• Find Best Expertfind_best_expert_for_topicRead-only

• Founder statusfounder_statusRead-only

  The user's status in the TubExperto founders programme (by invitation): founder profile, free plan and until when, partner commission and whether it is active, referral link, and progress on the "while you collaborate" commitment (days with activity and feedback against the minimums, deadline). Free, read-only; says so if the user is not a founder.

• Due reviewsget_due_reviewsRead-only

  Spaced-repetition (SM-2) quiz questions due now, plus a summary (total cards, due, streak, per-expert breakdown). Read-only: grades and reschedules nothing. Free.

• Search Videossearch_videosRead-only

  Search videos on a topic across THREE scopes: the user's experts (free), the shared catalog (free) and/or YouTube globally (not yet indexed); default `auto` blends all three. Returns a numbered list with a `searchId` that `import_videos` can reference. Pass `channelId` to search INSIDE one YouTube channel, indexed or not (each result says whether it is imported and what importing costs); with `channelId` and no `topic` it lists the channel's latest uploads. Free.

• Import Videosimport_videosSpends credits

  Import videos into the user's library, by `{searchId, indices[]}` (list from `search_videos`) or `{videoIds[]}`. Videos already in the shared catalog are instant and free; brand-new ones cost 1 credit each and are queued for processing. Max 10 per call. The channel must already be an expert: `subscribe_to_channel` first if needed.

• Get Import Statusget_import_statusRead-only

  Poll imports started with `import_videos` or `subscribe_to_channel`, by `jobIds[]` or `videoIds[]`. Returns stage progress and per-job `capabilities`: `queryable` (query_expert works), `summarizable` (get_video_summary works). Poll until `allReady: true` to query, `allSummarizable: true` before summaries. Free.

• Search Channelssearch_channelsRead-only

  Search YouTube channels on a topic, blending the TubExperto catalog (subscribing is free) and YouTube globally. Returns a numbered list plus a `searchId` for `subscribe_to_channel`. Free.

• Subscribe to Channelsubscribe_to_channelAdds data

  Add a YouTube channel to the library as an expert, by `{channelId}` (UC… or @handle), `{channelUrl}` or `{searchId, index}`. Subscribing costs 0 credits, but a BRAND-NEW channel takes one expert slot of the plan; importing videos later costs 1 credit per new video. The response returns `cost` and `expertSlots`: tell the user before importing. Channels other users imported get instant access; new ones are created with the N most recent videos preselected.

• List Channel Uploadslist_channel_uploadsRead-only

  List the full chronological uploads of ONE YouTube channel by `{channelId}`, `{channelUrl}` or `{expertId}`. Returns a numbered list plus a reusable `searchId` for `import_videos {searchId, indices}`. For "the whole channel" rather than a topic search. Max 200. Free.

• Index a video on demandlazy_index_videoSpends credits

  Transcript/info of ONE YouTube video by URL or ID even if its channel is NOT indexed. Two steps: call WITHOUT confirm to learn the cost (1 credit for a brand-new video; free for Shorts), which charges nothing; call with confirm:true to get the RAW transcript at once and start full channel indexing in the background. For videos already in the library use get_transcript.

• Research a Topicstart_topic_researchSpends credits

  Start an open YouTube investigation on a topic when the user does not know which channel to ask. It plans queries, discovers candidate videos, READS their transcripts and returns a curated learning path (sections in teaching order, each video with why, level and which minutes to watch). Asynchronous: returns a `researchId` and the path is ready in 90-300 s; poll get_topic_research every 15-30 s. Costs by depth: quick 2, standard 4, deep 8 credits, refunded in full if it fails or is cancelled. Free plans: only `quick`, twice per rolling week.

• Get Topic Researchget_topic_researchRead-only

  Check a research started with start_topic_research. While running: `status`, pipeline `stage`, `progress`, `estimatedSecondsRemaining` (poll every 15-30 s). When completed: the curated path, a ready-to-present Markdown rendering, the `conversationId` of its thread and `nextSteps` (import cost, followable channels). Then answer follow-ups with continue_topic_research (free) instead of researching again.

• Continue Researchcontinue_topic_researchAdds data

  Ask a follow-up about a FINISHED topic research, answered from the transcripts and pages it read, with `[videoId@mm:ss]` citations to the exact second; it remembers earlier turns. FREE: no credits, cheaper than a second research. If the answer needs more of a video than was sampled, it returns `needsImport` with the import cost: say the cost and ask before import_topic_research_videos. The turn is saved in the research conversation (`conversationId`), visible on the website.

• List Topic Researcheslist_topic_researchRead-only

  List the user's topic researches, newest first: topic, goal, depth, status, path title when finished, and the `conversationId` of its thread (null = no follow-up asked yet). Free.

