Confirm the stored credentials work and report which channel they control.

Run this first when something is misbehaving. Quota cost: 1 unit.

Upload a video file to the authorized channel.

Quota cost: ~1600 units - about six uploads on the default daily allowance.

privacy_status is one of private/unlisted/public. Set publish_at (ISO 8601, e.g. 2026-09-10T15:00:00Z) to schedule a release; YouTube requires a scheduled video to be private until its moment arrives, so publish_at forces privacy_status to private.

made_for_kids is a legal declaration under COPPA, not a preference - set it to match what the content actually is.

Common category_id values: 22 People & Blogs, 27 Education, 28 Science & Technology, 24 Entertainment, 20 Gaming, 10 Music.

Change the metadata on an existing video. Only the fields you pass change.

Quota cost: ~51 units (1 to read the current state, 50 to write).

The underlying API replaces the whole snippet on write, so this reads the video first and merges - passing only title will not blank the description the way a raw API call would.

Schedule an existing private video to go public at a given time.

Quota cost: ~51 units. publish_at is ISO 8601, e.g. 2026-09-10T15:00:00Z; a bare timestamp is read as UTC. The video must stay private until then, which this sets for you.

Set a custom thumbnail. Quota cost: ~50 units.

Needs a verified channel with custom thumbnails enabled. JPEG or PNG, under 2MB, 1280x720 recommended.

List recent uploads on the authorized channel, newest first.

Quota cost: ~3 units. Use this to find the video_id the other tools need.

Channel-wide performance over a date range (YYYY-MM-DD).

Pass dimensions="day" for a time series, or "video" for a per-video breakdown of the period. Figures lag real time by roughly two to three days.
