WHAT IT DOES

What denoise does on farshid-mcp-imageProcessing

AI agents use denoise 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 denoise needs a policy

Denoising transforms/modifies an image by reducing noise, which is a data modification operation. It is reversible in the sense that the original file can be retained, but the output is a new/modified image. No code execution, deletion, or financial action is involved. Severity is low as misuse would only result in an undesired image transformation.

From the tool's definition Non-local means denoising for color images — modifies image data by applying a denoising filter

denoise Rate-limited
