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.

GroqCloud MCP Server

Route MCP tool calls through Groq's LPU hardware for sub-100ms latency

Groq's official open-source MCP server lets any MCP-compatible agent framework route tool calls through GroqCloud's LPU inference hardware. The pitch is sub-100ms response times for tool-calling workflows, which matters when agents are chaining dozens of calls in sequence. It's available on GitHub with no proprietary lock-in beyond using Groq's inference backend.

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 primitive here is clean: an MCP server that proxies tool calls to Groq's inference API, letting you swap in LPU-backed latency without rewriting your agent framework. The DX bet is correct — keep the MCP protocol as the abstraction layer, make Groq a drop-in transport. First 10 minutes test: clone the repo, set one env var (GROQ_API_KEY), point your MCP client at it, done. That's the right complexity budget. The specific decision that earns the ship is that they shipped actual open-source code instead of a hosted wrapper with a dashboard — you can read what it does, fork it, and trust it.

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.

Category is MCP server for LLM inference routing; direct competitors are running your own Ollama instance or just calling the OpenAI-compatible Groq REST API directly, which most frameworks already support. The specific scenario where this breaks: if Groq's API has a bad latency day or rate-limits you, your entire agent's tool-calling pipeline stalls with no obvious fallback in the protocol. What kills this in 12 months is not a competitor — it's that every major agent framework ships native Groq support and the MCP server becomes redundant infrastructure. Still, for teams already committed to MCP as their agent abstraction layer, this is the right interface and the open-source release is the right move.

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.

80/100 · ship

The thesis: multi-step agent workflows live or die on per-call latency, and the cumulative tax of 500ms-per-call across 20 tool invocations is the actual bottleneck preventing agentic systems from feeling responsive. That's a falsifiable, mechanical claim — not vibes. What has to go right: MCP needs to become the dominant agent-tool protocol, and Groq's LPU advantage needs to hold as GPU inference continues to get faster; both are non-trivial dependencies. The second-order effect nobody's talking about is that sub-100ms tool calling changes how developers *design* agents — you start building workflows with 40 hops instead of 4 when latency stops being a constraint, which creates a new class of application that simply wasn't practical before. This is early on the MCP infrastructure trend, which is exactly where you want to be.

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.

The buyer here is a developer or platform team already using MCP, which is a narrow slice of a narrow slice. The pricing is pure consumption — every token goes to Groq's revenue line, and the MCP server itself is open source with no monetization surface of its own, so this is customer acquisition for GroqCloud, not a standalone business. The moat question is real: Groq's only defensible position is LPU hardware performance, and if NVIDIA closes the inference latency gap or Cerebras scales faster, the entire value proposition evaporates. I'm skipping not because the product is bad but because as a business bet this is a distribution play for GroqCloud dressed up as a developer tool release — the unit economics only work if it drives meaningful token volume, and MCP adoption isn't there yet to justify that bet.
