# How to Add a Connection

### Standard Connections

The **Available Connections** tab displays the standard connections supported by Duvo. Each connection card provides details on the connection's capabilities.

1. Click "Connect" on the desired connection

2. Complete the authentication steps for the application you're connecting to

The connection will appear in the "My Connections" tab making its tools available to your assignments.

### Custom Connections

These can be connected to Duvo in the "Available Connections" tab:

1. Click "+ Add Custom MCP" button

2. **Name**: Choose a descriptive name that identifies what system the connection is supporting
3. **MCP URL**: Enter the web address where your MCP server is hosted (e.g., `https://mcp.yourcompany.com/mcp`)
4. **Authorization**: Choose how Duvo should authenticate:
   * None: No authentication required
   * API Key: Provide an API key for authentication
   * OAuth: Use OAuth flow for authentication. Duvo automatically detects whether the MCP server supports **dynamic client registration (DCR)**. If it does, no Client ID or Secret is needed — the connection is handled automatically. If the server does not support DCR, or if you prefer to use your own pre-registered OAuth app, you can provide a Client ID and Client Secret in the **Advanced settings** section.
5. Click "Save"

Once configured, the custom connection will appear in your "My Connections" tab, making its tools available to your assignments.

### Editing Connection Credentials

To update a connection's credentials, open the connection from your "My Connections" tab and click **Edit**.

Sensitive fields such as API keys, passwords, and service account credentials are write-only. When you open an existing connection to edit it, these fields will appear empty — the stored credentials are not displayed for security reasons. Leave a field empty to keep the existing value, or enter a new value to replace it.
