概覽

AI 產生的概覽

一個本機 MCP 伺服器，用來取得 YouTube 影片字幕與中繼資料，並為助理準備可供摘要的字幕內容。

可以做什麼
以文字、JSON、SRT、WebVTT 或美化格式取得影片字幕，可選擇時間戳與中繼資料區塊，並列出影片可用的字幕語言。取得影片中繼資料，例如標題、頻道、上傳日期、長度、觀看數、標籤與章節。列出公開播放清單中的影片，支援排序與結果數量上限。搜尋 YouTube 影片，支援排序、上傳時間與長度篩選，回傳乾淨的排序清單。回傳字幕並附上依標籤分段的摘要提示，方便人工審閱。
適用情境
適合讓助理在不觀看影片的情況下閱讀、引用或摘要 YouTube 內容，或為研究、內容工作蒐集影片、播放清單資訊與搜尋結果。
執行需求
以 Python 套件（youtube-summarize）透過 uvx 在本機以 stdio 執行；需要 Python 3.13+ 與 uv 套件管理工具。需要連線至 YouTube 的網路；未宣告帳號、API 金鑰或環境變數。
安裝前請注意
它會代你取得公開的 YouTube 資料，請求會送往 YouTube，可能受速率限制或被阻擋。摘要輸出是供助理處理的素材，使用結果前請先審閱提示與字幕。

README

youtube-summarize

MCP server that fetches YouTube video transcripts and optionally summarizes them.

[Demo — summarizing a YouTube video in Claude]

Features

  • Fetch transcripts in multiple formats (text, JSON, SRT, WebVTT, pretty-print)
  • Video metadata — title, description, channel, upload date, duration, views, chapters (via yt-dlp)
  • Optional timestamps in plain-text transcripts
  • Summarize videos — returns transcript with the prompt clearly broken out for human review before the LLM acts on it
  • List playlist videos — fast enumeration of any public playlist with optional sorting
  • Search videos — clean ranked results with sort and filter options, without the ads, Shorts shelves, and personalized recommendations of the YouTube website
  • List available languages for any video's transcripts
  • Flexible URL parsing — accepts full YouTube URLs (youtube.com/watch?v=, youtu.be/, youtube.com/embed/, youtube.com/shorts/) or bare video IDs
  • Multi-language support — request transcripts in specific languages with fallback priority

Tools

get_transcript

Fetch a YouTube video's transcript. By default the response is prefixed with a [METADATA] block (title, channel, published, duration, views, description); pass include_metadata=false for transcript-only output.

ParameterTypeDefaultDescription
urlstringrequiredYouTube video URL or video ID
languagesstring[]["en"]Preferred languages in priority order
formatstring"text"Output format: text, json, pretty, webvtt, srt
preserve_formattingbooleanfalseKeep HTML formatting tags in the transcript
include_timestampsbooleanfalseWhen true with format="text", prefix each line with [HH:MM:SS]. Ignored for other formats (they already include timestamps).
include_metadatabooleantruePrepend a [METADATA] block before the transcript. Pass false for transcript-only output.

summarize_transcript

Fetch a transcript and return it with summarization instructions. The response is structured into clearly-labeled sections ([INSTRUCTIONS], [PROMPT_SOURCE], [VIDEO], [METADATA], [TRANSCRIPT]) so a human can review the prompt before letting the LLM act on it.

ParameterTypeDefaultDescription
urlstringrequiredYouTube video URL or video ID
promptstring(default prompt)Custom summarization instructions
languagesstring[]["en"]Preferred languages in priority order
include_timestampsbooleanfalsePrefix each transcript line with [HH:MM:SS].
include_metadatabooleantrueInclude a [VIDEO] block with title, channel, published, duration, views, and description.

get_video_metadata

Fetch metadata (title, description, channel, upload date, duration, views, tags, chapters, etc.) for a YouTube video. Backed by yt-dlp.

ParameterTypeDefaultDescription
urlstringrequiredYouTube video URL or video ID

list_playlist_videos

List the videos in a YouTube playlist (title, ID, channel, duration, views, URL). Per-video metadata is intentionally lean so the call stays fast even for large playlists; call get_video_metadata with a specific video ID for full detail.

ParameterTypeDefaultDescription
urlstringrequiredYouTube playlist URL (with ?list=...) or bare playlist ID
limitinteger500Maximum videos to return
sort_bystring"index"One of: index (playlist order), title, duration, views. upload_date is not supported.
orderstring"asc"asc or desc

search_videos

Search YouTube for videos and return a clean ranked list (title, ID, channel, duration, views, URL) — only actual videos, with no ads, recommendation shelves, or personalization. Relevance ordering still comes from YouTube's backend. Pair with get_transcript or summarize_transcript on a result's ID or URL.

ParameterTypeDefaultDescription
querystringrequiredSearch terms
limitinteger10Maximum results to return
sort_bystring"relevance"One of: relevance, date (newest first), views, rating
uploadedstring"any"Filter by upload time: any, hour, today, week, month, year
durationstring"any"Filter by length: any, short (<4 min), medium (4–20 min), long (>20 min)

list_transcripts

List available transcript languages for a video.

ParameterTypeDefaultDescription
urlstringrequiredYouTube video URL or video ID
