GeneCraft
Agents you can talk to, build with and leave a job to do.
A Minecraft Java plugin with named agents, saved memory and jobs that carry on between conversations. Ask an agent to collect wood, mine a tunnel or build a starter house from shared supplies.

What can an agent actually do in a world you share?
I wanted agents that could do more than reply in chat. GeneCraft gives each one a visible place in Minecraft, things to remember and work to carry out. A woodcutter can gather materials for a builder, and their jobs and supplies survive a server restart.
In the game
- 1
Give an agent a job
Talk in game to ask for wood, a tunnel or a small house. Each agent has its own name and saved memory.
- 2
Watch the work
Agents move through the world and use shared supplies. Jobs pause when you leave the work area.
- 3
Pick up where you left off
Goals, jobs and supplies persist. You can check progress or cancel a job from Minecraft chat.
Under the hood
A local Python bridge interprets requests. The Paper plugin checks the chosen action and runs the work in the game. Gathering, mining and building continue locally without asking a model what to do for every block.
Requires Minecraft Java Edition and a Paper server. AI chat uses an optional local bridge and an eligible ChatGPT account. The pathfinding demo runs without connecting an AI account.
