Using Docker

A Docker image for this server is available on Docker Hub. Please refer to the Docker Hub page for detailed usage instructions and documentation.

Response Pagination

When retrieving transcripts for longer videos, the content may exceed the token size limits of the LLM. To avoid this issue, this server splits transcripts that exceed 50,000 characters. If a transcript is split, the response will include a next_cursor. To retrieve the next part, include this next_cursor value in your request.

The token size limits vary depending on the LLM and language you are using. If you need to split responses into smaller chunks, you can adjust this using the --response-limit command line argument. For example, the configuration below splits responses to contain no more than 15,000 characters each:

{
  "mcpServers": {
    "youtube-transcript": {
      "command": "uvx",
      "args": [
        "--from",
        "git+https://github.com/jkawamoto/mcp-youtube-transcript",
        "mcp-youtube-transcript",
        "--response-limit",
        "15000"
      ]
    }
  }
}

Using Proxy Servers

In environments where access to YouTube is restricted, you can use proxy servers.

When using Webshare, set the username and password for the Residential Proxy using either the environment variables WEBSHARE_PROXY_USERNAME and WEBSHARE_PROXY_PASSWORD, or the command line arguments --webshare-proxy-username and --webshare-proxy-password.

When using other proxy servers, set the proxy server URL using either the environment variables HTTP_PROXY or HTTPS_PROXY, or the command line arguments --http-proxy or --https-proxy.
