coop-anything

Co-op Anything is an MCP server and playbook that lets you point an AI agent at any single-player game and play it with friends, online, in splitscreen, or both. Its purpose is to add co-op play to games built for one player.

The playbook covers a loop of reverse engineering a game, fixing and testing what the agent finds, shipping the result, and sharing what it learns. Full details are at coopanything.app.