• Cancel Topic Researchcancel_topic_researchDeletes or revokes

  Cancel a running topic research (credits refunded in full) or delete a finished one (removes it and its path for good; videos already imported stay in the library). The response says which happened. Free.

• Import Research Videosimport_topic_research_videosSpends credits

  Import the videos of a finished research into the library so query_knowledge_base can use them. `videoIds` picks some; omit it for the whole path. Costs 1 credit per brand-new video, 0 for those already in the shared catalog: ALWAYS state the cost (in get_topic_research nextSteps) and get the user's agreement first. Channels not yet experts are subscribed automatically (one expert slot each); a channel without a slot sends its videos to `skipped[]`, the rest still import.

• Follow Research Channelsfollow_topic_research_channelsAdds data

  Follow channels from a topic research as experts (only channels of that research). Free, but each new channel takes one expert slot; without a slot it returns in `skipped[]`. Catalog channels are followed at once (`followed[]`); unindexed ones are queued (`queued[]` with an `importJobId`; poll `get_import_status`). Following adds the channel, importing adds the path's videos. Ask the user before calling.

• Research Quizgenerate_topic_research_quizSpends credits

  Costs 1 credit. Quiz on a topic research to check what the user retained; nothing needs importing (built from what the research read and any stored transcripts). `videoId` quizzes one video of the path; omit for the whole route. Runs in the background: the first call answers `queued`, ready in 1-2 minutes; call again to collect it (free, never charged twice). Refunded if generation fails.

• Export Research Reportexport_topic_researchRead-only

  Export the report of a finished research (overview, numbered path with link and reason per video, answer or competitor analysis, channels, gaps). `md` (default) returns Markdown inline; `pdf` and `docx` return a download link. Free.

• List Topic Watcheslist_topic_watchesRead-only

  List the user's topic watches (each scans new uploads of the channels they follow and alerts on a topic match): id, topic, whether active, delivery (`instant` or `daily`), last scan. Free.

• Create Topic Watchcreate_topic_watchAdds data

  Create a topic watch: every 2 hours, new uploads of the channels the user follows are scored against `query` and relevant ones become alerts with a 2-3 line reason and the exact minute. Write `query` as a rich description (3-300 characters: subject, words a video would use, competitors or names). `digestFrequency`: `instant` (default; urgent alerts by email at once, rest in the daily digest) or `daily`. Max 10 per user. Free (cost capped by TubExperto, no credits). Ask the user before creating one.

• Topic Watch Alertsget_topic_watch_alertsRead-only

  Alerts of ALL the user's topic watches since a moment (default last 24 h), newest first: video and channel, watch topic, score, `urgent` (worth interrupting now; the rest belongs in a daily digest), 2-3 line reason, matching minute and `url` pointing at it. Also the month spend against the monthly cap. Free.

• Ask My TubExperto Conversationsask_tubexperto_conversationsRead-only

  Searches the conversations stored in TubExperto (not Claude's or any assistant's own chat history or memory): chats the user had in TubExperto with their channels, videos, panels and researches, on the website, app or these tools. Answers with numbered citations to each conversation, e.g. "what did I ask TubExperto about X?", "did I already research Z?". For what a CHANNEL says about a topic use query_knowledge_base. Hybrid search (meaning + exact words). Free; the free plan gets 5 a day.

• Export to Notes (Obsidian, Notion, Markdown)export_conversationAdds data

  Export a conversation (or one answer) as a note: `markdown`, `obsidian` (YAML frontmatter, questions as callouts) or `notion` (Notion-ready Markdown). Citations become links to the YouTube video at that second, plus a sources list per answer. Returned inline; with `destination: "notion"` it is created as a page in the user's connected Notion (else the Markdown is returned). Without `conversationId` it exports the latest MCP conversation. Free.

• Publish a Public Linkshare_public_linkAdds data

  Publish a conversation, one answer or a video summary as a public read-only page (frozen copy) with a link anyone can open. NEVER call with `confirm: true` unless the user explicitly asked to publish: the first call (no `confirm`) publishes nothing and returns what would become public, so show it and ask. Author name hidden unless `showAuthor: true`; `noindex: true` keeps it out of search engines. Revocable with revoke_public_link. Free.

• My Public Linkslist_public_linksRead-only

  List the user's active public links with their URL, visits and shareId. Free.

• Revoke Public Linkrevoke_public_linkDeletes or revokes

  Revoke one of the user's public links: the page stops working immediately. Free.

• Search My LibrarysearchRead-only

  Search the videos in your TubExperto library by keywords in title or transcript. Returns JSON `results` (id, title, url); pass an id to `fetch`. Free.

• Read Video from My LibraryfetchRead-only

  Read a library video by the id `search` returned. Returns JSON id, title, text (transcript), url. A long transcript comes in parts: the footer of `text` says which `part` to ask for next. Free; each part counts against the same daily limit as `get_transcript`.
