Security checks across malware telemetry and agentic risk

Overview

This is a simple Douyin video downloader that performs expected network fetching and local file writing, with minor disclosure gaps but no evidence of malicious behavior.

Install this only if you intend to download Douyin videos. Expect it to contact Douyin-related hosts and save an MP4 locally; paste only links or share text you trust, and choose a safe output filename or folder so you do not overwrite an important file.

Medium

Category: MCP Least Privilege
Confidence: 88% confidence
Finding: The skill invokes a downloader script that requires outbound network access to douyin.com/iesdouyin.com, but the skill metadata does not declare any corresponding permission or capability boundary. This creates a transparency and governance gap: reviewers or runtime policy systems may treat the skill as lower risk than it actually is, and users may unknowingly trigger external requests and content retrieval.
