Description

Cross Server Chat:

Cross Server Chat is a simple yet powerful serverside networking tool that links chat, TAB, and operator commands across multiple Minecraft worlds through one Discord channel. The mod is server-only, so players do not need to install anything. Each world keeps its own identity with a [ServerName] tag, while Discord acts as the shared mailbox. No proxy, Redis, or Velocity setup is required.

Cross-Server Chat:

Share player chat across every linked world in the format [Camelot] Poe: hello
Optional Discord webhook so messages use the player's name and skin
Optional Discord-to-Minecraft chat as [Discord] name: message
Optional join and leave broadcasts on every linked world
Works beside Discord Integration when you use a different bot and a different channel
Loop-safe identity so a world never echoes its own messages back to itself

Network TAB:

Custom header and footer with Minecraft color codes
Live network list with %worlds%, player counts, and TPS
Per-viewer name colors: you can be gold while other players stay white
Visual HTML editor written to config/CrossServerChat/tab-editor.html
Instant apply with /cross_server reload, no server restart

Network Commands:

/server_all <command> plus /y confirmation to run an operator command on every linked world
/cross_server reload and /csc reload to reload config.toml and tab.toml
Command packets are removed from Discord after other worlds have read them

Setup Guide:

1. Create a Discord bot:

Open the Discord Developer Portal and create a new application
Open Bot, create the bot, and copy the token
Enable Message Content Intent
Invite the bot with View Channel, Send Messages, Read Message History, and Manage Messages
Do not reuse the Discord Integration bot

2. Create a dedicated Discord channel:

Make a channel only this mod will use
Do not reuse the Discord Integration chat channel
Enable Discord Developer Mode, right-click the channel, and copy the Channel ID
Optional: create a webhook in that channel if you want player names and skins in Discord. The same webhook URL can be used on every world

3. Edit config/CrossServerChat/config.toml on every world:

serverName must be unique per world, for example Camelot, Tristram, Test
botToken, channelId, and webhookUrl must be the same on every world
allowDiscordChat = true if people should be able to talk from Discord into Minecraft
broadcastJoin and broadcastLeave default to false
hideCommandMessages = true keeps /server_all packets from sitting in the Discord channel
Run /cross_server reload or restart after saving you custom player list tab

4. Edit TAB:

Open config/CrossServerChat/tab-editor.html in a browser
Design the header, footer, world list, your TAB name color, and other players' TAB name color
Copy or save the TOML into config/CrossServerChat/tab.toml
Run /cross_server reload
