Spins up static sites from zip files you send over MCP. You reserve a subdomain, push your HTML/CSS/JS bundle through the protocol, and get back a live URL served through Nginx. No server-side execution, no databases, no PHP. Useful when you want Claude to generate a complete static site (landing page, documentation, portfolio) and deploy it immediately without leaving the conversation. The streamable-http transport means it handles file uploads directly. Think of it as a deployment target for any workflow where Claude is authoring front-end code and you want to see it live in seconds rather than explaining how to use Netlify or Vercel.
