WHAT IT DOES

What extend_entity does on Pypi:best Cad

AI agents use extend_entity 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 extend_entity is rated Medium

The tool modifies existing CAD entities by extending them geometrically, which is a Write operation—it creates a reversible change to drawing data. It is not Read (it changes state), not Execute (it doesn't run arbitrary code), not Destructive (the change can be undone via undo/redo in AutoCAD), and not Financial.

From the tool's definition Tool name 'extend_entity' and description '延伸实体到指定边界' (extend entity to specified boundary) indicates modification of CAD drawing geometry. This is a reversible modification operation within AutoCAD drawings.

RECOMMENDED RULE

The rule that runs extend_entity 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 extend_entity, this is the rule to start with:

extend_entity Rate-limited

extend_entity 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.
