Returns a video_id. Local file paths are not accepted; upload files outside the MCP server and pass a reachable video_url. The…\n  - `list_videos` (read-only): List all videos in your account, or filter to a specific group by passing group_id. Shows upload status and which features have been indexed for each video.…\n  - `get_video` (read-only): Get detailed information about a video including upload status, metadata (duration, resolution, fps), and per-feature indexing status. Use this to check if…\n  - `update_video`: Update a video's display name, title, description, or move it to a different group. At least one field must be provided. To remove a video from its group, pass…\n  - `delete_video`: Permanently delete a video and all its indexed data (transcript, captions, embeddings, etc.). This cannot be undone.\n  - `create_group`: Create a new video group. Groups organize videos into collections. Returns the new group's ID and name.\n  - `list_groups` (read-only): List all video groups. Use list_videos with a group_id to see videos in a specific group.\n  - `delete_group`: Delete a video group.
