"How to find or generate YouTube video transcripts" matching MCP tools:

• analyze_video_report

  switch

  Run the FULL Switch Vision analysis on a video, the same premium report the Video Analysis page produces: it watches AND listens in three forensic passes and returns a structured report with every category: overview (scores and takeaways), a second by second timeline, audio, visual craft, story and retention, speech transcript, ready to run recreation prompts, and metadata. Pass video_url (a public https video URL, YouTube included) OR one of your own Switch video ids. For an external file also pass duration_seconds (YouTube and your own videos are measured automatically) because the analysis is billed per second of the file, 3 tokens per second with a 30 second minimum. Re-running the same video and question returns the existing report without charging again. Optional question focuses the analysis. Returns a report_id right away; poll get_vision_report until status is succeeded (a few minutes). If it cannot finish, your tokens are returned automatically. For one quick question about a video use analyze_video instead; this tool is the full paid report.

• download_video

  TubePull

  Download a video or audio file from any supported platform: YouTube, TikTok, Instagram (public reels, feed video, photo posts, and carousels), SoundCloud, Vimeo, Dailymotion, Bandcamp, Twitter/X, Mixcloud, Twitch (clips and VODs), Streamable, Reddit, Kick (live streams, VODs, and clips). Output is MP4 (video, default) or MP3 / M4A (audio). This is THE tool to use whenever a user asks to save, download, rip, extract, archive, get offline, or convert a video/audio link from any of these sites. IMPORTANT: the `format` argument defaults to `mp4` (video). Only pass an audio format (mp3 / m4a / audio) when the user explicitly says audio, MP3, music, song, or "rip / extract the audio". Audio-only platforms (SoundCloud, Bandcamp, Mixcloud) always produce audio regardless of `format`. Use this tool when the user says things like: - "download this video" / "download this TikTok" / "save this SoundCloud track" - "save that as MP3" / "rip the audio" / "extract the audio" - "get the song from this SoundCloud link" / "save this Mixcloud set" - "convert this YouTube video to MP4" / "download in 1080p" - "save this lecture/podcast/talk for offline" - "archive this clip" / "grab a copy of this video" - any sentence containing a youtube.com, youtu.be, tiktok.com, reddit.com, v.redd.it, vimeo.com, dailymotion.com, twitter.com, x.com, soundcloud.com, bandcamp.com, mixcloud.com, twitch.tv, clips.twitch.tv, kick.com, or streamable.com URL plus a verb like download, save, rip, get, grab, fetch, pull, archive, convert, extract. Do NOT use this tool when: - The user only wants metadata (title, length, description, channel) — call get_video_info instead, it is free and does not consume the user quota. - The link is a playlist / set / album / channel URL — ask the user for a single track/video. - The link is from a platform not in the supported list above (e.g. Facebook, LinkedIn, Snapchat). Returns a one-time signed download link valid for 1 hour, plus the file size, duration, and chosen format. Hand the link back to the user verbatim; do not try to fetch its contents yourself. Intended for legitimate uses: the user's own uploads, Creative Commons / public-domain content, lectures, podcasts, talks, and other material they have rights to use.

• list_videos

  HelloBooks AI Agents MCP Server

  List HelloBooks product videos curated on the marketing site (homepage demo + feature walkthroughs) and the official @hellobooksai YouTube channel link. Each video returns title, description, category, watch URL, embed URL and thumbnail. Filter by category (demo / features / overview), featuredOnly, or free-text query. Use this when a user asks for a demo, walkthrough or video. Note: this is the curated set, not a live mirror of every channel upload — the response includes the channel URL for the full catalog.

• publish

  uplika

  Post to social channels. Channels open today: threads, youtube. Get accountIds from select_channels — do not guess which channel the person meant. Text limits differ per channel: Threads 500 characters, YouTube 5000 UTF-8 bytes. Over the limit nothing goes out to any channel, so shorten it before calling. Images and video both work on the channels that take them, and a carousel can mix them. YouTube is different: it takes exactly one video, no images, and it needs options.youtube.title. Its description is measured in UTF-8 bytes, so Korean and Japanese cost three per character. There are three ways to get a media id, pick by where the file is: media_from_url when it already has a public https address, media_upload_link when it is on the person's own device, media_presign plus media_complete when you can PUT the bytes yourself. Then pass the media ids here. This publishes immediately on every channel except YouTube, which can be scheduled with options.youtube.publishAt while privacyStatus is private. If the user asks to schedule anywhere else, tell them uplika cannot do that yet. A YouTube video published before Google finishes reviewing this app is locked to private viewing, so say that when you report a YouTube post as done. Returns while the post is still publishing. The permalink is null at that moment. Call get_post with the returned id to see the final status and link. Pass wait: true to hold the response until it is really out — then you can tell the person it is posted instead of guessing. For a long post use threadItems instead of publish-then-reply: we keep the order and wait for each piece to land before sending the next one.

