Mosfet Minecraft Bot

A general-purpose Minecraft 1.16 bot written in Python that uses an actual Minecraft account to play.

Mosfet is able to farm wood by cutting trees, farm crops, gather sand, farm netherwart, and trade with villagers to get emeralds. He can eat, sleep, and flee from threats.


  • Python >= 3.6
  • pip, virtualenv, git, wget, unzip

Linux Setup

Assuming Debian / Ubuntu based distro:

$ sudo apt update
$ sudo apt install build-essential python3 python3-dev python3-pip virtualenv git wget unzip

$ git clone
$ cd minecraft-bot/


If you want to use the built-in burner account (Minecraft name mattstack):

$ ./

Or, use PORT to specify a custom port to connect to:

$ SERVER=localhost PORT=12345 ./

Or, if you have your own alt account for the bot:

$ PASSWORD=supersecret ./


How to Cache Items

How to Grab Supplies


The command prefix character is the last character of the bot's name. For example, if the bot's name is mattstack, then you would issue commands like kfarm wood or kpos. This lets you run multiple bots on the same server.

In the following examples, we'll assume the bot's name is mosfet1, so commands would be ran like 1farm wood or 1pos.

The exception are the below public commands, they can optionally be prefixed with ! and all bots will run the command.

Commands can be issued in public chat or private message like /msg mosfet1 1farm wood. The bot will reply the same way the command was issued.

Use echo to make Mosfet run Minecraft commands. For example, 1echo /sethome home will cause him to issue the /sethome command.
