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.

Waydev has relaunched as the measurement layer for AI-written code, letting engineering teams track which AI agent wrote which code, tokens consumed per PR, cost-per-shipped-line, and acceptance rates — with a unified comparison dashboard across GitHub Copilot, Cursor, Claude Code, and other AI coding tools. Founded in 2017 and backed by Y Combinator (W21), Waydev spent nine years building engineering analytics infrastructure. The pivot to AI SDLC measurement uses that existing integration surface (GitHub, GitLab, Jira, Linear) to add agent attribution metadata on top of existing flow metrics. The result is the first tool that can answer 'our team spent $4,200 on AI coding tools last month — which $1,000 was actually worth it?' With enterprise engineering budgets now routinely including five-figure monthly AI tooling costs and no standardized way to measure output quality by tool, Waydev's timing is sharp. The YC pedigree and existing customer relationships mean this isn't starting from zero — they're adding a new measurement layer to existing installed base.
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.”
“The 'which AI tool actually shipped good code' question is one every eng manager is asking. Waydev's existing Git integration means the attribution layer isn't a cold-start problem — if you're already using it for velocity metrics, the AI measurement upgrade is an obvious yes.”
“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.”
“Measuring AI contribution by tokens or accepted suggestions is a proxy for value, not value itself. Code quality, bug rates, and time-to-review are better signals, and those are already available in existing tools. Enterprise pricing with no numbers on the website signals this is expensive; wait for a published case study with real ROI data.”
“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.”
“As AI coding tools proliferate, the meta-layer question becomes 'which tool compound returns the best for which task type and team composition?' Waydev is building the dataset that will eventually answer that — and the company that owns that benchmark data owns significant influence over enterprise AI tool purchasing decisions.”
“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.”
“For creative technologists who switch tools constantly by feel, a measurement dashboard adds overhead that slows down experimentation. The ROI framing is enterprise-first; indie builders will be better served by just trying tools and shipping.”
