AI agents use il_mask_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 |
|---|---|---|---|
tlx | number | — | 蒙版区域的左上角点 x 坐标 (double类型) |
tly | number | — | 蒙版区域的左上角点 y 坐标 (double类型) |
maskImageUrl | string | — | 图片的url地址，通过这个地址获取到输入蒙版图像 |
Parameters from the server's own tool schema.
This tool creates a new mask region object based on a binary image mask input. It is a reversible Write operation—it generates a new data structure without deleting or executing arbitrary code. The mask region is a computational artifact for image processing, not an irreversible deletion or code execution.
From the tool's definition Tool name 'il_mask_region' with description stating 'Create a mask region object.' The verb 'Create' indicates data generation/creation. Returns 'ILMaskRegion type description JSON' which represents creating a new data structure.
Attacks that exploit this kind of access
Create a mask region object. 创建一个蒙版ROI区域对象。 Mask region is defined by a binary image mask, where white pixels represent the region area. 蒙版区域由二值图像蒙版定义，其中白色像素表示区域范围。 The mask image determines the shape and extent of the region. 蒙版图像决定区域的形状和范围。 并返回生成后的ILMaskRegion类型的描述JSON。 其中ILMaskRegion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_mask_region accepts 3 parameters: tlx, tly, maskImageUrl. 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_mask_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_mask_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_mask_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_mask_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_mask_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.
