Create a polygon region object. 创建一个多边形ROI区域对象。 Polygon region is defined by a set of vertices that form a closed polygon. 多边形区域由一组顶点定义，形成一个闭合多边形。 The region covers the area inside the polygon boundary. 该区域覆盖多边形边界内的区域。 并返回生成后的ILPolyRegion类型的描述JSON。 其中ILPolyRegion类型继承于ILRegion类型
AI agents use il_poly_region to create or update resources in Leaper Vision Toolkit — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Leaper Vision Toolkit environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
xs | array | — | 多边形区域顶点 x 坐标数组 (Array<double>类型) |
ys | array | — | 多边形区域顶点 y 坐标数组 (Array<double>类型) |
Parameters from the server's own tool schema.
This tool creates and instantiates a new region object with specified vertices. While it does not modify external systems or perform destructive operations, it is a generative/constructive action that creates a new data object. It falls under Write category (creates data structure) rather than Read (which would merely retrieve existing data).
From the tool's definition Tool creates a polygon region object (ILPolyRegion) and returns a JSON description of the generated object.
Attacks that exploit this kind of access
Create a polygon region object. 创建一个多边形ROI区域对象。 Polygon region is defined by a set of vertices that form a closed polygon. 多边形区域由一组顶点定义，形成一个闭合多边形。 The region covers the area inside the polygon boundary. 该区域覆盖多边形边界内的区域。 并返回生成后的ILPolyRegion类型的描述JSON。 其中ILPolyRegion类型继承于ILRegion类型. It is categorised as a Write tool in the Leaper Vision Toolkit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
il_poly_region accepts 2 parameters: xs, ys. The full parameter table on this page comes from the server's own tool schema.
Register the Leaper Vision Toolkit MCP server in PolicyLayer and add a rule for il_poly_region: 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 Leaper Vision Toolkit. Nothing to install.
il_poly_region 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 il_poly_region 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 il_poly_region. 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.
il_poly_region is provided by the Leaper Vision Toolkit MCP server (leaper-mcp/leaper-mcp-proxy). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
