AI agents use il_ellipse_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 |
|---|---|---|---|
a | number | — | 椭圆区域的旋转角度 (主轴方向) (double类型) |
h | number | — | 椭圆区域的高度 (短轴长度) (double类型) |
w | number | — | 椭圆区域的宽度 (主轴长度) (double类型) |
cenx | number | — | 椭圆区域中心点的 x 坐标 (double类型) |
ceny | number | — | 椭圆区域中心点的 y 坐标 (double类型) |
Parameters from the server's own tool schema.
This tool creates a new data structure (an ellipse region object) in memory or in the image processing context. It is a generative operation that modifies the state of the application by instantiating a new object, which classifies it as Write rather than Read. It has no destructive, financial, or execute (command) aspects.
From the tool's definition Tool creates an ellipse region object with parameters (center point, major/minor axes, rotation angle) and returns a JSON description of the generated ILEllipseRegion type.
Attacks that exploit this kind of access
Create an ellipse region object. 创建一个椭圆ROI区域对象。 Ellipse region is an elliptical area defined by a center point, major and minor axes, and rotation angle. 椭圆区域是由中心点、长短轴和旋转角度定义的椭圆区域。 The region covers the area inside the ellipse boundary. 该区域覆盖椭圆边界内的区域。 并返回生成后的ILEllipseRegion类型的描述JSON。 其中ILEllipseRegion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_ellipse_region accepts 5 parameters: a, h, w, cenx, ceny. 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_ellipse_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_ellipse_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_ellipse_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_ellipse_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_ellipse_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.
