You built a site with ChatGPT. Connect Just Publish as a custom MCP connector and ChatGPT publishes the files for you — the live URL comes back in the chat.
ChatGPT supports remote MCP servers on plans that allow custom connectors (currently Team, Enterprise, and Pro). Add a new connector with:
Server URL: https://mcp.justpublish.ai/
Authentication: NoneIf the connector option isn't available on your plan, use Claude Desktop or Cursor instead — same MCP endpoint, same tool, same result.
In any conversation, paste a prompt like:
Publish this site to Just Publish and share the URL.ChatGPT 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.
ChatGPT 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 ChatGPT "update the site at <URL> with these new files". ChatGPT remembers the edit token from earlier in the conversation; the update happens in place.
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.
