WHAT IT DOES

What export_data_to_csv does on PowerBI MCP Server

AI agents use export_data_to_csv to create or update resources in PowerBI MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your PowerBI MCP Server environment.

WHY IT NEEDS A POLICY

Why export_data_to_csv needs a policy

This tool creates/generates a new data export file (CSV), which is a reversible write operation. While the CSV is created outside PowerBI, the underlying data in PowerBI remains unmodified. The severity is medium rather than low because unintended bulk data exports could expose sensitive organizational data, though the action itself is reversible (the CSV can be deleted).

From the tool's definition Tool name 'export_data_to_csv' and description 'Export data from a PowerBI table to CSV format' indicate creation of a new file artifact in CSV format.
