AMCDB (Another Minecraft-Discord Bridge)

AMCDB is a Fabric/Quilt mod to connect your Minecraft server to a Discord server. You can connect in-game chat to a Discord channel, set up a channel for the server console, and even run server commands from anywhere!

Here's what it looks like in Minecraft...

...and here's what it looks like in Discord!

In case you prefer to see in-game messages in Discord appear to come from players (and see their player heads as avatars!), AMCDB supports Discord webhooks as well:

Key Features

• AMCDB is fast and lag-friendly. It does almost all its work off the main server thread, so there's no impact to game performance.
• AMCDB is flexible. You can configure everything just the way you want it -- customize how messages look in game and in Discord, put the most useful information for you in the channel topics, even give the Discord bot a clever status message!
• AMCDB is stable and compatible. It doesn't use mixins to modify Minecraft code, so it rarely breaks between Minecraft versions and it works well with just about any other Fabric mod.
• And lastly, AMCDB is fun. It supports all sorts of cool Discord features, like:
  • font styles...
    
  • ...name colors...
    
  • ...and even spoiler text you can hover to reveal!
    

Installation

Follow these steps to set up AMCDB on your server.

Note: you'll need to be an admin of the Discord server you want to connect.

Install AMCDB on your Minecraft server

You need a Fabric or Quilt server. Once you have that set up, make sure Fabric API is in your mods folder - that's the one dependency AMCDB has.

Then, grab the latest AMCDB .jar file from GitHub Releases or Modrinth. It'll be something like amcdb-1.1.6.jar. Put that in your mods folder.

Next, start up your server. It will crash -- that's just because you haven't configured AMCDB yet. Now that you've started the server once, there should be a file called amcdb.properties inside your config folder. Open that file in your text editor and keep it around for the next step.

Set up a Discord bot

If you've used a different Minecraft-Discord mod before, you might already have a bot. You can reuse it as long as it has the right permissions on your server - just put the token in the amcdb.properties file.

If you don't have a Discord bot:

1. Log into https://discordapp.com/developers/applications/.
2. Click New Application in the top right.
3. Give your bot a name, and click Create.
   
4. On the left side of the screen, click Bot.
   
5. Now you'll generate the token that AMCDB will use to connect. On the main part of the page, find the "Build-A-Bot" section and click Reset Token. Once you confirm and enter your 2FA code, a random string of characters will appear like the picture below -- that's your token! Click Copy.
   
6. In the amcdb.properties file you opened earlier, find the line that starts with amcdb.discord.bot.token= and paste your bot token on the end of that line. It'll look like this:

   amcdb.discord.bot.token=MTA2OTdyNTM0NzUxMyQ0MjMyNA.GYMgJ0.cvrf8Ah0jFQ8MtGQHsgDh2MrT_Iq8-56EUbm0c
   

7. Scroll down to the Privileged Gateway Intents section and turn on Message Content Intent. This is what lets your bot read messages in your Discord server so it can put them in your Minecraft game chat.
   
8. Now on the left side of the screen, move on to URL Generator under OAuth2.
   
9. Under Scopes, checkmark the bot option. Another box labeled Bot Permissions will appear. Here, choose Manage Channels, Read Message/View Channels, and Send Messages, then click Copy.
   
10. Paste the URL you copied into a new browser tab, select a server, click Continue, then Authorize. You should see the bot join your Discord server!

Configure the chat channel

AMCDB has a lot of settings you can configure, but besides the bot token, there's only one you need to get started -- you need to tell AMCDB the ID of the channel you want to use for the in game chat. You'll probably want to create a new text channel for this, since all the messages in that channel will appear in Minecraft and vice versa.

To get the channel ID, enable Developer Mode in your Discord app. Open the settings menu, then Advanced on the left. Then, turn on Developer Mode.

Once Developer mode is turned on, you can right click on the channel you want to use and click Copy ID. Paste that ID into amcdb.properties right next to amcdb.discord.chat.channel=. It'll look like this:

amcdb.discord.chat.channel=1046313040837832782

If you want to set up a channel for the server console, copy its ID too and paste it next to amcdb.discord.console.channel=. The console channel supports running commands that you send via Discord; this feature is disabled by default for safety, but you can enable it by changing the setting amcdb.discord.channels.console.enableExecution= to true.

Then save the amcdb.properties file and start your Minecraft server again. If you've done everything correctly, anything you type in the game chat should appear in the Discord channel, and anything you type in the Discord channel should appear in your game!

Feel free to explore the rest of the amcdb.properties file, as that's where all of the configuration settings for AMCDB live. If you change anything, you'll need to stop and start your Minecraft server for the new settings to take effect.

Configure webhook mode

If you want to display Minecraft player heads as Discord avatars, you'll need to enable webhook mode. This is optional -- AMCDB will work fine if you don't set up a webhook.

To set up a webhook, follow these steps:

1. Open your Discord server Settings page.
2. On the left, select Integrations (under the "Apps" category).
3. Click on "Webhooks", then "New Webhook".
4. Click on your new webhook, change its name to Minecraft (or whatever you like), and set the channel to the channel you want to use for Minecraft chat.
5. Click "Copy Webhook URL".
6. Paste the URL into amcdb.properties next to amcdb.discord.channels.chat.webhookUrl=. Don't forget to uncomment that line by removing the # at the beginning.
7. As always, save the amcdb.properties file and restart your server. You should start to see in-game messages appearing in Discord with player names and avatars!

Upgrade

Generally, you can upgrade AMCDB simply by replacing the .jar file with the new version.

When you upgrade, it's a good idea to check whether new properties have been added to amcdb.properties; you can find latest version of the default configuration here. Occasionally, new required properties are added; this will cause your server to fail to start after updating the .jar until you add the new properties to your configuration.

You can also update your properties file by forcing AMCDB to generate a new one:

1. Stop your Minecraft server
2. Rename amcdb.properties to a temporary name, e.g. amcdb.properties.old
3. Update the .jar file and start your server. AMCDB will generate a new amcdb.properties template, and the server will stop just like with a new installation.
4. Copy your settings from amcdb.properties.old to the new amcdb.properties.
   • You can also simply copy any missing properties into amcdb.properties.old and then rename it back to amcdb.properties.
5. Start your Minecraft server.
