Get the center of the pattern template. 获取当前配置的模板中心。 The template center indicates the report position of the matching result. 匹配结果将基于配置方式输出不同的中心点坐标。 For example, if the template center is moved to the left-top corner of the template image, we'll then always report the same left-top corner as the...
AI agents call pat_match_get_pat_center 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 |
|---|---|---|---|
matchClassObjDescriptionJson | string | — | 模板匹配的功能对象用于训练模板匹配的功能。如果用户没有指定模板匹配的功能对象，请创建一个模板匹配的功能对象后传入。 如果用户指定模板匹配的功能对象，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)。 |
Parameters from the server's own tool schema.
This tool retrieves configuration state (pattern center coordinates) from an image processing system. It performs no modifications, deletions, or external operations—it simply queries and returns data about the current template configuration. This is a standard Read operation typical of state inspection APIs.
From the tool's definition Tool name 'pat_match_get_pat_center' and description indicate retrieval of pattern template center coordinates (patX, patY, patAngle).
Attacks that exploit this kind of access
Get the center of the pattern template. 获取当前配置的模板中心。 The template center indicates the report position of the matching result. 匹配结果将基于配置方式输出不同的中心点坐标。 For example, if the template center is moved to the left-top corner of the template image, we'll then always report the same left-top corner as the matching result. 如若设置匹配图像的左上角点作为中心，所有的匹配结果将总是输出相同的左上角位置作为中心。 返回结构是一个序列化的JSON字符串，属性包括： patX 表示返回模板中心的 x 坐标,double类型。 patY 表示返回模板中心的 y 坐标,double类型。 patAngle 返回模板的 0° 角度 ,double类型。. It is categorised as a Read tool in the Leaper Vision Toolkit MCP Server, which means it retrieves data without modifying state.
pat_match_get_pat_center accepts 1 parameter: matchClassObjDescriptionJson. 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 pat_match_get_pat_center: 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.
pat_match_get_pat_center 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 pat_match_get_pat_center 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 pat_match_get_pat_center. 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.
pat_match_get_pat_center 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.
