Search for files and folders using Google Drive Query syntax
AI agents call gdrive_search to retrieve information from MCP Google Drive Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Search operations retrieve and query data without side effects. The tool only returns matching files and folders based on query syntax; it does not create, modify, delete, or execute code. This is a straightforward Read category tool with low severity since misuse would only reveal data visibility, not cause irreversible harm or financial impact.
From the tool's definition Tool name is 'gdrive_search' and description states it 'Search[es] for files and folders' — a query operation with no modification or deletion of data.
