DOOM running in ChatGPT and Claude
DOOM can now be played within AI platforms like ChatGPT and Claude through a new MCP (Model Context Protocol) application. The implementation uses a lightweight server and browser-based DOOM runtime, enabling inline gameplay where supported and falling back to a standard web link otherwise. The project leverages existing web technologies and security measures to maintain compatibility across different AI clients.
- ▪An MCP app has been developed to run DOOM inline within AI clients such as ChatGPT and Claude.
- ▪The app uses cloudflare/doom-wasm to run DOOM in the browser and relies on a signed token system for session management.
- ▪It supports progressive enhancement by providing a fallback URL for clients that do not support inline UI rendering.
- ▪Security policies and iframe restrictions posed significant challenges during the development of the inline app experience.
- ▪The project uses Freedoom Phase 1 as its default content to ensure the game remains redistributable.
