How to Connect Minecraft Chat to Discord with DiscordSRV

Install DiscordSRV

On Mods → Plugins, search for DiscordSRV, add it, and click Apply to server. Wait for Online. The plugin creates its config on the first start.

Create the Discord bot

1. Go to discord.com/developers/applications and create an application.
2. Under Bot, copy the bot token. Keep it private.
3. Turn on Server Members Intent and Message Content Intent.
4. Invite the bot to your Discord server with the bot scope.
5. Turn on Developer Mode in Discord, right-click your chat channel and copy its ID.

Fill in the config

1. In the panel, open Files → plugins/DiscordSRV/config.yml.
2. Put the token in BotToken.
3. Put the channel ID in Channels, as the value for global.
4. Save the file and restart the world.

Chat stops when the world sleeps

An empty world sleeps to save resources, and the bot goes offline with it. It comes back when someone joins.
