## Connect one

**1. Open the catalog**

Go to [**Settings → Connector Vault**](https://app.corvic.ai/settings/vault) and switch to **Available to connect**. Type the service's name in the search box, or filter by **API**, **OAuth**, **MCP**, or **Storage/Databases**.

**2. Pick the service**

Selecting a card prefills the host and the header the service expects. If the host is a placeholder such as `yourinstance…`, replace it with your own tenant's host.

**3. Paste your credential and save**

Enter the key or token in the format shown, choose whether the connector is for your organization or just for you, and save. Corvic tests the connection and shows its status on the card.
