AI agents use il_annulus_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 |
|---|---|---|---|
cenx | number | — | 圆环区域中心的 x 坐标 (double类型) |
ceny | number | — | 圆环区域中心的 y 坐标 (double类型) |
rInner | number | — | 圆环区域的内半径 (double类型) |
rOuter | number | — | 圆环区域的外半径 (double类型) |
Parameters from the server's own tool schema.
The tool generates an in-memory or session-scoped region definition object for image processing workflows. It is a constructive operation that produces a data structure without modifying underlying images, deleting data, executing external code, or causing financial transactions. This fits the Write category as a reversible creation of structured data used within the image processing pipeline.
From the tool's definition Tool creates and returns a region object ('Create an annulus region object', 'returns generated ILAnnulusRegion type description JSON'). This is a reversible data structure creation operation with no side effects on persisted data or external systems.
Attacks that exploit this kind of access
Create an annulus region object. 创建一个圆环ROI区域对象。 Annulus region is a ring-shaped area defined by an inner and outer circle with the same center. 圆环区域是由共享同一中心的内圆和外圆定义的环形区域。 The region covers the area between the inner and outer circles. 该区域覆盖内圆和外圆之间的区域。 并返回生成后的ILAnnulusRegion类型的描述JSON。 其中ILAnnulusRegion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_annulus_region accepts 4 parameters: cenx, ceny, rInner, rOuter. 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_annulus_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_annulus_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_annulus_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_annulus_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_annulus_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.
