Search
AI agents call searchPeopleOtherContacts to retrieve information from Google Workspace MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches or retrieves people/contacts from Google Workspace's 'Other Contacts' directory. Search operations are read-only with no side effects—they query existing data without creating, modifying, deleting, or executing external operations. The minimal blast radius if misused is unauthorized information disclosure of contact details, which is a low-severity risk.
From the tool's definition Tool name 'searchPeopleOtherContacts' and description 'Search' indicate a query operation that retrieves contact information without modifying data.
