Video Downloader

Security checks across malware telemetry and agentic risk

Overview

This skill is a straightforward yt-dlp video downloader with disclosed local command use, network access to user-provided video sites, and optional local preference memory.

Install only if you are comfortable running yt-dlp locally and sending the video URL to the relevant video host. Use it only for videos you have rights to download, choose an output folder deliberately, and decline or delete ~/video-downloader/ memory/log files if you do not want download preferences or history retained.

MCP Least Privilege
Confidence
83% confidence
Finding
The skill explicitly instructs the agent to execute local shell-capable tooling (`python3`, `yt-dlp`) but does not declare permissions for that capability. This creates a transparency and policy-enforcement gap: a host system may fail to prompt appropriately, apply least-privilege controls, or audit execution as expected, increasing the risk of unsafe command execution on user-supplied URLs and paths.

Missing User Warnings

Low
Confidence
89% confidence
Finding
The skill instructs the agent to store user preferences in a local memory file without explicitly informing the user that data will be written to disk or what data will be retained. This creates a privacy and consent issue: users may not realize their download habits, preferred formats, or paths are being persisted locally, which can be sensitive on shared systems or managed environments.
