AI agents use il_region_xor 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.

Parameters from the server's own tool schema.
The tool creates and returns a new modified data structure (a region object) based on input regions. This is a reversible transformation that modifies image processing state (regions of interest) without permanently destroying data or executing arbitrary external operations. It fits the Write category as it creates a new derived data object.
From the tool's definition Tool description states it performs XOR operation on two regions and outputs 'a new composite ROI region object' (ILCompoundRegion type). This creates/modifies a new region object that represents the result of the XOR operation.
Attacks that exploit this kind of access
XOR two regions. 将当前ROI区域与输入的区域进行异或操作。 The new region contains parts that are exclusively in one region but not both. 新的区域仅包含属于当前区域但不属于输入区域或属于输入区域但不属于当前区域的部分。 If an empty region is XORed with any other region, an empty region is returned. 一个空区域与任何其他区域进行异或操作，获得一个空区域对象。 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_xor accepts 2 parameters: regionClassObjDescriptionJson, otherRegionClassObjDescriptionJson. 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_xor: 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_xor 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_xor 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_xor. 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_xor 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.
