Just Publish
Guide

Publish a site from Claude.

You built a site with Claude. You want a live URL without touching git, a CLI, or a build step. Add one MCP endpoint to Claude Desktop and Claude publishes for you.

01

Add the MCP endpoint to Claude Desktop

Open Claude Desktop → Settings → Developer → Edit Config. Paste the snippet below and restart Claude.

{
  "mcpServers": {
    "just-publish": {
      "url": "https://mcp.justpublish.ai/"
    }
  }
}
02

Ask Claude to publish

In any conversation, paste a prompt like:

Publish this HTML to Just Publish and give me the URL.

Claude calls the deploy tool with your files. The first time, it'll ask for your email — used only so you can recover the site later.

03

Get your URL back in the chat

Claude returns a URL like https://xK3p9wnA2b.just-web-hosting.com/. The site is live the moment it responds — share it with anyone.

To update the site later, tell Claude "update the site at <URL> with these new files". Claude remembers the edit token from earlier in the conversation; the update happens in place.

What you can publish

Static files only — HTML, CSS, JS, images, fonts. There's no build step, no SSR. Frameworks that produce a static export (Astro, Eleventy, Hugo, Next.js export, Vite) work because they output static files. Max site size 50 MB, max single file 5 MB, index.html at the root required.
