TL;DR · WeSearch summary

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.

Key facts

▪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.
