Chris Nager built a fully playable DOOM that runs as an MCP (Model Context Protocol) app, rendering inline inside Claude and ChatGPT without a separate browser tab. The architecture uses two MCP tools — create_doom_session for inline-capable hosts and get_doom_launch_url as a browser fallback — combined with cloudflare/doom-wasm for the game runtime and a signed token system that maintains session state across both surfaces. The result is the same session whether you're playing inline or in a tab. The key technical challenge was avoiding iframe and CSP (Content Security Policy) issues. Rather than embedding a browser page inside the MCP iframe, the DOOM canvas runs directly inside the host's iframe — a subtle but critical distinction that resolved a class of rendering and input-handling bugs. The final implementation is intentionally stripped down: no save/load, no persistence adapters, just stable playable DOOM. Beyond the novelty, this project is a concrete demonstration that MCP apps are interactive surfaces, not just tool-calling JSON endpoints. The progressive enhancement pattern — same signed-token foundation serving both inline and browser modes — is a reusable architecture for any game or interactive experience that wants to live inside an AI assistant. Nager open-sourced the implementation and the blog post is a detailed technical breakdown.

Google has released Android CLI, a terminal-first developer SDK designed to dramatically reduce friction for both human developers and AI agents building Android apps. The CLI bundles SDK management, project creation, emulator lifecycle control, and device management into a single command-line interface optimized for LLM token efficiency — completing tasks 3x faster than traditional tooling while using 70% fewer tokens. Two companion systems make the CLI agent-friendly: Android Skills (markdown instruction sets for common workflows — setting up Firebase, adding a dependency, configuring signing) that agents can follow step-by-step, and Android Knowledge Base accessible via 'android docs' which provides structured, up-to-date documentation directly in the terminal without web fetching. Combined, these dramatically reduce the hallucination rate in AI-generated Android code by grounding agents in authoritative current docs. The CLI is free, open source, and available for macOS, Linux, and Windows. It works with any AI coding agent — Claude Code, Codex, Cursor, Gemini CLI — and doesn't require any Google account for local development. Google positions it as the foundation of Android's agent-first developer experience, with deeper Gemini integrations planned for later in 2026.
Reviewer scorecard
“The signed-token progressive enhancement pattern is the part worth stealing. This is a clean reference architecture for MCP interactive apps, and DOOM just happens to be the demo case.”
“Android development has always had a painful amount of setup and boilerplate tooling. The token reduction numbers are plausible — most of the waste in AI-assisted Android dev comes from agents re-reading Gradle configs and SDK docs that should just be injected directly. The 'android docs' command for grounded documentation is the feature I'll use most.”
“Fun proof of concept but let's be honest: if your AI assistant is hosting a DOOM session, something has gone wrong with your productivity. The MCP-as-interactive-surface insight is real, but this specific app has no utility.”
“The 3x faster and 70% fewer tokens claims need independent benchmarking — Google set up the benchmark conditions and measured against their own traditional tooling baseline. Android's build system complexity doesn't disappear with a new CLI; Gradle and its dependency hell remain underneath. This feels more like a developer relations win than a fundamental improvement.”
“Every major compute platform's pivot point is when it runs DOOM. MCP running DOOM means MCP is a real platform now. The implications for interactive AI-embedded experiences are significant.”
“Platform vendors optimizing their tooling for AI agents is a trend that will compound significantly. Google shipping Android Skills as structured agent instructions means the next generation of Android apps will be largely agent-built. This is the beginning of a major shift in how mobile software is created.”
“As someone who thinks about interactive experiences, the idea of game-like UI living inside an AI context is genuinely exciting. This is a crude ancestor of what interactive AI-native media could become.”
“As someone who designs apps but doesn't live in Gradle configs, the idea that an AI agent can now build a functional Android app with significantly less scaffolding overhead is exciting. Lower barriers mean more creators can ship mobile apps without a dedicated Android engineer.”
