WHAT IT DOES

What export_dataset does on MCP DS Toolkit Server

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

WHY IT NEEDS A POLICY

Why export_dataset needs a policy

The tool writes/exports data to a file, which is a reversible modification action. It does not execute arbitrary code, delete data, or move money. While it persists data to storage, the action is reversible (the exported file can be deleted or overwritten).

From the tool's definition Tool name is 'export_dataset' and description states 'Export dataset to file'. This creates or writes data to a file system.
