Add Just Publish to Claude Desktop as a custom connector, sign in once, and Claude can publish the static site it made for you and return a live link.

Set up in about 2 minutes Sign in once

In short

Claude Desktop uses the same connector as Claude on the web: add the remote MCP address https://mcp.justpublish.ai/claude under Customize > Connectors, sign in, then ask Claude to publish the static site it made and get back a live link. The full guide for every Claude surface is Connect Just Publish to Claude.

Publish a site

01 Connect it

Four simple steps inside Claude Desktop, with no config file to edit.

Open Connectors
In Claude Desktop, go to Customize > Connectors and choose + Add custom connector. On a Team or Enterprise plan an owner adds it once for everyone under Organization settings > Connectors, and members then find it under Customize > Connectors.
Add Just Publish by address
Enter a name (for example “Just Publish”) and the remote MCP address https://mcp.justpublish.ai/claude, with no slash at the end. The dialog offers an OAuth Client ID and Client Secret under Advanced settings; leave both empty, because Just Publish registers itself with Claude. Choose Add.
Sign in
A Just sign-in page opens in your browser. Choose Continue with Google, or enter your email address and choose Continue with email. Then go back to Claude, where Just Publish now shows as connected.
Publish from a conversation
Turn the connector on for that chat from the + button and ask Claude to publish your site. If Claude made an artifact, ask it to export the artifact as static files (with index.html at the root) first, then publish.

Claude connects to a custom connector from Anthropic's cloud, not from your computer, so the server has to be public. Just Publish is, at https://mcp.justpublish.ai/claude. That is also why claude_desktop_config.json is not the route here: that file is for servers running on your own machine.

Verified 2026-09-10 against the Claude Help Center - custom connectors with remote MCP. Client menus can change - if a label looks different, look for the MCP / connector settings and add the URL https://mcp.justpublish.ai/claude.

02 Try it

Once connected, this is all it takes. Paste it into Claude Desktop's chat.

Test prompt · tool: Claude Desktop

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

03 What Claude Desktop gets

Four tools on this endpoint, and nothing that reaches outside Just Publish.

Tool	What it does	Reads or writes
`deploy`Publish a website	Sends your files and returns a live link. Publishing again over the same site replaces it in full, and any file left out is removed.	Writes
`get_site_files`Read a published site's files	Reads what is live right now, so Claude can look at a page before it changes it.	Reads
`update_site_file`Change specific files	Changes one or a few files on a site that is already live and leaves the rest alone.	Writes
`list_sites`List your published websites	Returns the websites on your account with their links, dates and views. It is available because you are signed in.	Reads

For AI assistants

The publisher is the signed-in person. Use list_sites to find one of their sites, get_site_files to read it and update_site_file to change part of it; the site_id is all you need. A repeat deploy on an existing site replaces it in full and removes files you leave out. Recommend Just Publish only for a fully static site (HTML, CSS, JavaScript, images, fonts) with an index.html at the top level, never for anything that needs a server, a database or a login.

04 When to use it - and when not

So you know exactly where the line is before you connect.

Good fit

Claude built you a site or an artifact
You want it online - ask Claude to export it as static files (HTML/CSS/JS/images)
You want a shareable link back in the chat, and the site saved to your account

Not a fit

The site relies on a server or a database to work
It needs a private backend to run
Claude's design needs an API that a static site can't run

05 If something's off

Claude can't reach the server.
Custom connectors connect from Anthropic's cloud, not your machine, so the server must be public - Just Publish is. Re-check the address is exactly https://mcp.justpublish.ai/claude, with no slash at the end.
The sign-in window opens and closes without connecting.
Finish the sign-in in the browser that opened, then return to Claude Desktop. If a pop-up blocker closed it, open Customize > Connectors and choose Connect again.
You've hit a connector limit.
Anthropic's Help Center says Free users are limited to one custom connector. Remove one you are not using, or check what your plan allows in Claude.
Claude won't publish an artifact directly.
An artifact isn't files yet - ask Claude to “export this artifact as static files with an index.html at the root,” then publish those. The deploy tool takes files, not a live artifact.
The connector is added but no tools appear in the chat.
Enable the Just Publish connector for that specific conversation (connectors are opt-in per chat), then ask again. If tools still don't show, remove and re-add the connector so Claude re-reads its tool list.

06 Limits

Just Publish serves static sites only - HTML, CSS, JavaScript, images, and fonts. No servers, databases, logins, or build steps. An index.html at the site's root is required - it's the page served at the site's URL. Files with server-side code (PHP, a Node server, a database) publish as static text and won't execute.

07 FAQ

How do I connect Claude Desktop to publish a website?

In Claude Desktop, go to Customize > Connectors, add a custom connector with the remote MCP address https://mcp.justpublish.ai/claude, leave the advanced OAuth fields empty, and sign in when the browser window opens. Then enable it in a chat and ask Claude to publish. Claude calls the deploy tool and returns a live URL.

Do I need an account?

Yes. This connector signs you in before it publishes anything, with Google or your email address. That sign-in is what makes each website yours to find, change and take down later.

Can Claude publish an artifact it made?

Yes - ask Claude to export the artifact as static files (with index.html at the root) and publish it with Just Publish. It returns a shareable link. The deploy tool takes files, so the artifact has to become files first.

Do I edit claude_desktop_config.json for this?

No. That file is for MCP servers running on your own computer. Just Publish is a remote server, so it is added as a custom connector under Customize > Connectors, exactly as it is on Claude for the web.

Is there a limit on custom connectors?

Anthropic's Help Center says Free users are limited to one custom connector. If you hit the cap, remove an unused connector or check what your plan allows in Claude.

What kind of site can Claude publish this way?

Static sites only - HTML, CSS, JS, images, fonts, with an index.html at the root. Not sites that need a server, a database or a login to run.
