AbletonMCP

Implementation Reference

• MCP_Server/server.py:326-339 (handler)

  MCP server tool handler for 'set_clip_name'. Proxies the call to the Ableton remote script via socket command.

  @mcp.tool()
  def set_clip_name(ctx: Context, track_index: int, clip_index: int, name: str) -> str:
      try:
          ableton = get_ableton_connection()
          result = ableton.send_command("set_clip_name", {
              "track_index": track_index,
              "clip_index": clip_index,
              "name": name
          })
          return f"Renamed clip at track {track_index}, slot {clip_index} to '{name}'"
      except Exception as e:
          logger.error(f"Error setting clip name: {str(e)}")
          return f"Error setting clip name: {str(e)}"

• AbletonMCP_Remote_Script/__init__.py:613-638 (handler)

  Backend handler in Ableton remote script that performs the actual clip renaming using Ableton Live API: clip.name = name

  def _set_clip_name(self, track_index, clip_index, name):
      """Set the name of a clip"""
      try:
          if track_index < 0 or track_index >= len(self._song.tracks):
              raise IndexError("Track index out of range")
          
          track = self._song.tracks[track_index]
          
          if clip_index < 0 or clip_index >= len(track.clip_slots):
              raise IndexError("Clip index out of range")
          
          clip_slot = track.clip_slots[clip_index]
          
          if not clip_slot.has_clip:
              raise Exception("No clip in slot")
          
          clip = clip_slot.clip
          clip.name = name
          
          result = {
              "name": clip.name
          }
          return result
      except Exception as e:
          self.log_message("Error setting clip name: " + str(e))
          raise

• AbletonMCP_Remote_Script/__init__.py:261-265 (registration)

  Command dispatch registration in remote script that maps incoming 'set_clip_name' socket command to the backend handler.

  elif command_type == "set_clip_name":
      track_index = params.get("track_index", 0)
      clip_index = params.get("clip_index", 0)
      name = params.get("name", "")
      result = self._set_clip_name(track_index, clip_index, name)

• MCP_Server/server.py:106-106 (helper)

  Lists 'set_clip_name' as a modifying command that receives extra timeout handling in socket communication.
