WHY IT NEEDS A POLICY

Why edit_image needs a policy

Based on the tool name 'edit_image' and the server's stated purpose of AI-powered image editing, this tool most likely modifies an existing image, which is a Write operation. Sibling tools like 'advanced_edit' confirm editing is a core capability. However, the empty description significantly lowers confidence — it could potentially be destructive (overwriting originals) or execute arbitrary transformations.

From the tool's definition Tool name 'edit_image' on a server described as providing 'image editing' capabilities; description is empty and uninformative.
