Connect Just Publish to ChatGPT

Add Just Publish as a connector in ChatGPT (Developer Mode) so you can ask ChatGPT to put the site it built for you online.

← All ways to connect

Connect in a couple of minutes

Turn on Developer Mode
In ChatGPT on the web, go to Settings → Apps → Advanced settings and enable Developer mode. (Available on Plus, Pro, Business, Enterprise, and Edu plans.)
Create a custom connector
Go to Settings → Connectors → Create. Give it a name (for example “Just Publish”) and a short description, and set the Connector URL to https://mcp.justpublish.ai/.
Choose the auth type
Select No Authentication — Just Publish's publish flow doesn't require sign-in. Save the connector.
Use it in a chat
In a new chat, enable the Just Publish connector, then ask ChatGPT to publish your site.

Verified against OpenAI — Connect from ChatGPT. Client menus can change — if a label looks different, look for the connector / MCP settings and add the URL https://mcp.justpublish.ai/.

Try it

Once connected, ask ChatGPT:

Test prompt ChatGPT

Build a simple one-page site for a coffee shop and publish it — then give me the link.

The tools ChatGPT gets

Just Publish exposes three tools — nothing else:

Tool	What it does
`deploy` Publish a website	Send the static files (HTML, CSS, JS, images) and get back a live URL, a site_id, and an edit_token. A later deploy with the same site_id + edit_token replaces the whole site.
`get_site_files` Read a published site's files	Read the current files of a published site (with its version), so the assistant can see what's live before changing it.
`update_site_file` Edit specific files of a published site	Change one or a few files on an existing site without re-sending the whole thing — the merge never deletes the files you leave out.

A first deploy creates the site and returns an edit_token; keep it — it's how ChatGPT edits the site later with update_site_file (or replaces it with another deploy).

When to use it — and when not

Good fit

ChatGPT built you a static page (or you pasted one in) and you want it live at a shareable link, straight from the chat.

Not a fit

You want ChatGPT to run backend code, a database, or a login for you — that's outside what a published static site can do.

If something's off

You don't see “Developer mode” in settings.
It's a web feature on paid plans — open ChatGPT in a browser (not the mobile app) and check Settings → Apps → Advanced settings.
The connector won't connect to the URL.
Confirm the URL is exactly https://mcp.justpublish.ai/ (with the trailing slash) and that you chose the “No Authentication” option.

Limits

Just Publish serves static sites only — HTML, CSS, JavaScript, images, and fonts. No servers, databases, logins, or build steps. Sites go live at a shareable URL, and you can connect your own custom domain when you're ready.
