WHAT IT DOES

What webcam_record does on farshid-mcp-imageProcessing

AI agents invoke webcam_record to trigger actions in farshid-mcp-imageProcessing. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why webcam_record needs a policy

This tool activates the webcam hardware and records video, which is an external operation with privacy implications. It captures real-world audio/video data and writes it to disk. The act of triggering webcam recording without user awareness is a significant privacy risk, classifying it as Execute with high severity due to potential for covert surveillance if misused by an AI agent.
