Find the pixel of minimum value in the input image, report the value and pixel's position. If there's more than one pixel with the same value, report the left-top one. 查找输入图像中的最小灰度值像素，输出该灰度值和像素的位置。 若存在多个像素拥有同一灰度值，输出最左上的像素。 Returns a JSON string with the following fields: Value: The minimum value ...
AI agents call image_stats_min to retrieve information from Leaper Vision Toolkit without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
imageUrl | string | — | 图片的url地址，通过这个地址获取到输入图像 |
regionJson | string | — | 指定的Roi区域。如果用户没有指定区域，请直接传入 "null"。 如果用户指定区域，传入一个序列化的JSON字符串，属性包括：LpvClassName(调用工具函数的名称) 和 InputParameterFile(调用工具函数需要传入的参数文件名称)。这两个属性的值可以从前处理的MCP工具的返回值中获取。LpvCl |
Parameters from the server's own tool schema.
This tool purely analyzes an image and returns statistical information (minimum pixel value and its coordinates). It performs read-only computation with no side effects, data modification, or external operations.
From the tool's definition Find the pixel of minimum value in the input image, report the value and pixel's position
Attacks that exploit this kind of access
Find the pixel of minimum value in the input image, report the value and pixel's position. If there's more than one pixel with the same value, report the left-top one. 查找输入图像中的最小灰度值像素，输出该灰度值和像素的位置。 若存在多个像素拥有同一灰度值，输出最左上的像素。 Returns a JSON string with the following fields: Value: The minimum value PosX: The x-coordinate of the pixel's position with minimum value PosY: The y-coordinate of the pixel's position with minimum value 返回结构是一个序列化的JSON字符串，包含以下字段： Value: 最小灰度值 PosX: 最小灰度值所在像素的x坐标 PosY: 最小灰度值所在像素的y坐标. It is categorised as a Read tool in the Leaper Vision Toolkit MCP Server, which means it retrieves data without modifying state.
image_stats_min accepts 2 parameters: imageUrl, regionJson. 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 image_stats_min: 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.
image_stats_min is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the image_stats_min 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 image_stats_min. 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.
image_stats_min 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.
