Excel 描述性统计分析.
AI agents call excel_descriptive_statistics 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.
Descriptive statistics tools calculate summary metrics (mean, median, std dev, etc.) from existing data. This is a read/analytical operation with no side effects. Confidence is slightly reduced because the description is minimal and in Chinese, leaving some ambiguity about whether it writes results back to the file.
From the tool's definition '描述性统计分析' means 'descriptive statistics analysis' — a read/compute operation that analyzes existing Excel data without modifying it.
