Implementation Reference

• src/index.ts:176-195 (handler)

  The tool registration and handler logic for 'get_youtube_feed'. It validates input parameters, calls 'fetchFeed', and processes the result using 'pickVideoFields'.

  server.tool(
    'get_youtube_feed',
    'Fetch videos from your YouTube account using Chrome cookies. Supports: subscriptions, liked, watch_later, history.',
    {
      feed: z.enum(['subscriptions', 'liked', 'watch_later', 'history']).describe('Which feed to fetch'),
      limit: z.number().min(1).max(50).default(15).describe('Max number of videos to return (default 15)'),
    },
    async ({ feed, limit }) => {
      const depErr = checkDeps();
      if (depErr) return errorResult(depErr);
  
      try {
        const result = await fetchFeed(FEED_URLS[feed], limit);
        const videos = (result.entries || []).map(pickVideoFields);
        return textResult({ feed, count: videos.length, videos });
      } catch (err) {
        return errorResult(`Error fetching ${feed}: ${err instanceof Error ? err.message : String(err)}`);
      }
    }
  );

• src/ytdlp.ts:39-53 (helper)

  The core logic that fetches the YouTube feed data by spawning 'yt-dlp' with appropriate arguments.

  export function fetchFeed(url: string, limit: number, start = 1): Promise<YtFeedResult> {
    const args = [
      url, '-J', '--flat-playlist',
      '--playlist-start', String(start),
      '--playlist-end', String(start + limit - 1),
      '--cookies-from-browser', getBrowser(),
    ];
  
    // YouTube-specific extractor arg
    if (url.includes('youtube.com') || url.includes('youtu.be')) {
      args.push('--extractor-args', 'youtubetab:approximate_date');
    }
  
    return spawnYtDlp(args).then((out) => JSON.parse(out));
  }
