# Cursor Integration

Use Scalekit with Cursor via the local installer while the marketplace listing is under review
Use Scalekit with Cursor by running the local installer, enabling the auth plugin you need, and then prompting Cursor to generate the implementation in your existing codebase.

> note: Scalekit Auth Stack is under review on Cursor Marketplace
>
> The Scalekit Auth Stack plugin is currently under review and not yet live on [cursor.com/marketplace](https://cursor.com/marketplace). Once approved, you'll be able to install it directly with an "Add to Cursor" button.
>
> Until then, use the local installer to load the plugins into Cursor.

1. ## Install the Scalekit Auth Stack locally

   ```bash title="Terminal" frame="terminal" showLineNumbers=false
   curl -fsSL https://raw.githubusercontent.com/scalekit-inc/cursor-authstack/main/install.sh | bash
   ```

   This installer downloads the latest Scalekit Cursor plugin bundle and installs each auth plugin into `~/.cursor/plugins/local/<plugin-name>`.

   > tip: Use a symlink when iterating locally
>
> If you're developing the plugin repo locally and want changes to show up without recopies, use the local installer path described in the repository README to symlink plugins into `~/.cursor/plugins/local`.

2. ## Reload Cursor and enable the plugin

   Restart Cursor, or run **Developer: Reload Window**, then open **Settings > Cursor Settings > Plugins**.

   {/* IMAGE PLACEHOLDER: Screenshot of Cursor Settings > Plugins showing Scalekit Auth Stack */}

   Select the authentication plugin you need, such as **Full Stack Auth**, **Modular SSO**, or **MCP Auth**, and enable it.

   > note: Alternatively: Install via Skills CLI
>
> You can also install Scalekit skills with the Vercel Skills CLI:
>
> ```bash title="Terminal" frame="terminal" showLineNumbers=false
> npx skills add scalekit-inc/skills
> ```
>
> Use `--list` to browse available skills or `--skill <name>` to install a specific auth type. Refer to Cursor's documentation for how to invoke skills once installed.

3. ## Generate the implementation

   Open Cursor's chat panel with **Cmd+L** (macOS) or **Ctrl+L** (Windows/Linux) and paste in an implementation prompt. Use the same prompt from the corresponding Claude Code tab — the Scalekit plugins and their authentication skills work identically in Cursor.

   > caution: Review generated code
>
> Always review AI-generated authentication code before deployment. Verify that environment variables, token validation logic, and error handling match your application's security requirements.

4. ## Verify the implementation

   After Cursor finishes generating code, confirm all authentication components are in place:

   - The Scalekit plugin appears in **Settings > Cursor Settings > Plugins**
   - Scalekit client initialized with your API credentials (set up a `.env` file with your Scalekit environment variables)
   - Authorization URL generation and callback handler
   - Session or token integration matching your application's existing patterns

Once the Scalekit Auth Stack is live on [cursor.com/marketplace](https://cursor.com/marketplace), you'll be able to skip the local installer and install it directly inside Cursor.
