AI agents use image_set_to_color 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 |
|---|---|---|---|
red | integer | — | 红色通道值，范围0-255 |
blue | integer | — | 蓝色通道值，范围0-255 |
green | integer | — | 绿色通道值，范围0-255 |
imageUrl | string | — | 当前图像的url地址，通过这个地址获取到输入图像 |
regionJson | string | — | 指定的Roi区域。如果用户没有指定区域，请直接传入 "null"。 如果用户指定区域，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。LpvCl |
Parameters from the server's own tool schema.
The tool creates or modifies image data by altering pixel color values in a specified region. This is a Write operation—the changes are intentional data modification but are reversible (the original image could be restored). The blast radius is medium because misuse could corrupt or deface images, but no data is permanently destroyed and the operation is not a financial or code execution risk.
From the tool's definition Tool modifies pixels in an image by 'setting' them to specified RGB values ('仅用于彩色图像' / 'for color images'). Returns 'ResultImg: 设置颜色后的图像结果' (image result after setting color). This is a reversible modification of image data, not destructive deletion.

将图像中给定区域内的像素设置为指定的 RGB 值。仅用于彩色图像。 蓝色通道值范围0-255，绿色通道值范围0-255，红色通道值范围0-255。 返回结构是一个序列化的JSON字符串，包含以下字段： ResultImg: 设置颜色后的图像结果 Set the pixels in the given region of the image to the specified RGB value. This function is only for color images. Blue channel value range 0-255, green channel value range 0-255, red channel value range 0-255. Returns a serialized JSON string containing the following fields: ResultImg: The image result after setting color. 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.
image_set_to_color accepts 5 parameters: red, blue, green, imageUrl, regionJson. 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 image_set_to_color: 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.
image_set_to_color 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 image_set_to_color 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 image_set_to_color. 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.
image_set_to_color 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.
