Claude turns a terminal Minecraft clone into multiplayer with one prompt
The author says they used Claude Opus 5 to add multiplayer support to a terminal-based Minecraft TUI in a single prompt. The demo:
- renders directly inside the terminal
- is built entirely in Rust
- can be installed with cargo install termcraft-3d
- runs with a seed parameter like termcraft-3d --seed N
The post is a follow-up to a quoted demo where Claude reportedly built the original TUI Minecraft version with Warp’s harness in about an hour. This one pushes it further by making the experience multiplayer, which makes it both a coding-agent demo and a fun AI-made mini-game showcase.
