ChatSocket

Not a developer? Check out ChatSocket UI — a ready-to-use desktop app built on top of this mod that gives you chat overlays, text-to-speech narration, an AI auto-reply bot, and more. No coding required.

ChatSocket is a Fabric mod that runs a lightweight WebSocket server directly inside your Minecraft client. It bridges your in-game chat with any external application that can speak WebSocket — no plugins, no server-side setup required.

How it works

When you load into a world or server, ChatSocket opens a local WebSocket endpoint (default: ws://127.0.0.1:8080/). From that point on:

• Incoming chat is captured and forwarded to all connected clients as a JSON message:

  { "type": "chat", "message": "ꜱᴄᴏᴜᴛ Br_IceyVr9 » hey everyone" }

• System messages (server announcements, join/leave notices, etc.) are forwarded the same way with "type": "system".
• Outgoing messages sent by a connected client are injected directly into your chat, as if you typed them yourself.

Use cases

• Chat overlays — display Minecraft chat in a custom UI on a second monitor
• Bots and auto-responders — react to messages with scripted or AI-generated replies
• Text-to-speech — narrate incoming chat through a local TTS engine
• Logging and analytics — pipe chat history into any tool that can open a WebSocket

Requirements

• Minecraft with the Fabric mod loader
• Any WebSocket-capable client (browser, desktop app, script, etc.)
