WHAT IT DOES

What rollback_undo_group does on Pypi:best Cad

AI agents use rollback_undo_group to create or update resources in Pypi:best Cad, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pypi:best Cad environment.

RISK

Why rollback_undo_group is rated Medium

This tool modifies drawing state by undoing/rolling back changes, making it a Write operation rather than Read (it changes data) or Destructive (the changes can be re-done via redo). The severity is medium because while it reverses modifications, those changes are typically recoverable through redo functionality, and the blast radius is limited to the current drawing's undo buffer.

From the tool's definition Tool performs 'rollback' operation on undo groups, which modifies the state of the CAD drawing by reversing recent changes. Description states it affects 'the current AutoCAD undo group'.

RECOMMENDED RULE

The rule that runs rollback_undo_group safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pypi:best Cad, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For rollback_undo_group, this is the rule to start with:

rollback_undo_group Rate-limited

rollback_undo_group 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.
