Minecraft Discord Bot

A Discord bot designed to interact with a Minecraft server, providing RCON commands, automated restarts, backups, and more.
The bot is meant to be deployed to the same machine as a Minecraft server,
and by providing the MC server path in the bot's config, let it manage the MC server through discord slash commands. One bot instance manages one MC server.

Features

Manage the Minecraft server from Discord

• Execute RCON commands with authorization (Discord roles or user whitelist)
• Chat with in-game players from Discord
• Bar chart with player count over time
• Provide a modpack download link and setup instructions for new players
• Automate server restarts and backups easily and quickly
• Preview and retrieve server log files and statistics about lag, resource use and more
• MC Bot rolling logfile at _logs/mc_bot.log which also includes command calling history
• Warnings about server not keeping up, or external chunks causing lag

Backup

The bot can do frequent backups of the Minecraft world, and then delete most of them after a configured amount of time. For example backup every 15min and delete most of those, the frequent backups after 24 hours, keeping one per day. These can also eventually be deleted after for example 6 months.
Backups can then be restored easily with the /backup restore command. If the desired backup is too old to fit in the dropdown, a optional timestamp can be added to look at backups before that timestamp, ex: /backup restore 15-01-2025

Chat

Discord users can spawn a chat window, and see the player's chat messages from the game. They can then talk to the players using say to warn about a restart, ask about a problem or just say hi.

Players Graph

Show who is online, who has joined today, and how many joined yesterday. Gives you an overview of how active the server is at a glance.

Admin Permissions

The admin_users and admin_roles fields in the configuration file define who has access to restricted 🔒 bot commands.

admin_users: # List of Discord user IDs with admin permissions
    - 123123123123123123  # Ola Nordmann
    - 123123123123123124  # John Doe
admin_roles:  # List of Discord role IDs with admin permissions
    - 123456789045678907 # "Minecraft Admin" role

The admin_users list contains specific Discord user IDs, granting admin privileges to those users individually. The admin_roles list contains Discord role IDs, allowing all members with those roles to use admin commands. To find a user or role ID, enable Discord's Developer Mode, then right-click the user or role and select Copy ID.

Logfile

A logfile for the bot is created at _logs/mc_bot.log. There is also a debug.log file with DEBUG log level for trouble shooting. These are rolled over at midnight and are reused across bot restarts.
