Overview

This transcript skill does the requested job, but it also ships a YouTube/Google cookie file that appears to contain account session material.

Review before installing. Do not use this package as-is unless the bundled cookie file is removed and any cookie-based authentication is explicitly user-provided, documented, and limited to the requested video. The likely affected Google/YouTube session should be revoked or rotated.

Medium

• Category: MCP Least Privilege
• Confidence: 89% confidence
• Finding: The skill clearly performs outbound network access to YouTube transcript services and can write transcripts to local files, yet the manifest does not declare corresponding permissions. Undeclared capabilities undermine least-privilege review and make it harder for the host to enforce policy or obtain informed user/admin consent, even though the documented behavior appears aligned with the skill's stated purpose.
