Which exact service and endpoints does this utilize?

This integration leverages the highly structured Google People API. It strictly filters and returns core metadata (emails, names, numbers) avoiding unnecessary heavy payloads.

Can it automatically assign new prospects into specific mailing groups?

Certainly. The `create_contact` tool allows passing a specific Group Identifier (which you can discover using `list_contact_groups`). The user will instantly appear in the matching mailing segment.

What happens if I try to list a corporate directory with thousands of interconnected contacts?

The integration is protected by aggressive egress control pagination features out-of-the-box. Your AI agent handles paginated loops automatically and queries intelligent searches to restrict context overhead limits naturally.

Is it possible to manage shared domain profiles or only my personal Gmail connections?

Assuming you are logged in using a Google Workspace suite, the authorization supports cross-referencing domain contacts. Personal Gmail queries apply strict visibility bounding towards individual connections only.
