AI agents use il_annulus_sector_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 |
|---|---|---|---|
aEnd | number | — | 环状扇形区域的结束角度 (double类型) |
cenx | number | — | 环状扇形区域所在圆中心点的 x 坐标 (double类型) |
ceny | number | — | 环状扇形区域所在圆中心点的 y 坐标 (double类型) |
aStart | number | — | 环状扇形区域的起始角度 (double类型) |
rInner | number | — | 环状扇形区域的内侧半径 (double类型) |
rOuter | number | — | 环状扇形区域的外侧半径 (double类型) |
Parameters from the server's own tool schema.
This tool creates a new region object (an annulus sector ROI) in memory. It constructs/instantiates a data object, which is a reversible write-style operation. There are no destructive, financial, or execution side effects — it simply defines a geometric region and returns a JSON description of it. Severity is low as misuse has minimal blast radius.

Attacks that exploit this kind of access
Create an annulus sector region object. 创建一个环状扇形ROI区域对象。 Annulus sector region is a sector-shaped area within a ring, defined by start and end angles. 环状扇形区域是圆环内的扇形区域，由起始角度和结束角度定义。 The region covers the area between inner and outer circles within the specified angular range. 该区域覆盖指定角度范围内的内圆和外圆之间的区域。 并返回生成后的ILAnnulusSectorRegion类型的描述JSON。 其中ILAnnulusSectorRegion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_annulus_sector_region accepts 6 parameters: aEnd, cenx, ceny, aStart, rInner, rOuter. 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_annulus_sector_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_annulus_sector_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_annulus_sector_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_annulus_sector_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_annulus_sector_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.
