What fillet_polyline does on Pypi:best Cad
AI agents use fillet_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 fillet_polyline is rated Medium
The fillet_polyline tool performs a geometric modification (rounding corner points) on a polyline, which is a reversible alteration of drawing data. This constitutes a Write operation—it creates or modifies data without permanently destroying it or executing arbitrary code.
From the tool's definition Tool description indicates the operation modifies polyline geometry by rounding all corners ("对整个多段线的所有角点进行圆角"). This is a modification operation on CAD drawing entities.
Attacks that exploit this kind of access
The rule that runs fillet_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 fillet_polyline, this is the rule to start with:
fillet_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 fillet_polyline call is checked against it from then on.
Questions about fillet_polyline
对整个多段线的所有角点进行圆角。实用接口。. 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 fillet_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.
fillet_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 fillet_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 fillet_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.
fillet_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.
