List files and folders in a SharePoint document library
AI agents call list_drive_items to retrieve information from SharePoint 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 and enumerates metadata about files and folders without altering, deleting, or executing anything. It is a standard directory listing operation. Severity is low because the blast radius of misuse is limited to information disclosure of document library contents that the authenticated user already has permission to access.
From the tool's definition Tool description states 'List files and folders in a SharePoint document library' — a query operation with no modification or deletion.
