playCompletionSound

Implementation Reference

• src/index.ts:18-33 (handler)

  The handler function for the 'playCompletionSound' tool. It plays a macOS system sound using the 'play-sound' library and returns a success or failure message in the MCP response format.

  async () => {
    try {
      // Play macOS system sound
      audioPlayer.play(SYSTEM_SOUND, (err: Error | null) => {
        if (err) console.error('Error playing sound:', err);
      });
      return {
        content: [{ type: 'text', text: 'Played completion sound' }]
      };
    } catch (error) {
      console.error('Failed to play sound:', error);
      return {
        content: [{ type: 'text', text: 'Failed to play sound' }]
      };
    }
  }

• src/index.ts:15-34 (registration)

  Registers the 'playCompletionSound' tool with the MCP server, using an empty schema and the inline handler function.

  server.tool(
    'playCompletionSound',
    {},
    async () => {
      try {
        // Play macOS system sound
        audioPlayer.play(SYSTEM_SOUND, (err: Error | null) => {
          if (err) console.error('Error playing sound:', err);
        });
        return {
          content: [{ type: 'text', text: 'Played completion sound' }]
        };
      } catch (error) {
        console.error('Failed to play sound:', error);
        return {
          content: [{ type: 'text', text: 'Failed to play sound' }]
        };
      }
    }
  );

• src/index.ts:3-6 (helper)

  Helper code that imports the 'play-sound' module, initializes the audio player, and defines the path to the macOS Glass.aiff system sound used by the tool handler.

  import player from 'play-sound';
  
  const audioPlayer = player();
  const SYSTEM_SOUND = '/System/Library/Sounds/Glass.aiff'; // macOS system sound
