WHAT IT DOES

What list_contact_groups does on MCP Google Contacts Server

AI agents call list_contact_groups to retrieve information from MCP Google Contacts Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_contact_groups is rated Low

The tool appears designed to retrieve and list existing contact groups without modifying, deleting, or executing operations. Despite the empty description, the name 'list_' is a strong indicator of a read-only operation that queries contact group data. The severity is low because it only retrieves organizational data with no side effects.

From the tool's definition Tool name 'list_contact_groups' and server description indicating it provides 'managing contact groups' and 'accessing Google Workspace directories' suggests retrieval of contact group data.
