Show HN: Play Hide and Seek vs. a Self-Improving Agent Using WebMCP (lightcone-webmcp.netlify.app)

Hey, built a small game to learn about the WebMCP standard. Use the Codex app, start a new chat in Work mode using Sol or Terra, open the built-in browser (cmd+shift+b), navigate to the url, and paste these instructions "Play the WebMCP game at https://lightcone-webmcp.netlify.app/. Read the briefing tool first, then start playing when you're ready."
