Get the pattern template mask. 获取模板蒙版。 The mask is used to exclude some not-care pixels during training. 蒙版用于在训练过程中排除一些不关心的像素。 It will be an empty image, if the template has no mask. 若当前模板没有蒙版，则返回一个空的图像。 返回结构是一个序列化的json，其中： ResultImg属性是模板蒙版图像的图片URL地址
AI agents call pat_match_get_pat_mask 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 is a read-only operation that queries and returns existing pattern mask data. It has no side effects, does not modify state, and poses minimal security risk even if misused by an agent—at worst, it would expose the mask image URL associated with a pattern template.
From the tool's definition Tool name 'pat_match_get_pat_mask' and description indicate it retrieves ('Get') a pattern template mask, returning a serialized JSON with an image URL. No modifications, deletions, or external operations are performed.

Get the pattern template mask. 获取模板蒙版。 The mask is used to exclude some not-care pixels during training. 蒙版用于在训练过程中排除一些不关心的像素。 It will be an empty image, if the template has no mask. 若当前模板没有蒙版，则返回一个空的图像。 返回结构是一个序列化的json，其中： ResultImg属性是模板蒙版图像的图片URL地址. 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_mask 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_mask: 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_mask 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_mask 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_mask. 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_mask 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.
