WHAT IT DOES

What add_shape does on Pypi:best Cad

AI agents use add_shape 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 add_shape is rated Medium

This tool adds shapes to a CAD drawing, which modifies the drawing content. It creates new objects (shapes from .shx files) but does not irreversibly delete data or execute arbitrary code—the operation is reversible through standard CAD undo mechanisms. The changes are localized to the drawing being edited.

From the tool's definition Tool description states 'insert predefined shape' (从 .shx 形状文件中插入预定义图形) and name 'add_shape' indicates creation/modification of drawing content. The action creates new geometric objects in the CAD drawing.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

add_shape Rate-limited

add_shape 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_shape call is checked against it from then on.
