ArcadiaBridge

ArcadiaBridge

A Discord ↔ Minecraft bridge for one or many servers: two-way chat, account verification, synced sanctions, player reports with Discord buttons, cross-server chat, staff chat and topic channels.

Server-side mod for NeoForge 1.21.1, built for the Arcadia: Echoes of Power network and fully open source. One shared MySQL/MariaDB database lets all your servers work as one: a link, a ban or a mute applies everywhere.

Features

Discord ↔ Minecraft

• Two-way chat between a Discord channel and the Minecraft chat, with the player's LuckPerms prefix. Each server can have its own channel.
• Announcements: server start and stop, joins, leaves, deaths.
• Two display styles: compact (one line per event, all sent by the bot) or rich (player messages through a webhook with their head, announcements as coloured embeds).
• /online on Discord: who is connected, on which server.
• Mentions are neutralised both ways: nobody can ping @everyone from Minecraft.

Account verification

• On first join, the player gets a private code and enters it on Discord with /verify. Codes are random, hashed, single-use and expire.
• Optional grace period or kick mode, chat blocked until verified, a Discord role for verified players.

Moderation

• Ban, temporary ban, mute, temporary mute, warnings, with full history, from the game or from Discord (/mc).
• Synced both ways: a ban in game bans the linked Discord account, a Discord ban bans the linked Minecraft account, a mute becomes a Discord timeout. Durations really expire.
• Reports: /report <player> <reason> in game, sent to the staff on Discord with Ban / Mute / Ignore buttons.
• Ban evasion alerts: the staff is warned when a banned account shares the address of a joining player (alert only, never an automatic sanction; addresses are never stored, only a salted fingerprint).

Several servers, one community

• Cross-server chat: players of all your servers talk together; each one can stay local with /chat local. On Discord, each server keeps its own channel.
• Staff chat shared by all servers (/sc), which also receives reports and alerts.
• Topic channels (#trade, #recruitment…) created by the staff and joined by players with /canal.
• Private messages across servers: /msg reaches a player connected to another server.
• Automatic primary server: Discord commands and expirations are handled by one server at a time, elected through the database; if it stops or crashes, another one takes over within seconds.

Tabbed chat (optional)

With the client mod ArcadiaChat, players get chat tabs (global, server, private, staff, channels), @mentions, a typing indicator and one-click server switching. Players without it keep the normal chat.

Installation

1. Drop the jar in the server's mods folder (server side only, players do not need it).
2. Create a MySQL or MariaDB database, shared by all your servers.
3. Create a Discord application and bot, enable the Message Content intent, and invite it with these permissions: View Channels, Send Messages, Embed Links, Manage Messages, Ban Members, Moderate Members, Manage Roles (and Manage Webhooks for the rich style).
4. Start the server once, then fill config/arcadiabridge.toml: database, bot token, server and channel IDs, and a unique serverId per server.

The default language is French: set language = "en_us" in the [general] section for English. All messages can be edited in config/arcadiabridge/lang/.

Commands

Discord: /verify, /online, and /mc (ban, tempban, unban, mute, unmute, warn, info, unlink) for members with the Ban Members permission or a configured staff role.

Permissions go through the NeoForge permission API, so through LuckPerms if installed; without it, staff commands are for operators.

Compatibility

• Minecraft 1.21.1, NeoForge, Java 21, server side only.
• Optional: LuckPerms (permissions and chat prefixes), LPC (chat formatting is kept across servers), No Chat Reports.
• Bundles JDA, HikariCP, MySQL Connector/J and their dependencies (relocated, no conflict with other mods).
