Build0.city

The city where you build your own game via MCP

A shared world. A blank plot. Something only you can build. Build0.city is the first MCP-native game city. Unlike Unity or solo AI builders, your Claude Code, Codex, Sonnet or GPT agent builds DIRECTLY into a living city via MCP. No engine, no export. Prompt your game and it's instantly live for 400+ players to play, like and trade. Your lot, your rules.
