WHAT IT DOES

What draw_polyline does on Pypi:best Cad

AI agents use draw_polyline 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 draw_polyline is rated Medium

This tool creates new polyline objects in an AutoCAD drawing, which is a reversible modification operation. It does not execute arbitrary code, delete data, or move financial resources. The blast radius is medium because a malicious agent could create many objects to clutter/degrade drawings, but changes can be undone.

From the tool's definition Tool name 'draw_polyline' and description '绘制二维多段线(连续折线)' (draw 2D polyline/continuous broken line) directly indicate creation of new geometric entities in a CAD drawing.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

draw_polyline Rate-limited

draw_polyline 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.

FAQ

Questions about draw_polyline

What does the draw_polyline tool do? +

绘制二维多段线(连续折线)。. 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 draw_polyline? +

Register the Pypi:best Cad MCP server in PolicyLayer and add a rule for draw_polyline: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Pypi:best Cad. Nothing to install.

What risk level is draw_polyline? +

draw_polyline is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit draw_polyline? +

Yes. Add a rate_limit block to the draw_polyline 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 draw_polyline completely? +

Set action: deny in the PolicyLayer policy for draw_polyline. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides draw_polyline? +

draw_polyline is provided by the Pypi:best Cad MCP server (pypi:best-cad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
