归一化输入图像到 8 位图 返回结构是一个序列化的JSON字符串，包含以下字段： ResultImg: 输出结果图像URL地址
AI agents use image_convert_normalize_to8 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 |
|---|---|---|---|
imageUrl | string | — | 图片的url地址，通过这个地址获取到输入图像 |
maxValue | number | — | 最大值，传入0表示使用图像最大值 |
minValue | number | — | 最小值，传入0表示使用图像最小值 |
Parameters from the server's own tool schema.
The tool creates a new processed image as output, which is a form of data creation/modification. It does not execute arbitrary code or delete data, making it Write rather than Execute or Destructive. However, the output is derived computation rather than direct persistent storage modification, and the scope is limited to image processing, keeping severity at medium rather than high.
From the tool's definition Tool name 'image_convert_normalize_to8' and description indicate it converts/normalizes an input image to 8-bit format and returns a processed image URL. This is image transformation that creates modified output data.

image_convert_normalize_to8 accepts 3 parameters: imageUrl, maxValue, minValue. 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_convert_normalize_to8: 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_convert_normalize_to8 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_convert_normalize_to8 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_convert_normalize_to8. 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_convert_normalize_to8 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.
