# Share a page Cursor built: publish HTML from Cursor to a private link

> Add the Outbox MCP server to Cursor's mcp.json and the agent publishes prototypes, design docs and reports as private, versioned pages you can send to a client.

Cursor's agent can build a clickable prototype or a design doc in minutes. Showing it to a client usually means deploying a whole project or recording a video. With Outbox the agent publishes the page itself and hands you a private link.

## Set it up with the local MCP server

1. In Outbox, create an API key under Settings → Keys. Scope it to a folder, for example `prototypes`.
2. Add the server to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (one project) with the config below.
3. Open Cursor Settings → MCP and check that outbox is enabled and its tools are listed.
4. In the agent chat: "publish this page to my Outbox as prototypes/checkout-v2".

~/.cursor/mcp.json:

```
{
  "mcpServers": {
    "outbox": {
      "command": "npx",
      "args": ["-y", "@out-box/mcp"],
      "env": {
        "OUTBOX_API_KEY": "outbox_xxxxxxxx",
        "OUTBOX_TOOLSETS": "core,comments,sharing"
      }
    }
  }
}
```

Keep the key out of the repo: prefer the global `~/.cursor/mcp.json`, or add the project file to `.gitignore`.

## Or use the skill

Cursor is one of the agents supported by `npx skills`. The skill teaches the agent the publish, read and share loop and connects your account with a link the first time:

```
npx skills add jonathanleiva15/out-box-skills
```

## Make the page publishable

Outbox serves one HTML document per page. Ask Cursor to inline the CSS and JavaScript into a single self-contained file; images can be uploaded separately (PNG, JPEG, GIF or WebP) and referenced by URL. Multi-file builds with a server or a database are a better fit for app hosting.

## What people publish from Cursor

- A UI prototype for client sign-off, shared with a [link per stakeholder](https://out-box.dev/en/per-recipient-links) so you know who looked at it.
- An architecture or design doc generated from the codebase, republished as the code changes.
- A before/after page for a refactor, for reviewers outside the engineering team.

## Frequently asked questions

### Can I use the remote connector in Cursor?

The setup we document for Cursor is the local server with npx. The remote connector is documented for Claude clients.

### Will the client see changes I make later?

Yes. When the agent republishes to the same slug, the link shows the new version and the old one stays in the history.
