## Configuration

The Configuration tab in the Agen for SaaS control plane manages the core settings for your MCP server. It is divided into two collapsible sections: **Basic configuration** and **Allowed origins**.

### Basic configuration

The basic configuration section contains the following settings:

| Field | Description | Editable |
|  --- | --- | --- |
| **Server name** | The display name for your MCP server (e.g., "Expense Management App"). This is a required field. | Yes |
| **MCP Gateway URL** | The auto-generated endpoint where AI agents connect to your MCP server (e.g., `your-id.mcp-gw.frontegg.com`). Includes a copy button for easy sharing. | No (read-only) |
| **Custom domain** | An optional custom domain mapped to your MCP Gateway. Displays "No domain configured" when not set. | Yes (via Configure button) |


Click **Save** to apply changes to the server name, or **Cancel** to discard.

### Custom domain setup

To configure a custom domain for your MCP Gateway:

1. Click the **Configure** button below the Custom domain field.
2. In the **Configure custom domain** dialog, a two-step wizard guides you through the process:


**Step 1: Add domain**

- Enter your desired domain in the **Domain** field.
- Click **Next** to proceed.


**Step 2: DNS records**

- The wizard displays the DNS records (CNAME entries) you need to add to your domain's DNS configuration.
- Add these records through your DNS provider.
- Once DNS propagation completes, Agen for SaaS verifies the domain automatically.


Click **Cancel** at any point to exit the wizard without changes.

### Allowed origins

The Allowed origins section controls which web origins can access your Agen for SaaS application. Access is enforced by the `Origin` HTTP header.

By default, two origins are pre-configured:

- `{{APP_URL}}` — Your application's URL.
- `{{LOGIN_URL}}` — Your login page URL.


Each origin entry has a delete button (trash icon) to remove it.

To add an origin:

1. Click **+ Add new origin**.
2. Enter the origin URL.
3. Click **Save**.


Changes to allowed origins take up to **5 minutes** to take effect.
