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's Agent Development Kit (ADK) just hit two major milestones simultaneously: ADK Python 2.0 Beta with workflows and agent teams, and ADK TypeScript 1.0 reaching stable release. This open-source framework is Google's answer to LangChain and CrewAI — a code-first toolkit for building production-grade AI agents that are testable, versionable, and deployable anywhere. What separates ADK from the competition is its context management philosophy: it treats sessions, memory, tool outputs, and artifacts like source code, assembling structured context where "every token earns its place." The 2.0 beta introduces graph-based workflows and collaborative multi-agent systems, letting developers compose teams of specialized agents into complex hierarchies. It's model-agnostic despite being optimized for Gemini, and supports MCP natively. Deployment is a first-class citizen — native integrations with Cloud Run, GKE, and Vertex AI Agent Engine, plus Google's new Agents CLI for scaffolding, eval, and deploy in one command. With Apache 2.0 licensing and a bi-weekly release cadence, this is shaping up as the enterprise-grade foundation serious agent builders have been waiting for.
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.”
“Graph-based workflows in 2.0 Beta finally make multi-agent orchestration feel sane. The Agents CLI scaffolding saves an hour of boilerplate every new project. Apache 2.0 means no licensing headaches at scale.”
“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.”
“It's 'model-agnostic' but the Cloud Run and Vertex AI integrations make it a Google Cloud lock-in play dressed in open-source clothing. LangGraph and CrewAI have a 2-year head start and larger ecosystems — ADK needs to prove itself outside Google's walls.”
“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.”
“ADK being 'designed to be written by both humans and AI' is the key insight here — we're entering an era where agents build agents, and ADK is building the scaffolding for that recursion. TypeScript 1.0 stable means the frontend ecosystem is now fully in play.”
“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.”
“Visual debugging and evaluation frameworks finally make agent behavior legible — no more blind faith in what your agent actually did. This lowers the floor for non-ML engineers to build reliable agent pipelines.”
