Create a circle region object. 创建一个圆形ROI区域对象。 Circle region is a circular area defined by a center point and radius. 圆形区域是由中心点和半径定义的圆形区域。 This region covers the area inside the circle boundary. 该区域覆盖圆形边界内的区域。 并返回生成后的ILCircleRegion类型的描述JSON。 其中ILCircleRegion类型继承于ILRegion类型
AI agents use il_circle_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 |
|---|---|---|---|
r | number | — | 圆形区域的半径 (double类型) |
cenx | number | — | 圆形区域的 x 坐标 (double类型) |
ceny | number | — | 圆形区域的 y 坐标 (double类型) |
Parameters from the server's own tool schema.
This tool creates a new region data structure (circle region object) in memory, which is a reversible write operation. It does not retrieve existing data (Read), execute arbitrary code (Execute), delete data (Destructive), or involve financial transactions (Financial).
From the tool's definition Tool description states 'Create a circle region object' and 'returns the generated ILCircleRegion type description JSON'. The verb 'Create' indicates data object creation; the tool generates and returns a structured region object.
Attacks that exploit this kind of access
Create a circle region object. 创建一个圆形ROI区域对象。 Circle region is a circular area defined by a center point and radius. 圆形区域是由中心点和半径定义的圆形区域。 This region covers the area inside the circle boundary. 该区域覆盖圆形边界内的区域。 并返回生成后的ILCircleRegion类型的描述JSON。 其中ILCircleRegion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_circle_region accepts 3 parameters: r, 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_circle_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_circle_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_circle_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_circle_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_circle_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.
