What add_arc_dimension does on Pypi:best Cad
AI agents use add_arc_dimension 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.
Why add_arc_dimension is rated Medium
This tool creates new dimension annotations in an AutoCAD drawing, which modifies the drawing by adding geometric annotations. This is a reversible modification (dimensions can be deleted), making it a Write operation rather than Destructive.
From the tool's definition Tool name 'add_arc_dimension' and description '添加弧长标注(标注圆弧的弧长)' indicate adding/creating arc length dimension annotations to a CAD drawing.
Attacks that exploit this kind of access
The rule that runs add_arc_dimension 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 add_arc_dimension, this is the rule to start with:
add_arc_dimension 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Pypi:best Cad, apply this rule, and every add_arc_dimension call is checked against it from then on.
