What polyline_get_point_at_param does on Pypi:best Cad
AI agents call polyline_get_point_at_param to retrieve information from Pypi:best Cad without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why polyline_get_point_at_param is rated Low
This tool queries geometric properties of an existing polyline object—specifically retrieving the 3D point coordinates at a given parameter value along the polyline. It is a read-only query operation with no side effects on the drawing data or external systems. The low severity reflects minimal risk if misused by an AI agent, as it cannot alter state or cause harm beyond potentially extracting coordinate information.
From the tool's definition Tool name 'polyline_get_point_at_param' and description '获取多段线上指定参数处的3D坐标' (Get 3D coordinates at specified parameter on polyline) indicate data retrieval only. No modification, deletion, or external execution occurs.
Attacks that exploit this kind of access
The rule that runs polyline_get_point_at_param 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_get_point_at_param, this is the rule to start with:
polyline_get_point_at_param is read-only, so it stays allowed. 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 polyline_get_point_at_param call is checked against it from then on.
Questions about polyline_get_point_at_param
获取多段线上指定参数处的3D坐标。. It is categorised as a Read tool in the Pypi:best Cad MCP Server, which means it retrieves data without modifying state.
Register the Pypi:best Cad MCP server in PolicyLayer and add a rule for polyline_get_point_at_param: 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.
polyline_get_point_at_param is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the polyline_get_point_at_param 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 polyline_get_point_at_param. 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.
polyline_get_point_at_param 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.
