# Installed Application Settings

Installed applications can be customized with their own settings.

To edit the settings for an installed application, select the "Edit Settings" button within the application card in Vertesia Studio (`Vertesia Studio > Settings > Applications > Installed Apps`).
- Note: If you do not have permission to edit the application, you will not be able to make changes.

## OAuth Credentials at Install Time

If an app's manifest declares MCP collections with [`oauth_config.required_at_install`](/apps/tool-collections#embedded-oauth-configuration), Vertesia displays a credential form before completing the installation. Required fields may include:

| Field | Description |
| ----- | ----------- |
| **Client ID** | Your OAuth client identifier, if each project registers its own client with the provider. |
| **Client Secret** | Your OAuth client secret. Secrets are encrypted at rest and never stored in the manifest. |
| **Scopes** | Additional OAuth scopes to request, added on top of the manifest's `default_scopes`. |

After install, the OAuth provider created from these credentials can be viewed and updated in **Project Settings > OAuth Providers**.
Install-time credentials are associated with each MCP collection by its stable `id`, not its display `name`.

## App Card Color

You can customize the colors used for the application card's appearance within the Vertesia App Portal. To do so, use the `color` property in the application settings:

```json
{
  "color": "<color_name>"
}
```

### Available Colors

When configuring application installations, you can choose from a variety of predefined colors to customize your applications's appearance:

  red
  orange
  amber
  yellow
  lime
  green
  emerald
  teal
  cyan
  sky
  blue
  indigo
  violet
  purple
  fuchsia
  pink
  rose

### Using Color Gradients

Applications support two different gradient formats for enhanced visual appearance:


### Using Gradient Stops

Gradients can be specified using color names with numeric gradient stops:

  - **Format:** `color-number`
  red-0
  red-1
  red-2
  red-3
  red-4


### Using Two Colors

Create gradients that blend between two different colors:

  - **Format:** `color-color`
    red-red
    red-orange
    red-amber
    red-yellow
    red-lime
