List folders + files in one Drive folder (or root when folder_id is omitted). Cursor-paginated with an opaque next_cursor; default per_page=50, max 200. If the response has has_more=true, request the next page with the returned next_cursor — do not crank per_page.
AI agents call drive_browse_folder to retrieve information from TrekMail MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
