Parameters from the server's own tool schema.
This tool modifies image data by applying a color space transformation formula (Gray = 0.114⋅B + 0.587⋅G + 0.299⋅R). While the original input image remains unchanged, the tool creates/outputs new image data in a different format. This is a reversible transformation (can convert back from grayscale), so it falls under Write rather than Destructive.
From the tool's definition Tool performs image conversion/transformation: 'Convert a BGR color image to grayscale' and 'The output image will be a grayscale image'. The description explicitly states it converts and outputs a transformed image.

Convert a BGR color image to grayscale 将 BGR 彩色图像转换为灰度图 - Convert a BGR color image to grayscale using the formula: Gray = 0.114⋅B + 0.587⋅G + 0.299⋅R - The input image must be a BGR color image - The output image will be a grayscale image of the same size as the input - 使用公式 Gray = 0.114⋅B + 0.587⋅G + 0.299⋅R 将 BGR 彩色图像转换为灰度图 - 输入图像必须是 BGR 彩色图像 - 输出图像将是灰度图像，尺寸与输入的彩色图像一致 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. 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_bgr_to_gray accepts 1 parameter: imageUrl. 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_bgr_to_gray: 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_bgr_to_gray 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_bgr_to_gray 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_bgr_to_gray. 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_bgr_to_gray 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.
