About vibe-fun

vibe-fun is an open-source game server for the age of AI assistants. It delivers polished, self-contained HTML games to any host that speaks the Model Context Protocol's MCP Apps extension — so the same game you play in your browser can play right inside ChatGPT or Claude.

Why it exists

Game portals are invisible to the assistant you actually talk to, and one-off chat apps are locked to a single game and host. vibe-fun is the layer in between: a shared catalog that travels with you. Connect once, and every game shows up — add a new game and it reaches every connected host at once, with no client update.

Open source

vibe-fun is free and open source under the MIT license. The whole server, the games, and the reference host all live in one repository — adding a game is a single self-contained HTML file. Contributions and new games are welcome.
