Implementation Reference

• src/index.ts:130-148 (handler)

  The implementation of the 'prev_video' MCP tool, which executes 'playlist-prev' via the mpv command and returns the new video's status, title, and position.

  server.tool(
    'prev_video',
    'Go back to the previous video in the current playlist.',
    {},
    async () => {
      try {
        await mpv.command(['playlist-prev']);
        await new Promise((r) => setTimeout(r, 1000));
        const [title, pos, count] = await Promise.all([
          mpv.getProperty('media-title'),
          mpv.getProperty('playlist-pos'),
          mpv.getProperty('playlist-count'),
        ]);
        return textResult({ status: 'skipped_prev', title, position: `${Number(pos) + 1}/${count}` });
      } catch (err) {
        return errorResult(`Error: ${err instanceof Error ? err.message : String(err)}`);
      }
    }
  );
