universal-modder (fal MCP)

universal-modder is an open-source toolkit that gives AI coding agents (Claude Code, Codex, Cursor, Gemini CLI, OpenCode) the skills, a Python CLI called `um`, and a fal MCP server to mod almost any PC game you own. It covers the full modding loop: engine recon, reverse engineering, fal-generated art/3D/audio asset creation, in-game testing, and showcase video recording. Built by Rehan from real modding sessions on games like Terraria, Age of Empires II, and GTA V, and released under the MIT license.
