WHAT IT DOES

What stretch_entities does on Pypi:best Cad

AI agents use stretch_entities 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 stretch_entities is rated Medium

This tool modifies CAD drawing geometry by stretching/moving vertices and endpoints, which is a reversible geometric transformation. It creates a side effect in the drawing (altered entity positions) but does not delete data or execute arbitrary code. The modification is reversible through undo operations typical in CAD systems, making it Write rather than Destructive.

From the tool's definition Tool name 'stretch_entities' and description indicating it moves/displaces selected vertices and endpoints within a window of selected entities (拉伸选择窗口内实体, 移动被选中的顶点/端点).

Attacks that exploit this kind of access

RECOMMENDED RULE

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

stretch_entities Rate-limited

stretch_entities 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.
