Create a rectangle region object. 创建一个矩形ROI区域对象。 Rectangular region is a simple rectangular area with the given top-left corner (x, y) and size (width, height). 矩形区域是一个简单的矩形区域，由给定的左上角位置 (x, y) 和尺寸 (width, height) 定义。 This region is axis-aligned with the image coordinate system. 该区域与图像坐标系对齐。 并返回生成...
AI agents use il_rect_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 |
|---|---|---|---|
Width | number | — | 矩形区域的宽度 (double类型) |
Height | number | — | 矩形区域的高度 (double类型) |
TopLeftX | number | — | 矩形区域左上角顶点的 x 坐标，即左边界 (double类型) |
TopLeftY | number | — | 矩形区域左上角顶点的 y 坐标，即上边界 (double类型) |
Parameters from the server's own tool schema.
This tool creates a new region data structure that can be used for image processing operations. It does not retrieve existing data (Read), execute arbitrary code (Execute), delete anything (Destructive), nor involve financial operations (Financial). It is a reversible creation of a geometric region object that would be used as input to other image processing tools.
From the tool's definition Tool creates a rectangle region object with specified coordinates and dimensions. The description explicitly states 'Create a rectangle region object' and 'returns the generated ILRectRegion type description JSON', indicating it generates and stores a data…

Create a rectangle region object. 创建一个矩形ROI区域对象。 Rectangular region is a simple rectangular area with the given top-left corner (x, y) and size (width, height). 矩形区域是一个简单的矩形区域，由给定的左上角位置 (x, y) 和尺寸 (width, height) 定义。 This region is axis-aligned with the image coordinate system. 该区域与图像坐标系对齐。 并返回生成后的ILRectRegion类型的描述JSON。 其中ILRectRegion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_rect_region accepts 4 parameters: Width, Height, TopLeftX, TopLeftY. 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_rect_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_rect_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_rect_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_rect_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_rect_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.
