What draw_xline does on Pypi:best Cad
AI agents use draw_xline 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_xline is rated Medium
draw_xline creates and adds construction lines to an AutoCAD drawing, which modifies the drawing state reversibly. This is a Write operation—it adds new objects to the design but does not execute arbitrary commands, delete data, or move money.
From the tool's definition Tool name 'draw_xline' and description '绘制构造线(通过两点的双向无限长直线)' (translate: 'draw construction line (infinite straight line in both directions through two points)'). This creates new geometric entities in the CAD drawing.
Attacks that exploit this kind of access
The rule that runs draw_xline 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_xline, this is the rule to start with:
draw_xline 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_xline call is checked against it from then on.
Questions about draw_xline
绘制构造线(通过两点的双向无限长直线)。. 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.
Register the Pypi:best Cad MCP server in PolicyLayer and add a rule for draw_xline: 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_xline 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_xline 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_xline. 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_xline 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.
