Show whether Google OAuth is configured, which YouTube channels are connected (and whether their sign-in is healthy), the default channel, today’s quota use, and known project limitations. Call this first in a new conversation.

Start Google sign-in to connect (or reconnect) a YouTube channel. Opens the browser on this computer and returns the sign-in link; the user picks the Google account and channel (brand accounts work). Waits up to wait_seconds for them to finish.

List the YouTube channels connected to this server.

Choose which connected channel is used when a tool call does not name one.

Remove a connected channel and revoke this app’s Google access to it. Needs the user’s confirmation.

Upload a video file from this computer (file_path) or a public URL to YouTube with a resumable, checkpointed upload that survives network drops and restarts. Optionally schedule it (publish_at), set a thumbnail, add it to playlists and attach captions in the same call. Runs in the background: returns a job_id right away (or the finished video if it completes within wait_seconds). Poll get_upload_status. Private uploads start immediately; public, unlisted and scheduled uploads need the user’s confirmation first. Tip: write metadata first (generate_metadata, then preview_metadata).

Status of an upload job (progress, errors, resulting video) and/or a video’s YouTube processing state (processing, failed, rejected), plus a check for the "locked to private" restriction. Can wait for changes.

Recent upload jobs from this computer, newest first, with progress and results.

Stop an upload job that has not finished. It can be resumed later with resume_upload.

Resume a stopped, failed or cancelled upload from the last byte YouTube confirmed (for example after a quota reset or reconnecting the channel). Network drops and quota resets are also retried automatically.

List videos on the channel, newest first (including private, unlisted and scheduled ones), with privacy, schedule, duration and view counts. Paginate with page_token.

Full details of one video: metadata, privacy and schedule, processing state, duration, captions flag and statistics.

Change a video’s title, description, tags, category, languages, audience and other settings. Only the fields you pass change. Optionally apply a template to the fields you pass (title format; footer and hashtags when you pass description; template tags when you pass tags). Changing visibility to public/unlisted or scheduling needs the user’s confirmation (or use set_visibility).

Change who can see a video: private, unlisted or public, or schedule it with publish_at. Anything other than private needs the user’s confirmation.

Permanently delete a video from YouTube. Cannot be undone. Always needs the user’s confirmation.

Upload a JPG or PNG (max 2 MB, ideally 1280x720) from this computer as the video’s thumbnail. The channel must be phone-verified.

Add or update the title and description shown to viewers in other languages, e.g. {"hi": {"title": "...", "description": "..."}}. Merged with existing translations. The video needs a default_language set (update_video).

YouTube video categories you can assign (id and name) for a region.

All playlists on the channel with id, title, privacy and video count.

Create a new playlist on the channel.

Add a video to a playlist by playlist id or exact title. Optionally at a position (0 = first).

Remove a video from a playlist (the video itself is not deleted).

Rename a playlist, change its description or privacy. Making it public or unlisted needs the user’s confirmation.

Delete a playlist (the videos in it are not deleted). Needs the user’s confirmation.

Move a video to a new position in a playlist (0 = first). Works for playlists sorted manually.

Videos in a playlist, in order.

Caption tracks on a video (language, name, auto-generated or uploaded, draft).

Add a captions track (.srt, .vtt or other YouTube-supported format) to a video, from a file on this computer or inline content.

Delete an uploaded caption track (see list_captions for ids). Needs the user’s confirmation.

Download a caption track of your own video as SRT (prefers uploaded tracks, falls back to auto-generated). Costs 250 quota units.

Transcribe a video file on this computer with any OpenAI-compatible speech-to-text API (needs ffmpeg and a configured key). Saves an .srt you can pass to upload_video or upload_captions, and returns a timestamped transcript for writing metadata and chapters.

Collect everything needed to write a strong title, description, chapters and tags: the transcript with timestamps (from text you pass, a .srt/.vtt/.txt file, an uploaded video’s captions, or by transcribing a local file), the chosen template and YouTube’s rules. You then write the metadata and check it with preview_metadata.

Show exactly what would be sent to YouTube (title, description, tags, playlists) after applying a template, and check it against YouTube’s limits and chapter rules. No API call, no quota.

Metadata templates (title format, description footer, default tags, hashtags, category, playlists, voice guidance) available for uploads.

Create or replace a metadata template, saved as JSON in the templates folder. Use {title} in title_format. extends inherits another template; tags and hashtags combine.

Delete a saved template file.

Estimated YouTube API quota used today (units and uploads) for this Google Cloud project, and when it resets (midnight Pacific Time).

The channel’s title, handle, description, keywords, country, default language, trailer, subscriber/view/video counts, banner and settings.

Change the channel description, keywords, country, default language or the trailer shown to non-subscribers. Only the fields you pass change. These are public, so the user confirms first. (The channel name and handle can only be changed in YouTube Studio.)

Upload a channel banner (JPG/PNG, 16:9, at least 2048x1152, ideally 2560x1440, max 6 MB). Public, so the user confirms first.

Set the subscribe watermark shown on all channel videos (square JPG/PNG, at least 150x150, max 1 MB), or remove it with remove: true.

Comment threads on one video, or across the whole channel (newest first). Filter by moderation state (published, held_for_review, likely_spam) or search text. Includes replies.

Post a public reply to a comment (comment_id = the top-level comment or thread id) or a new top-level comment on a video (video_id). Posts publicly as the channel, so the user confirms the exact text first.

Publish held comments, hold comments for review, or remove (reject) them; optionally ban the author from commenting on the channel. Removing or banning needs the user’s confirmation.

Delete a comment or reply that the channel itself wrote (other people’s comments are removed with moderate_comments). Needs the user’s confirmation.

YouTube Analytics for the channel or one video. Reports: overview (views, watch time, average view duration, subscribers gained/lost, likes, comments, shares), daily (trend by day), top_videos (best performers with titles), traffic_sources, search_terms (YouTube search queries), geography, devices, demographics (age/gender), retention (audience retention curve, needs video_id), subscribed_status, or custom (your own metrics/dimensions). Defaults to the last 28 days. Data lags about 2 days.
