Implementation Reference

• src/adb_mcp_server/server.py:219-240 (handler)

  The main handler function for the 'pull_recordings' tool. It lists MP4 files in /sdcard/, pulls them using adb pull to the specified local directory, and returns the list of pulled files.

  @mcp.tool()
  def pull_recordings(
      local_dir: str = "./recordings",
      device_serial: str | None = None
  ) -> str:
      """Pull all screen recordings from device to local directory"""
      os.makedirs(local_dir, exist_ok=True)
      
      # List recordings
      files = run_adb(["shell", "ls", "/sdcard/*.mp4"], device_serial)
      if "No such file" in files or not files.strip():
          return "No recordings found on device"
      
      pulled = []
      for f in files.strip().split('\n'):
          f = f.strip()
          if f.endswith('.mp4'):
              local_path = os.path.join(local_dir, os.path.basename(f))
              run_adb(["pull", f, local_path], device_serial)
              pulled.append(local_path)
      
      return f"Pulled {len(pulled)} recordings to {local_dir}: {pulled}"
