export_pbit_file · PBIFORGE MCP: Risk & Policy

WHAT IT DOES

What export_pbit_file does on PBIFORGE

AI agents use export_pbit_file 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_pbit_file needs a policy

This is a Write operation because it creates and stores a new file artifact on the local filesystem. While it involves persistence, it is reversible (the file can be deleted or overwritten), so it does not qualify as Destructive. The severity is medium because exporting files could potentially expose or duplicate sensitive dashboard configurations, though the impact depends on what data the .pbit contains.

From the tool's definition Tool description states 'save the .pbit locally' which indicates data creation and storage to a file system. The tool compiles a session state and persists it as a .pbit (Power BI Template) file.

export_pbit_file Rate-limited

export_pbit_file stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
