AI agents use image_convert_depth16_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 |
fromNthBit | integer | — | 指定提取的开始索引，取值范围为 -7 ~ 15 |
Parameters from the server's own tool schema.
This tool modifies image data by converting bit depth and extracting specific bit ranges, producing a new image artifact. This is a reversible transformation (the original image remains unchanged) that creates/generates new data rather than deleting or executing arbitrary operations. It fits the Write category as it produces modified image data.
From the tool's definition Tool description states it 'Convert a 16bit image to 8bit depth, extracting the continues 8 bits from the specified index' and returns 'ResultImg: 输出结果图像URL地址' (output result image URL). This creates a new transformed image as output.

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_convert_depth16_to8 accepts 2 parameters: imageUrl, fromNthBit. 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_depth16_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_depth16_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_depth16_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_depth16_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_depth16_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.
