Auton8 (Prototype) Minecraft Automation with N8N and MQTT Status: Archived / Unmaintained This project is a proof-of-concept for automating Minecraft gameplay using n8n (no/low-code workflows) over MQTT (Mosquitto) to a Fabric client mod that drives Baritone. It is not production-ready. The goal is to inspire someone to rebuild this idea properly, with better UX, safer defaults, and a broader ecosystem.

Download & install:
https://docs.docker.com/desktop/setup/install/windows-install/

Put these four files into your Minecraft mods folder:

⚠️ This prototype targets Minecraft 1.21.8 specifically. Stick to matching Fabric/Mod versions.

Downloads:

• Baritone API (Fabric 1.15.0):
  https://github.com/cabaletta/baritone/releases/download/v1.15.0/baritone-api-fabric-1.15.0.jar
• Baritone Standalone (Fabric 1.15.0):
  https://github.com/cabaletta/baritone/releases/download/v1.15.0/baritone-standalone-fabric-1.15.0.jar
• Fabric API (for 1.21.8):

• Mod Menu (for 1.21.8):

Also place the Auton8 mod JAR (from this repo’s Releases) into the same mods folder.

From the project root, double-click:

• start-docker.bat

This will run Docker Compose and bring up:

• Mosquitto on 127.0.0.1:1883
• n8n on http://localhost:5678

On the first run, the stack auto-creates:

• an empty mosquitto/config/passwd
• mosquitto/data/mosquitto.db (persistence)

Visit:
http://localhost:5678
Create your n8n account and log in.

Start your Fabric profile (1.21.8).
Open Mod Menu you should see Auton8 listed.
The mod connects to MQTT and publishes/receives on the topics below.

The current build has the following values hard-coded:
You’ll need to use these when setting up your MQTT Trigger node in n8n.
