这个是将两个图像逐像素相减的工具。输出一个新图像，两个输入图像需尺寸相同、类型相同。 工具不需要通过其它工具设置参数，不需要传入ILImageOp的对象。 返回结构是一个序列化的json，其中： ResultImg属性是输出结果图像URL地址。 English: The two input images should have the same size and format. 中文: 两个输入图像需尺寸相同、类型相同。
AI agents use il_image_op_sub 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 |
|---|---|---|---|
imageUrl1 | string | — | 图片的url地址，通过这个地址获取到图片1 |
imageUrl2 | string | — | 图片的url地址，通过这个地址获取到图片2 |
Parameters from the server's own tool schema.
The tool creates a new derived image by processing two input images through subtraction. While it modifies/creates data, the operation is fully reversible (can be undone by re-adding the subtracted values or discarding the result), has no side effects beyond generating an output image, and poses minimal security risk.
From the tool's definition Tool performs pixel-by-pixel subtraction of two images and outputs a new image (ResultImg URL). The description states it creates output: '输出一个新图像' (outputs a new image) and returns a 'ResultImg属性是输出结果图像URL地址' (ResultImg property is output image URL address).

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_image_op_sub accepts 2 parameters: imageUrl1, imageUrl2. 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_image_op_sub: 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_image_op_sub 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_image_op_sub 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_image_op_sub. 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_image_op_sub 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.
