excel_anova · Office MCP Server MCP: Risk & Policy

WHAT IT DOES

What excel_anova does on Office MCP Server

AI agents invoke excel_anova to trigger actions in Office MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why excel_anova needs a policy

This tool executes a statistical analysis (ANOVA) operation on Excel data, likely reading data and writing results back to a document. It spans Read and Write, but since it performs a computation/processing operation (running analysis and generating output), Execute is the most appropriate category. The description is minimal (translated: 'Excel variance analysis (ANOVA)'), which slightly lowers confidence.
