DOOM runs in ChatGPT and Claude
Summary
Chris Nager demonstrates a playable DOOM MCP app that runs inline inside AI chat clients like ChatGPT and Claude, with a fallback to a browser URL. The project highlights a lean, self-contained architecture using a signed token for launching and addresses cross-client rendering challenges by rendering the DOOM canvas directly in the host iframe. It serves as a practical example of embedding interactive tool apps inside AI copilots, with attention to security and deployment considerations.
