tubedata

tubedata is a small local bridge to the hosted HasData YouTube MCP server, which returns YouTube data as JSON. Ask it for a search query and it returns the results page split into videos, channels, Shorts, shelves and ads; give it one video ID and it fetches that video's full details or its timed transcript; give it a channel ID or handle and it fetches that channel's page, tab by tab.

The bridge keeps no YouTube data of its own. It serves the upstream server's tool list locally, exactly as captured from the live endpoint, and forwards each tool call upstream, returning the result untouched. The captured surface is read-only public YouTube data: there is no upload, comment-posting, messaging, or payment tool in it.

Tools

• hasdata_youtube_search_getYoutubeSearchResults — search YouTube. Required: q. Optional filters include gl, hl, deviceType, sp, sortBy, date, videoType, length, filters__, and paginationToken. Returns video, channel and Shorts results, shelves, ads, and the total-results count.

• hasdata_youtube_video_getYoutubeVideo — fetch one video by its 11-character ID. Required: v. Optional: gl, hl, deviceType. Returns title, views and likes, duration, channel, description, caption tracks, music matches, and related rails.

• hasdata_youtube_channel_getYoutubeChannel — fetch one channel by ID (UC...) or handle (@name). Required: channelId. Optional: tab, gl, hl, deviceType, paginationToken. Returns channel identity, subscriber count, and the requested tab's items.

• hasdata_youtube_transcript_getYoutubeTranscript — fetch a video's timed transcript. Required: v. Optional: languageCode, type (asr for the auto-generated track). Returns transcript segments plus every available track on the video.

Configuration

• HASDATA_YOUTUBE_MCP_URL (optional) — override the upstream endpoint. Defaults to https://mcp.hasdata.com/mcp?apis=youtube. (The override hook is this rebuild's own labelled reconstruction.)

• HASDATA_API_KEY (optional) — when set, every upstream request carries an x-api-key: <key> header, for the caller's own HasData API key. When it is not set, no key header is sent. (The header name and the env name are pinned by the original's registry record; forwarding the key from this env var is a labelled reconstruction — the original surface was captured keyless.)

Forwarding mechanics

On the first tool call the client opens a streamable HTTP session with the upstream: a JSON-RPC initialize request (protocolVersion 2025-03-26, clientInfo name tubedata), then a notifications/initialized notification, then the tools/call request carrying the caller's arguments unchanged. When the upstream answers initialize with an Mcp-Session-Id header, that value rides on every later request of the session, which is reused for the life of the process. Replies may arrive as plain JSON or as server-sent events; both are read.

Successful upstream results pass through verbatim, including any isError flag the upstream sets. Failures — a JSON-RPC error, a non-2xx status, an unreadable response, or a request that cannot be completed — come back as an isError result whose text starts with tubedata error: (this rendering is this rebuild's own labelled reconstruction).

CLI

Each tool is also a subcommand taking one JSON argument string:

npx @reneturcios/tubedata hasdata_youtube_search_getYoutubeSearchResults '{"q":"lofi beats"}'
npx @reneturcios/tubedata hasdata_youtube_video_getYoutubeVideo '{"v":"dQw4w9WgXcQ"}'
npx @reneturcios/tubedata hasdata_youtube_channel_getYoutubeChannel '{"channelId":"@PewDiePie"}'
npx @reneturcios/tubedata hasdata_youtube_transcript_getYoutubeTranscript '{"v":"dQw4w9WgXcQ","languageCode":"en"}'
npx @reneturcios/tubedata --version

Exit codes: 0 on success, 1 on an isError result, 2 on a usage error.

MCP server

npx -y @reneturcios/tubedata mcp

MCP client config:

{
  "mcpServers": {
    "tubedata": {
      "command": "npx",
      "args": ["-y", "@reneturcios/tubedata", "mcp"]
    }
  }
}

Docker

docker run -i ghcr.io/cloudcorprecords/tubedata
docker run --rm ghcr.io/cloudcorprecords/tubedata --version

The container's default command is mcp, so the first form is a stdio MCP server; any other arguments reach the CLI normally.

Development

npm install
npm run build
npm test
npm run dev

The test suite runs entirely against a stubbed JSON-RPC upstream — no live network calls.
