up to date, so you can check for new versions of chatblocker_ there and enable auto-updates to always run the latest build.
