Implementation Reference
- MCP_Server/server.py:674-683 (handler)The primary MCP tool handler for 'stop_recording'. It retrieves the Ableton connection, sends the 'stop_recording' command, and returns a formatted status message. The @mcp.tool() decorator also serves as the registration.@mcp.tool() def stop_recording(ctx: Context) -> str: try: ableton = get_ableton_connection() result = ableton.send_command("stop_recording") status = "recording" if result.get('recording') else "not recording" return f"Stopped recording - Status: {status}, Playing: {result.get('playing')}" except Exception as e: logger.error(f"Error stopping recording: {str(e)}") return f"Error stopping recording: {str(e)}"
- The underlying implementation in the Ableton Live remote script that handles the 'stop_recording' command by stopping playback (which ends recording) and returning the updated recording and playing status.def _stop_recording(self): """Stop recording""" try: # Stop recording and playback self._song.stop_playing() result = { "recording": False, "playing": self._song.is_playing } return result except Exception as e: self.log_message("Error stopping recording: " + str(e))
- MCP_Server/server.py:196-249 (helper)Utility function used by the handler to obtain a persistent socket connection to the Ableton remote script server.def get_ableton_connection(): """Get or create a persistent Ableton connection""" global _ableton_connection if _ableton_connection is not None: try: # quick liveness test (non-intrusive) _ableton_connection.sock.settimeout(0.5) _ableton_connection.sock.send(b'') # may raise if broken _ableton_connection.sock.settimeout(None) return _ableton_connection except Exception as e: logger.warning(f"Existing connection is no longer valid: {str(e)}") try: _ableton_connection.disconnect() except Exception: pass _ableton_connection = None # Try to establish a new persistent connection (retries) max_attempts = 3 for attempt in range(1, max_attempts + 1): try: logger.info(f"Connecting to Ableton (attempt {attempt}/{max_attempts})...") candidate = AbletonConnection(host="localhost", port=9877) if candidate.connect(): _ableton_connection = candidate # basic validation try: _ableton_connection.send_command("get_session_info") logger.info("Connection validated successfully") return _ableton_connection except Exception as e: logger.error(f"Connection validation failed: {str(e)}") _ableton_connection.disconnect() _ableton_connection = None else: _ableton_connection = None except Exception as e: logger.error(f"Connection attempt {attempt} failed: {str(e)}") if _ableton_connection: try: _ableton_connection.disconnect() except Exception: pass _ableton_connection = None if attempt < max_attempts: import time time.sleep(1.0) logger.error("Failed to connect to Ableton after multiple attempts") raise Exception("Could not connect to Ableton. Make sure the Remote Script is running and Ableton is open.")
