WHAT IT DOES

What polyline_add_vertex does on Pypi:best Cad

AI agents use polyline_add_vertex 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 polyline_add_vertex is rated Medium

This tool creates/modifies CAD drawing data by adding vertices to existing polylines. This is a reversible modification (vertices can be deleted or adjusted), fitting the Write category. Severity is medium because misuse could corrupt or deface drawings, but the action is undoable and localized to polyline geometry rather than destructive deletion or financial impact.

From the tool's definition Tool name 'polyline_add_vertex' and description '向多段线在指定位置添加新顶点' (Add new vertex to polyline at specified position) indicate modification of CAD drawing geometry by adding vertices to polylines.

RECOMMENDED RULE

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

polyline_add_vertex Rate-limited

polyline_add_vertex 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.
