list_folder_contents
AI agents call list_folder_contents to retrieve information from Google Docs MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
List operations are read-only and retrieve data with no side effects. This tool queries the contents of a folder in Google Drive without creating, modifying, or deleting any files. The blast radius of misuse is limited to information disclosure of folder structure and filenames the requester already has access to.
From the tool's definition Tool name 'list_folder_contents' indicates a retrieval operation that lists directory contents without modification. The server description confirms it 'manages Google Docs and Drive files' with operations including 'read' and 'list'.
