List all Google Docs in Drive
AI agents call list_documents 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 retrieves document listings from Google Drive with no side effects. It is a straightforward read operation analogous to 'list' or 'fetch'. The severity is low because listing documents poses minimal risk even if misused by an AI agent — it only exposes metadata about existing documents, not their contents or sensitive actions.
From the tool's definition Tool name is 'list_documents' and description states 'List all Google Docs in Drive' — a query operation that retrieves metadata about documents without modifying or executing any actions.
