Summary
One tool, one URL, and a video becomes text.
It does a single thing and asks for nothing in return — no key, no install — which makes it the connector you leave switched on. The transcript arrives with title, duration and the available languages, so a summary or a quote can be produced immediately.
What it is
A hosted MCP server exposing one tool that returns the full text transcript of a YouTube video, backed by youtube-transcript.ai. The connector URL is https://youtube-transcript.ai/mcp.
What you get
- The complete transcript as plain text, with the video's title, duration and the list of caption tracks available
- Any URL form accepted — watch links, youtu.be, shorts, embed — or a bare 11-character video ID
- A caption track chosen by BCP-47 language code (en, zh-CN, es, ja and so on), or the default track if you say nothing
- A fetch pipeline with proxy fallback, so videos that block ordinary scrapers still return text
Requirements
No account, no token and no quota wall — add the URL as a custom connector in Claude, or as a Streamable HTTP MCP server in ChatGPT. Clients that launch servers from a config file bridge to it with npx mcp-remote.
Setup effort
One command — npx -y mcp-remote https://youtube-transcript.ai/mcp