• get_channel_transcripts

  YouTube Transcript Downloader

  Get transcripts for a YouTube channel's most recent videos (newest first) as timestamped markdown, one section per video. Use for research across a creator's recent output; for one known video use get_transcript. Read-only; requires an API key. Charges 1 credit per video that returns a transcript, including repeat calls; videos without captions are skipped free. A 10-video call typically costs up to 10 credits, so start with a small limit. Rate limit: 5 requests per 10 seconds.

• hgvs_convert

  workbench

  Parse an HGVS "c." variant description (by gene symbol, RefSeq NM_, or Ensembl ENST accession), convert it to genomic (g.) coordinates via a real, live-fetched Ensembl exon/CDS map (transcripts resolved through the bundled MANE RefSeq<->Ensembl crosswalk), apply 3'-rule normalization to any del/dup/ins, and predict the protein (p.) effect where that is safely computable. Refuses cleanly — rather than guessing — for circular/mitochondrial genomes, RNA-level or protein-level input, uncertain/mosaic syntax, splice-junction-adjacent or inversion protein effects, and non-MANE/non-Ensembl transcripts.

• create_style

  framesail

  Create a style. Two mutually exclusive paths: References (best): inputs=[{"input_type": "youtube" | "text", "value": "<url or description>"}] — YouTube videos are watched (a channel link or @handle resolves to that channel's newest usable upload) and text directions read; async analysis writes the style's art/narrative/director fields: await_jobs(style_id=...) before using the style. (Image/video FILE references require the multipart REST endpoint POST /styles.) Presets (instant, no analysis): presets={"art_style": id, "narrative_style": id, "director_style": id} — all three axes, ids from list_style_presets.

• check_account

  vivideo

  Get the account plan, premium status, and remaining credit balance. Use this to decide whether the user can generate a video (rendering needs a premium plan and enough credits). Returns plan, premium, credits, free_video_available, and links (upgrade / buy_credits). Cheap and safe to call often.

• update_youtube_video

  Hermoso

  Edit an existing video on the connected channel: title, description, tags, and/or privacy (unlisted | public | private). THIS IS HOW YOU FLIP AN UNLISTED UPLOAD PUBLIC — post_to_youtube defaults to UNLISTED, and without this there was no way to publish it afterwards. Making a video PUBLIC puts it on the channel where anyone can find it, so show the user exactly what will change and get an explicit yes before calling with privacy:"public". Fields you omit are left untouched. Needs a connected YouTube channel.

  Connector

• delete_youtube_video

  Hermoso

  PERMANENTLY delete a video from the connected YouTube channel. IRREVERSIBLE — YouTube has no trash and no undelete, and the video's views, comments and every link or embed pointing at it go with it. Call it WITHOUT confirm first: nothing is deleted, and it reports the video's REAL title, privacy, view count and comment count read back from YouTube. Show the user that, get an unambiguous yes, then call again with confirm:true — plus, once the video is public or has any views or comments, confirmTitle set to its exact title. confirmTitle exists because confirming that you meant to delete SOMETHING does not prove you aimed at the right video, and a wrong id must not be confirmable blind. If the user only wants it out of public view, use update_youtube_video(privacy:"private") instead — that is reversible and this is not. Get the videoId from list_youtube_videos. 0 credits. Needs a connected YouTube channel.

• resolve_post_url

  Viral Outliers

  Takes a public post URL (TikTok video/photo, Instagram post/reel, YouTube video/short) and resolves it to the tracked post: the entry point when your input is a link. found:true returns the postId for get_post, request_transcript, download_post_media and remix_post. found:false tells you whether the whole profile is untracked (call crawl_profile) or just this post. TikTok/Instagram short links (vm.tiktok.com, /share/) must be expanded to the canonical URL first. Cost: 1 credit per call.

