CodexSame directory, one install: ChatGPT and Codex share it. In a Codex task open Sources → Use plugins → Transcriptor; in the CLI, /plugins.

🧩 Any other MCP client

If your client is not in the list above, add the server with this configuration:

json
{  "mcpServers": {    "transcriptor": {      "url": "https://transcriptor.gateway.mcpal.io/mcp"    }  }}

If you want to run the server yourself, read Self-host. The tools are the same and you need no account.

🧰 What you can ask

Ask for thisTool
"Summarize this video for me"get_transcript
"Give me the subtitles as an SRT file"get_raw_subtitles
"Is there a German track for this video?"get_available_subtitles
"Who published this and how many views?"get_video_info
"Go to the part about pricing"get_video_chapters
"Show me the screen at 4:12"get_video_frame
"Get English transcripts for the first 5 videos in this playlist"get_playlist_transcripts
"Find recent videos about X"search_videos (YouTube)

Long transcripts come in parts. Each response gives a cursor for the next part, so no text is lost.

Full tool reference (input and structured response)

Each tool that takes a video accepts url. This is a link from a supported platform or a plain YouTube ID. Each tool returns content (text for the chat) and structuredContent (typed JSON for your code).

get_transcript

Clean plain text, without timestamps, HTML, or speaker names. Without lang, the tool returns the track in the video's original language. Most platforms other than YouTube do not say which language a video is in; when the tool cannot tell which track that is, it answers with the list of tracks, and you call it again with type and lang. The inputs are the same as for get_raw_subtitles.

Response: videoId, url (the video page, as the server resolved it), type, lang, text, is_truncated, total_length, start_offset, end_offset. When more text is available, the response also has next_cursor.

get_raw_subtitles

Raw SRT or VTT content, in parts.

Input:

  • type — official or auto. Without lang, the tool picks a track of this type
  • lang — a language code or track name, as get_available_subtitles lists it. Without it, the video's original language, as for get_transcript
  • response_limit — default 50000, minimum 1000, maximum 200000
  • next_cursor — the cursor of the previous response

Response: the fields of get_transcript, plus format (srt or vtt) and content.

get_available_subtitles

Response: official and auto. Each field is a sorted list of language codes. Use this tool first, then give type and lang to the tools above.

get_video_info

Extended metadata from yt-dlp:

  • identity — videoId, title, description, webpageUrl
  • author — uploader, uploaderId, channel, channelId, channelUrl
  • numbers — duration, uploadDate, viewCount, likeCount, commentCount
  • classification — tags, categories, liveStatus, isLive, wasLive, availability
  • images — thumbnail and thumbnails
get_video_chapters

Response: chapters. Each item has startTime, endTime, and title. When the video has no chapters, the list is empty.

get_video_frame

Input:

  • timecode — "MM:SS" or "HH:MM:SS.mmm"
  • seconds — an alternative to timecode. Give one of the two, not both
  • format — jpeg (default) or png
  • width — default 1280, maximum 1920, never larger than the source
  • quality — 2 to 31, for jpeg only

Response: an image block, plus url, timestampSeconds, timestamp, mimeType, sizeBytes, and width. This tool needs ffmpeg. The Docker image includes it.

get_playlist_transcripts

Input:

  • url — a playlist URL, or a watch URL with list=
  • type, lang, format — the same as get_raw_subtitles, except that lang is required: the original language is picked only for one video at a time
  • playlistItems — a yt-dlp -I value such as 1:5, 1,3,7, or -1
  • maxItems — the maximum number of videos

Response: results. Each item has videoId and text.

search_videos

Input:

  • query — the search text
  • limit — default 10, maximum 50
  • offset — the number of results to skip
  • uploadDateFilter — hour, today, week, month, or year
  • response_format — json (default) or markdown

Response: results. Each item has videoId, title, url, duration, uploader, viewCount, and thumbnail.

📺 Widgets

Four tools have an interactive interface: get_transcript, get_video_info, get_video_frame, and search_videos. Clients that support MCP Apps and the ChatGPT Apps SDK show this interface in the chat. Other clients get the same data as text and JSON.

