What draw_3d_polyline does on Pypi:best Cad
AI agents use draw_3d_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.
Why draw_3d_polyline is rated Medium
This tool creates (writes) a new 3D polyline geometry into the CAD drawing. It is a reversible creation operation (the object can be deleted afterward), placing it in the Write category. Misuse could corrupt a drawing but is not inherently destructive or irreversible.
From the tool's definition 绘制三维多段线(每个顶点可以有不同的Z坐标)— 'draw' / '绘制' indicates creation of a new 3D polyline entity in the CAD drawing
Attacks that exploit this kind of access
The rule that runs draw_3d_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_3d_polyline, this is the rule to start with:
draw_3d_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.
The button opens the PolicyLayer dashboard: create your workspace, connect Pypi:best Cad, apply this rule, and every draw_3d_polyline call is checked against it from then on.
Questions about draw_3d_polyline
绘制三维多段线(每个顶点可以有不同的Z坐标)。. 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.
Register the Pypi:best Cad MCP server in PolicyLayer and add a rule for draw_3d_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.
draw_3d_polyline is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the draw_3d_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.
Set action: deny in the PolicyLayer policy for draw_3d_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.
draw_3d_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.
