Security Findings (33)

  • HighAS-002

    ⚠️Excessive Permissions ×3

    tool declares network permission

    youtube_search

    tool declares exec permission

    youtube_create_playlistyoutube_update_playlist

    tool declares fs permission

    youtube_update_commentyoutube_delete_commentyoutube_create_playlistyoutube_update_playlistyoutube_delete_playlistyoutube_remove_playlist_item

  • LowAS-002

    ⚠️Excessive Permissions

    youtube_search:input schema exposes 13 properties (threshold: 10)

  • LowAS-011

    ℹ️Missing Rate-Limit / Timeout ×3
