显示 Excel 列.
AI agents call show_excel_cols to retrieve information from Office 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 displays Excel column information. It performs a query/read operation with no side effects, no data modification, and no execution of arbitrary code. The context of the Office MCP Server (which includes sibling tools for creating, editing, and adding content) further supports that this is a read-only display function. Read operations pose minimal security risk when misused by an AI agent.
