WHAT IT DOES

What image_resize does on farshid-mcp-imageProcessing

AI agents use image_resize to create or update resources in farshid-mcp-imageProcessing — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your farshid-mcp-imageProcessing environment.

WHY IT NEEDS A POLICY

Why image_resize needs a policy

Resizing an image modifies the image data in a reversible way (the operation can be undone by resizing again). This is a write operation rather than read (it changes state), execute (no arbitrary code/commands), destructive (fully reversible), or financial.

From the tool's definition Tool name 'image_resize' and description indicate it modifies image dimensions. This creates or transforms image data, which is a reversible write operation. No deletion, code execution, or financial impact is present.
