McChatBridge
Simple communication for players (and others) on the server via a web interface, with a variety of different features that I found useful.
⬇ Download on Modrinth
This is a simple mod for Minecraft 1.21.1 NeoForge. I just had an idea and decided to implement it with the help of AI (Antigravity Gemini 3.5 Flash), and Claude Opus 4.8 (I didn't like Gemini). I am unlikely to update this mod further, as I made it just for myself and my friends. However, I will leave the source code available (hopefully, I can figure out how to do that). This is a server-side mod. To see images sent to the game chat via McChatBridge, install the ChatImage mod by kituin on your game client.
Do whatever you want with this project.
McChatBridge launches a built-in HTTP web server directly within the Minecraft server. Through a browser, players (and others) can:
Read and write to the global chat: Messages are synchronized in both directions—from web to game and from game to web.
Send Private Messages (PMs): Direct messages to specific players on the server; PM history is encrypted using AES-256-GCM.
Upload and send images: Pictures are displayed in the web chat, while a clickable link appears in the game.
Play a "Clicker" mini-game: Mine ore through clicks, receive resources in your inventory, and transfer them to players on the server.
View online players in real-time: See who is online along with their avatars. Receive system notifications: Get alerts for player logins/logouts and deaths.
All settings are handled via configuration files. They are located in your server's config folder. You can change the port, disable the mini-game, or disable image uploads by users.
How can users and you access the web interface?
