概览

AI 生成的概览

一个本地 MCP 服务器，用于获取 YouTube 视频字幕和元数据，并为助手准备可供总结的字幕内容。

可以做什么
以文本、JSON、SRT、WebVTT 或美化格式获取视频字幕，可选时间戳和元数据块，并列出视频可用的字幕语言。获取视频元数据，如标题、频道、上传日期、时长、观看数、标签和章节。列出公开播放列表中的视频，支持排序和结果数量限制。搜索 YouTube 视频，支持排序、上传时间和时长筛选，返回干净的排序列表。返回字幕并附带按标签分段的总结提示，便于人工审阅。
适用场景
适合让助手在不观看视频的情况下阅读、引用或总结 YouTube 内容，或为研究、内容工作收集视频、播放列表信息和搜索结果。
运行要求
以 Python 包（youtube-summarize）通过 uvx 在本地以 stdio 运行；需要 Python 3.13+ 和 uv 包管理器。需要访问 YouTube 的网络；未声明账号、API 密钥或环境变量。
安装前请注意
它会代你获取公开的 YouTube 数据，请求会发往 YouTube，可能受速率限制或被拦截。总结输出是供助手处理的材料，使用结果前请先审阅提示和字幕。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Youtube Summarize，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

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
