OpenAI opened a 10-day WebMCP hackathon with Chromium, Cloudflare, Shopify, Vercel, Render, and Netlify. WebMCP is an experimental open standard that lets web apps expose page-level tools agents can call. ChatGPT desktop built-in browser and ChatGPT Sites are adding WebMCP support so ChatGPT or Codex can use compatible sites automatically.
