Connect Just Publish to Claude Desktop

Add Just Publish as a custom connector in Claude so Claude can publish the site it made for you and return a live link.

Connect in a couple of minutes

Open Connectors
In Claude, go to Settings → Connectors (via Customize → Connectors) and click the “+” to add a custom connector.
Add Just Publish by URL
Enter a name (for example “Just Publish”) and the remote MCP URL https://mcp.justpublish.ai/. Leave the OAuth advanced settings empty — no sign-in is needed. Click Add.
Publish from a conversation
Enable the connector in a chat and ask Claude to publish your site. (Custom connectors are available across Claude's plans.)

Verified against Claude — custom connectors (remote MCP). 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 Claude Desktop:

Test prompt Claude Desktop

Export this as static files and publish it with Just Publish, then give me the link.

The tools Claude Desktop 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 Claude Desktop edits the site later with update_site_file (or replaces it with another deploy).

When to use it — and when not

Good fit

Claude built a site or artifact for you and you want it online — ask Claude to export it as static files and publish it.

Not a fit

The site relies on a server, database, or login to work — a published static site can't run those.

If something's off

Claude can't reach the server.
Custom connectors connect from Anthropic's cloud, not your computer, so the server must be public — Just Publish is. Re-check the URL is exactly https://mcp.justpublish.ai/.
You've hit a connector limit.
Some Claude plans cap how many custom connectors you can add; remove an unused one if you reach the limit.

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.
