# ZoomInfo connector

> Connect WRITER Agent to ZoomInfo to research companies and contacts, and access intent and signal data

This guide shows you how to configure the [ZoomInfo](https://www.zoominfo.com/) connector for WRITER Agent. After setting up this connector, WRITER Agent can look up reference data, enrich company signals, and access intent data to support your go-to-market research.

## Set up the ZoomInfo connector

Configure the ZoomInfo connector in [AI Studio](https://app.writer.com/aistudio) under **Connectors & Tools**. The ZoomInfo connector requires organization-managed OAuth—you must create your own MCP app in the ZoomInfo Developer Portal to connect.

<Note>
  Creating an MCP app requires a DevPortal subscription, assigned by your ZoomInfo admin.
</Note>

### Create a ZoomInfo MCP app

Create an MCP app in the ZoomInfo Developer Portal:

1. Go to the [ZoomInfo Developer Portal](https://developer.zoominfo.com/) and sign in, or open the **API/MCP** tab in the left navigation of the ZoomInfo app

2. Select **Create App**

3. Enter an app name (this name appears on the consent screen users see when they sign in)

4. Select **MCP App** as the app type—this automatically assigns the required data scopes, so no manual scope selection is needed

5. Add the Writer redirect URI to the app's redirect URIs:

   ```
   https://app.writer.com/mcp/oauth/callback
   ```

   <Note>
     If your organization is deployed in the EU, use `https://app.eu2.writer.com/mcp/oauth/callback` instead.
   </Note>

6. Select **Create**

7. Open the app and copy the **Client ID** and **Client Secret**—you'll need these when connecting the connector in [AI Studio](#configure-the-connector-in-ai-studio)

### Configure the connector in AI Studio

1. Navigate to **Connectors & Tools** in [AI Studio](https://app.writer.com/aistudio), search for **ZoomInfo**, and select the connector
2. Select who has access by default (all teams or specific teams)
3. Select the connection type:
   * **Level**: User level (each user authenticates their own account) or org level (one OAuth connection shared across your organization)
   * **Managed by**: Self managed (your own OAuth app)
4. Select which tools can be used by default
5. Confirm the redirect URL matches the one you added to your ZoomInfo MCP app, then enter your OAuth client ID and client secret
6. Complete the OAuth authorization flow to connect to ZoomInfo
