Cursor Pagination Returns Duplicate Content

Bug Report: Cursor Pagination Returns Duplicate Content

Summary

The MCP youtube-transcript server returns duplicate transcript segments when pagination cursor points to the end position. The server returns the same next_cursor value it received, causing infinite loops if not explicitly handled by clients.

Environment

  • Package: mcp-youtube-transcript (Docker image: mcp/youtube-transcript)
  • Client: MCP SDK TypeScript client
  • Docker container run with: `docker run --rm -i mcp

  • Updated error handling and sanitization

Resource Protection

  • Memory usage controls

Include description and channel in JSON metadata

It'd be awesome if, in addition to title, you could include the description and channel in the response JSON as well.

Thanks for the great tool!

Plugin is broken for anyone who doesn't have bun on their host machine

Hey! I went to use your extension/MCP server yesterday during a workshop by one of the Goose team members.

I went to install your MCP server via Goose and got an error about Bun not existing on the machine. About 10 mins later a different attendee ran into the same issue, but I was able to help them through it.

Once we installed Bun, things worked fine. I was surprised that Bun was a requirement of the host machine.

Feature Request: Support for configurable language preference in get_transcript()

Description The get_transcript() tool currently only searches for English transcripts by default, making it impossible to retrieve transcripts in other languages (e.g., German, French, Spanish) even when they are available on YouTube. ## Current Behavior When calling get_transcript(url) on a video that has only non-English transcripts but no English transcript, the tool fails with:

No transcripts were found for any of the requested language codes: ['en']

The tool only looks for English (

Capturing timestamp information

Hi there. I found out about your MCP from the Docker MCP page. It works like a charm! Thanks for building it out. I'm not sure if this is appropriate, but I just wanted to suggest a feature enhancement. No problem at all if you're not taking them. If you are, it would be valuable if timestamp information could be included with the transcript (assuming it's provided in the video description).

Thanks!
