## Why search_contacts_by_group is rated Low

This tool retrieves or queries contact data filtered by group, with no side effects. It matches the Read category (search, list, get, fetch operations). Severity is low because contact metadata is generally low-sensitivity information, and the operation is non-destructive. Confidence is 0.85 rather than higher because the tool description is empty, requiring inference from context and sibling tools.

From the tool's own definition: "Tool name 'search_contacts_by_group' indicates querying/filtering contacts by group membership. Server description confirms this is part of 'searching' contacts functionality."

## Use case

AI agents call search_contacts_by_group 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.
