!mc help : shows help
!mc serverusage : shows system load in percentage
!mc serverstatus : shows if the server is online or offline
!mc whoisonline : shows who is online at the moment


$ python3 -m virtualenv .venv 
$ source .venv/bin/activate
$ pip install discord
$ pip install python-dotenv

Developing the Discord Bot

$ cat .env

from dotenv import load_dotenv
BOT_NAME = "MinecraftBot"
bot = discord.Client()
@bot.event async def on_ready():
print(f'{bot.user} has logged in.')
@bot.event async
def on_message(message):
if == bot.user:
if message.content == 'hello':
await'Hey {}')
if message.content == 'goodbye':
await'Goodbye {}')
$ python 
MinecraftBot has logged in.
  • use the command !mc to trigger our bot and subcommands for what we want
  • able to see who is playing minecraft on our server at the moment
  • able to get the status if the minecraft server is online
  • able to get the server load percentage (as the bot runs on the minecraft server)
