WHAT IT DOES

What add_region does on Pypi:best Cad

AI agents use add_region 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_region is rated Medium

This tool creates new region objects in AutoCAD by converting closed curves, which modifies the drawing state reversibly. It is a Write operation because it creates new design elements. Severity is medium because misuse could result in unwanted geometry added to drawings, but the action is reversible (regions can be deleted or modified).

From the tool's definition Tool name 'add_region' and description '将闭合曲线转换为面域对象' (convert closed curves to region objects) indicate creation/modification of CAD drawing objects. This is a drawing manipulation operation that creates new geometric objects within the design.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

add_region Rate-limited

add_region 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.

Questions about add_region

What does the add_region tool do? +

将闭合曲线转换为面域对象。. It is categorised as a Write tool in the Pypi:best Cad MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on add_region? +

Can I rate-limit add_region? +

Yes. Add a rate_limit block to the add_region rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block add_region completely? +
