概览

AI 生成的概览

TranscriptFetch 让助手获取 YouTube、TikTok 和 Instagram 的视频转录文本、搜索视频并列出频道与播放列表，缺少字幕时自动进行 AI 转录。

可以做什么
  • 获取 YouTube、TikTok、Instagram 视频或直链媒体地址的转录文本，可选 markdown、分块或纯文本输出
  • 在 YouTube、TikTok 或 Instagram 上搜索视频，可按上传日期、时长、字幕筛选并排序
  • 按关键词查找频道和播放列表
  • 列出频道的视频、Shorts、直播、播放列表或播客，以及播放列表中的视频
  • 查询该 API 密钥剩余的额度
适用场景
适合让助手阅读、总结或引用 YouTube、TikTok、Instagram 的视频内容，或调研某个频道、播放列表，而无需手动复制转录文本。
运行要求
需要 TranscriptFetch 账号，并通过 TRANSCRIPTFETCH_API_KEY 提供 API 密钥。可使用托管远程端点（OAuth 或 API 密钥），或使用需 Node 18+ 的本地 npm 包（通过 npx 运行）。可选 TRANSCRIPTFETCH_BASE_URL 覆盖 API 主机。
安装前请注意
API 密钥是可计费的凭据，不要放入共享配置。用量按额度计费（每月 50 个免费额度），字幕获取和视频列表各 1 个额度，AI 转录按每开始 5 分钟音频 1 个额度计费且仅在交付时扣费。请求会把视频链接和搜索词发送给 TranscriptFetch 的 API。

交给智能体安装

把这段提示词粘贴到 Claude Code、Codex、Cursor 等智能体，或 SourceWeft 对话中。智能体会读取该服务器的安装指南，先向你展示发布者、端点和登录方式，经你同意后再把它添加到你的客户端。密钥不会写进任何命令。

阅读 https://sourceweft.com/mcp/com.transcriptfetch%2Fyoutube-transcripts/install.md，并按其中说明把这个 MCP 服务器接入我的客户端。修改任何配置之前，先告诉我它的发布者、端点和登录方式，等我确认。不要把 API 密钥写进命令或我会提交的文件；问我密钥应从哪里获取。

README

[TranscriptFetch]

TranscriptFetch MCP Server

A Model Context Protocol server that gives any MCP client (Claude Desktop, Cursor, and others) access to the TranscriptFetch API: a production transcript API for YouTube, TikTok and Instagram, with AI transcription when captions are missing. Fetch transcripts, search videos, list channels and playlists, and check your credit balance.

Get an API key

  1. Create a free account at transcriptfetch.com. No card needed.
  2. Open Dashboard, then API keys and create a key. It starts with tf_live_.
  3. Put it in TRANSCRIPTFETCH_API_KEY in the client configuration below.

Every account gets 50 free credits a month. Failures are free: a fetch that returns no transcript is never charged.

Runs locally over stdio and calls the TranscriptFetch API with your key. Prefer a hosted, remote server? Point your client at https://transcriptfetch.com/mcp instead (OAuth or API key). The hosted server waits inline for short-form AI transcription, so no polling is needed there.

Tools

ToolWhat it does
get_transcriptTranscript for a video: YouTube, TikTok, Instagram, or a direct media URL. When a video has no captions but has speech, the audio is transcribed automatically; ai_fallback: true goes straight to the audio. Optional markdown (timestamped, linked paragraphs), chunks (about 500 tokens each, for a vector store) and timestamps: false for text only
search_videosSearch YouTube (default), TikTok or Instagram. On YouTube, filter by upload_date, duration and captions, and sort by views
search_channelsFind YouTube channels (default) or playlists by keyword
list_channel_videosA YouTube channel's videos, Shorts or live streams (tab), sorted newest, popular or oldest, or searched with query; also a TikTok or Instagram profile
list_channel_playlistsA YouTube channel's playlists, or its podcasts
list_playlist_videosA YouTube or TikTok playlist's videos
get_creditsRemaining credit balance for the key. Never billed

These are the same seven tools, with the same inputs, as the hosted server at https://transcriptfetch.com/mcp: npm run sync-tools regenerates them from its public card.

Pricing is per successful result: a caption fetch or a video list costs 1 credit, and AI transcription of the audio costs 1 credit per started 5 minutes of audio, charged only on delivery. Failed, blocked and empty results are never charged, which matters on short-form video where many clips have no speech at all.

Install

No install needed. Run it on demand with npx:

bash
TRANSCRIPTFETCH_API_KEY=tf_live_... npx -y transcriptfetch-mcp

Or install globally:

bash
npm install -g transcriptfetch-mcp

Requires Node 18+.

Run from source

bash
git clone https://github.com/TranscriptFetch/mcp-servercd mcp-server && npm install && npm run build

Then point your client at the built entrypoint with "command": "node" and "args": ["/absolute/path/to/mcp-server/dist/index.js"].

Client configuration

Claude Desktop

Add this to claude_desktop_config.json (Settings then Developer then Edit Config):

json
{  "mcpServers": {    "transcriptfetch": {      "command": "npx",      "args": ["-y", "transcriptfetch-mcp"],      "env": { "TRANSCRIPTFETCH_API_KEY": "tf_live_..." }    }  }}

Cursor

Add the same block under mcpServers in your Cursor MCP settings.

Restart the client, and the five tools appear.

Example

Once connected, ask your assistant naturally:

Get the transcript for https://youtu.be/aircAruvnKk and summarize the key points.

Search YouTube for "how transformers work" and list the top 5 videos.

List the latest videos from @lexfridman and pull the transcript of the newest one.

How many TranscriptFetch credits do I have left?

The assistant picks the matching tool and works from the returned transcript or video list.

Configuration

Docker

The server speaks MCP over stdio, so there is no port to expose. -i is required: without an attached stdin the transport closes immediately and the container looks like it crashed.

bash
docker build -t transcriptfetch-mcp .docker run --rm -i -e TRANSCRIPTFETCH_API_KEY=tf_live_... transcriptfetch-mcp
