Connect Just Publish to Cursor

Connect Just Publish to Cursor so it can publish the static site you're working on and hand you a live link — right from the editor.

← All ways to connect

Connect in a couple of minutes

Open Cursor's MCP settings
In Cursor, go to Settings → Tools & MCP and choose “New MCP Server”. That opens your mcp.json (global at ~/.cursor/mcp.json, or per-project at .cursor/mcp.json).
Add Just Publish as a remote server
Paste the configuration below (Cursor recommends Streamable HTTP for remote servers — that's what Just Publish uses). Save the file.
Confirm it connected
Back in Settings → Tools & MCP, Just Publish should show its tools. If it doesn't, open the Output panel and pick “MCP” to see the connection log.

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

Configuration

Paste into mcp.json Cursor

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

Try it

Once connected, ask Cursor:

Test prompt Cursor

Publish this site and give me the live link.

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

When to use it — and when not

Good fit

You're building a static site in Cursor (HTML/CSS/JS/images) and want to put it online without leaving the editor or setting up hosting.

Not a fit

Your project needs a server, database, login, or a build step to run — Just Publish serves static files only.

If something's off

The server doesn't appear after saving mcp.json.
Check the JSON is valid (no trailing commas) and that the URL is exactly https://mcp.justpublish.ai/ — then reopen Settings → Tools & MCP.
Cursor asks for an API key or header.
None is needed — Just Publish's publish flow is unauthenticated. Leave headers out entirely.

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.