[The search_videos widget: a carousel of result cards with thumbnails, durations, and view counts]

search_videos · "model context protocol MCP server production"

 [The get_video_frame widget: one captured frame with step controls and a timecode field]

get_video_frame · an architecture slide at 3:30

[The get_transcript widget: a video card above a searchable list of timed captions]

get_transcript · a 3-minute MCP explainer, official captions

 [The get_video_info widget: thumbnail, channel, views, likes, description, and a subtitle language picker]

get_video_info · channel, views, likes, and 169 caption languages

🌍 Platforms

YouTube · Twitter/X · Instagram · TikTok · Twitch · Vimeo · Facebook · Bilibili · VK · Dailymotion · Reddit

Each tool that takes a video accepts a link from these 11 platforms. The tool search_videos works with YouTube only, through yt-dlp ytsearch.

The server does not download video or audio files for you. It returns text, metadata, and single frames.

🐳 Self-host

The tools are the same as on the hosted endpoint. You need no account.

Run the server with Docker. The image serves Streamable HTTP on port 4200:

bash
docker run --rm -p 4200:4200 artsamsonov/transcriptor-mcp:latest

Then point your client at http://localhost:4200/mcp.

For stdio, give the image an explicit command:

bash
docker run --rm -i artsamsonov/transcriptor-mcp:latest npm run start:mcp
json
{  "mcpServers": {    "transcriptor": {      "command": "docker",      "args": ["run", "--rm", "-i", "artsamsonov/transcriptor-mcp:latest", "npm", "run", "start:mcp"]    }  }}

The server starts with no environment variables. Each variable below is optional.

VariableDefaultFunction
MCP_PORT and MCP_HOST4200 and 0.0.0.0The HTTP listener
COOKIES_FILE_PATH—A Netscape cookies file for videos that need an account. See cookies.example.txt
WHISPER_MODEoffSet local or api to transcribe the audio when a video has no subtitles. Then set WHISPER_BASE_URL or WHISPER_API_KEY. WHISPER_MAX_DURATION_SECONDS skips longer videos and live streams; a video whose length the platform does not report is measured with ffprobe after the audio download
CACHE_MODEoffSet redis and CACHE_REDIS_URL to cache subtitles and metadata
YT_DLP_MAX_CONCURRENCY4How many yt-dlp/ffmpeg processes may run at once. YT_DLP_MAX_QUEUE (8) is how many calls may wait; beyond that a call is refused at once with "server busy". A call peaks at ~40 MiB, so the cap bounds platform throttling and latency, not memory
SUBTITLES_RATE_LIMIT_HOLD_MS600000After a platform answers 429 to a subtitle download, the server stops asking that platform for subtitles for this long and answers rate_limited right away. Each repeat doubles the wait, up to an hour; a successful download clears it. Metadata is not held back
CANARY_INTERVAL_MS900000How often the HTTP server fetches one transcript to prove the path still works. 0 turns it off; CANARY_URL picks the video
YT_DLP_*—Timeouts, proxy, and JS runtimes. See .env.example

The same port serves GET /health and GET /metrics. The metrics are in Prometheus format and include the mcp_* counters.

Transport, REST API, and development

Transport. The server accepts POST /mcp only. GET and DELETE return 405. The server is stateless and sends no Mcp-Session-Id.

The Node process does not check bearer tokens. Put a reverse proxy or a gateway in front of it for authentication and TLS. The hosted endpoint works this way.

REST API. A second image gives the same extraction over plain HTTP:

bash
docker run --rm -p 3000:3000 artsamsonov/transcriptor-mcp-api:latest

The Swagger interface is at http://localhost:3000/docs. For a full stack with the API and the MCP server, read docker-compose.example.yml.

Development.

bash
npm cinpm run buildnpm run start:mcp        # stdionpm run start:mcp:http   # Streamable HTTP on port 4200npm test

You need Node.js 22 or later (20 still works, but it reached end of life in April 2026), and yt-dlp in your PATH. Frame capture needs ffmpeg, and WHISPER_MAX_DURATION_SECONDS needs ffprobe (both ship in the same package, and in the Docker image). Other scripts: lint, type-check, format, test:coverage, test:e2e:api, and test:e2e:mcp.

Releases. The maintainer cuts them. The steps are in .claude/skills/release/SKILL.md. The version comes from package.json at runtime, through src/version.ts. Pushing a v* tag makes CI build both images and publish the MCP Registry entry from server.json.

Layout. src/mcp.ts (stdio entry), src/mcp-http.ts (Streamable HTTP), src/mcp-core.ts (tools, prompts, widgets), src/youtube.ts (yt-dlp), src/whisper.ts, src/cache.ts, src/index.ts (REST API), load/ (k6), and src/e2e/ (Docker smoke tests).