• get_shared_transcript

  RiverScript

  Fetch the full text of a transcript that someone has shared publicly from RiverScript, given its share link. Use this when the user pastes a riverscript.com/share/... link, or asks about the contents of one, so you can answer questions about the recording, summarise it, pull quotes, or translate it. Works for transcripts and for translations of transcripts. Only returns transcripts whose owner made them public; private, expired, or deleted links return nothing.

• youfiliate_disconnect_youtube

  Youfiliate Smart Links

  Disconnect your YouTube account from Youfiliate. IMPORTANT: Always confirm with the user before executing this action. The `confirm` parameter must be set to true. This removes stored OAuth tokens. You will need to reconnect to use the auto-migration feature. Does NOT modify any YouTube data or video descriptions. Common errors: - Not connected: no YouTube account to disconnect. - confirm=False: you must set confirm=True after getting user confirmation.

• analyze_video

  switch

  Switch Vision — watch and understand a video (or image) like a human and answer a question about it: scenes, subjects, actions, on-screen text, pacing, mood and sentiment. Pass video_url (a public https video URL, including YouTube) OR one of your own Switch videos (a video/asset id from list_my_videos / list_my_assets / upload_media). Add an optional question to focus the analysis (e.g. "what is the tone and energy?", "list the cuts and what each shot shows"). Use this whenever the user gives you a reference video and wants its style, energy, structure or content understood — for example before making a new video that matches it.

• framefetch_extract

  framefetch

  Extract data from ONE public social-video URL (YouTube incl. Shorts, TikTok, Instagram Reels, Pinterest, Reddit): metadata/insights/transcript/frames/digest/comments/etc — see `fields`. When NOT to use: non-video pages, private/login-walled content, or bulk crawling (one URL per call). Returns one JSON object with only the requested fields + a `cost` block (micro-USD); shapes: https://framefetch.net/docs. Cost scales with what you request (frames/transcript cost more than metadata). No key? POST /v1/keys {email} -> instant key (~100 free calls); or x402 (USDC), no account. Example: {"url":"https://www.youtube.com/watch?v=...","fields":["metadata","transcript"]}.

• extract_clip

  Weftly

  Cut and assemble a clip from any prior video job (find_clips, summarize, or video transcribe). Operates on a parent job — possessing the parent `source_job_id` is the capability, no upload step. Pass one segment for a simple cut, or multiple non-contiguous segments to compose a single mp4 highlight reel — same flat $0.50 either way. Two-call flow: (1) call with `source_job_id` + `segments` (ordered array of `{start, end, label?}` in source seconds, total duration capped at 30 minutes) to receive {job_id, payment_challenge}; (2) pay via MPP and call with `job_id` + `payment_credential` to start processing. No upload step. Poll get_job_status(job_id) for completion; outputs are role `clip-video` (the assembled .mp4, frame-accurate boundaries with 15ms audio fades at segment joins; audio loudness-normalized to -14 LUFS / -1.5 dBTP for clean, consistent playback) and — when `include_transcript: true` (default) — roles `clip-srt` + `clip-words` (transcripts stitched and time-shifted to match the assembled video). Set `include_transcript: false` to skip transcript outputs. Payment: pay by credit card via the Stripe Checkout link (open the returned `payment_url` in any browser) or Tempo USDC via mppx; the challenge's WWW-Authenticate header and /.well-known/mpp.json are authoritative for which methods are offered. Source must still be in storage (72h TTL for find_clips parents, 24h elsewhere — check `expires_at` from get_job_status on the parent). Multiple extract_clip calls against one parent are independent paid jobs. Failed jobs auto-refund.

• decode_ad

  Heista

  Decode a specific video ad URL into its full structural formula — beat-by-beat breakdown, hook classification, behavioral psychology stack, creative format, runtime performance signals (active days on Meta Ad Library when available), and per-cut visual data. Takes one video URL plus an optional idempotency_key. Returns a job_id immediately; poll with get_decode every 15s until status is "completed" (typically 45-60s end-to-end). Use this when the user pastes an ad URL, names a specific competitor ad, asks "decode this" or "break down this ad" or "what makes this ad work", or wants sentence-level fidelity to one specific winner before writing a script with generate_adscript. Supports Facebook Ad Library, TikTok, Instagram Reels, YouTube Shorts, and direct .mp4 URLs. Costs 15 credits for videos ≤60s, 20 credits for 61-120s. Do NOT use to browse the corpus or find ads by category — use decoder_intelligence or adformula_intelligence (both free) for discovery. Do NOT use for image ads or static creative.
