Open-source MCPsfor game engines.
Give Claude Code, Cursor, Codex — and any MCP client — native control of Unity, Godot, and Cocos Creator. Plus a skills library for the art, audio, and level workflows in between.

Open source. MIT licensed.
Everything here is MIT. No signups, no seats, no quotas. Use it at home, at a studio, ship commercial games with it — all four repos are free forever.
Unity 2022.3+ · Godot 4.2+ · Cocos 3.8+
Editor-only installs. Nothing ships in your player build — MCP runs next to the editor, not inside the game.
Local HTTP, port fallback
Default 127.0.0.1:8765. Port busy? Funplay MCP picks the next free one and updates your client config.
Register your own tools
Attribute-based tool discovery in every engine — add a method, it becomes callable from any MCP client on the next compile.
