DOOM running in ChatGPT and Claude
A developer has created a playable version of DOOM that runs inline within AI clients like ChatGPT and Claude using MCP (Model Context Protocol) apps, with a fallback to a browser URL for unsupported platforms. The implementation uses a lightweight server, WebAssembly, and signed tokens to enable seamless gameplay across environments.
