WHAT IT DOES

What color_convert does on farshid-mcp-imageProcessing

AI agents use color_convert 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 color_convert needs a policy

Color space conversion modifies image data (e.g., RGB to grayscale, HSV, etc.), making it a Write operation. It creates a new or modified version of the image. It is reversible (the original can be retained) and has no destructive, financial, or execution implications. Blast radius is low as it only affects image data passed to it.

From the tool's definition 'Convert color space' — transforms image data from one color representation to another, producing a modified output

color_convert Rate-limited

color_convert stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
