WHAT IT DOES

What image_pad does on farshid-mcp-imageProcessing

WHY IT NEEDS A POLICY

Why image_pad needs a policy

This tool modifies image data by adding borders or padding, which is a reversible transformation (the original image can be recovered or the operation undone). It does not delete, execute arbitrary code, move money, or trigger external systems—it simply transforms pixel data. This falls squarely into the Write category (creates or modifies data reversibly).

From the tool's definition Tool name 'image_pad' and description 'Add borders/padding around an image' indicate modification of image data by adding padding/borders, which creates a new or modified version of the image without destroying original data.
