This guide shows you how to configure the ZoomInfo 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 Control Center under Integrations > Connectors. The ZoomInfo connector requires organization-managed OAuth—you must create your own MCP app in the ZoomInfo Developer Portal to connect.
Creating an MCP app requires a DevPortal subscription, assigned by your ZoomInfo admin.

​
Create a ZoomInfo MCP app

Create an MCP app in the ZoomInfo Developer Portal:
  1. Go to the ZoomInfo Developer Portal 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:
    If your organization is deployed in the EU, use https://app.eu2.writer.com/mcp/oauth/callback instead.
  6. Select Create
  7. Open the app and copy the Client ID and Client Secret—you’ll need these when connecting the connector in Control Center

​
Configure the connector in Control Center

Complete the following steps in Control Center:
  1. Navigate to Integrations > Connectors in Control Center, 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
