demo.st

demo-stage/demo.st

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.

Install

From registry metadata

$ npx add-mcp https://demo.st/mcp --name demost --header 'Authorization: Bearer ${API_TOKEN}'

Run in your terminal. add-mcp asks which agents to add it to, then asks for each value it needs. Add -g to install it for every project.

Review the command, arguments and environment values before installing. MCP servers run with your local permissions.

Other ways

Claude Code

$ claude mcp add --transport http demost https://demo.st/mcp --header 'Authorization: YOUR_AUTHORIZATION'

Run in your terminal. Add --scope user to make it available in every project.
