Implementation Reference

• src/main.ts:316-332 (handler)

  Handler function for the 'add_track' tool: loads the MIDI file, adds a new track using midi.addTrack(), saves the file, and returns the new track info as JSON string.

  withErrorHandling(({ filePath }) => {
      // 读取文件
      const midi = loadMidiFile(filePath)
      // 添加新轨道
      const newTrack = midi.addTrack()
      // 保存文件
      saveMidiFile(midi, filePath)
  
      return {
          content: [
              {
                  type: 'text',
                  text: JSON.stringify(newTrack),
              },
          ]
      }
  })

• src/main.ts:313-315 (schema)

  Input schema for 'add_track' tool, requiring absolute file path to the MIDI file.

  {
      filePath: z.string().describe('Absoulate File Path to midi file'),
  },

• src/main.ts:310-333 (registration)

  Registration of the 'add_track' tool with server.tool, including description, input schema, and handler.

  server.tool(
      'add_track',
      'Add a new track to midi file and return the new track info',
      {
          filePath: z.string().describe('Absoulate File Path to midi file'),
      },
      withErrorHandling(({ filePath }) => {
          // 读取文件
          const midi = loadMidiFile(filePath)
          // 添加新轨道
          const newTrack = midi.addTrack()
          // 保存文件
          saveMidiFile(midi, filePath)
  
          return {
              content: [
                  {
                      type: 'text',
                      text: JSON.stringify(newTrack),
                  },
              ]
          }
      })
