About this Mod
VibeCraft
Vibe code without ever leaving your favourite game.
Write code, review PRs, and ship features — all from your favourite in-game location.
Why alt-tab to a terminal when you can code from a mountaintop in Minecraft?
VibeCraft puts Claude Code directly inside your game. Point it at any project on your PC, give it permissions, and let it work — while you mine, build, or just vibe.
What can it do?
- Chat with Claude AI without leaving the game
- Point Claude at any folder on your PC and have it read, write, and edit files
- Run multi-step coding tasks — Claude chains tool calls automatically
- Full Claude Code CLI toolset: file read/write, bash, search, and more
- Optional direct Anthropic API route with in-game terminal command approval
