WHAT IT DOES

What export_pbix does on PBIFORGE

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

WHY IT NEEDS A POLICY

Why export_pbix needs a policy

The tool creates and outputs a new file artifact (a Power BI .pbix file encoded as base64). This is a Write operation—it produces persistent output data that can be saved to disk or transmitted. It is not Destructive because it does not delete or irreversibly remove existing data.

From the tool's definition Tool description states 'Compile the current session into a .pbix file and return it as base64.' This generates and exports a file artifact (a compiled .pbix Power BI file) from the current session state.
