WHAT IT DOES

What drawing_undo does on AutoCAD MCP Pro

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

RISK

Why drawing_undo is rated Medium

Undo reverses prior changes to drawings. Reversible but affects document state, warranting Write classification.

From the tool's definition uninformative description; undo suggests reversible modification

RECOMMENDED RULE

The rule that runs drawing_undo safely

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

drawing_undo Rate-limited

drawing_undo 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.
