Invert a region. 取反当前ROI区域。 The new region contains all areas outside the original region. 新的区域包含原始区域之外的所有区域。 This operation creates the complement of the original region. 此操作创建原始区域的补集。 并输出一个新的复合ROI区域对象(ILCompoundRegion类型)的描述JSON。 其中ILCompoundRegion类型继承于ILRegion类型
AI agents use il_region_invert 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 |
|---|---|---|---|
regionClassObjDescriptionJson | string | — | 原始的Roi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。LpvClassName 表示要调用的Region接口名称，根据不同的区域类型 |
Parameters from the server's own tool schema.
The tool creates and returns a new region object that represents the inverse of an input region. This is data modification (Write) rather than Read because it generates new derived data structures. It is not Execute because it doesn't run arbitrary code or trigger external side effects—it performs a deterministic geometric operation.
From the tool's definition Tool description states it 'Invert a region' and 'creates the complement of the original region,' outputting 'a new composite ROI region object.' This modifies/creates new region data structures within the image processing context.
Attacks that exploit this kind of access
Invert a region. 取反当前ROI区域。 The new region contains all areas outside the original region. 新的区域包含原始区域之外的所有区域。 This operation creates the complement of the original region. 此操作创建原始区域的补集。 并输出一个新的复合ROI区域对象(ILCompoundRegion类型)的描述JSON。 其中ILCompoundRegion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_region_invert accepts 1 parameter: regionClassObjDescriptionJson. 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_region_invert: 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_region_invert 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_region_invert 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_region_invert. 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_region_invert 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.
