Implementation Reference

• src/reaper_mcp/server.py:354-377 (handler)

  The handler function for the `set_midi_notes` tool, which wraps the adapter call.

  @mcp.tool()
  def set_midi_notes(
      track_index: int,
      item_index: int,
      notes: list[dict[str, Any]],
  ) -> dict[str, Any]:
      """
      Batch-edit multiple MIDI notes in one call. More efficient than calling
      set_midi_note() repeatedly.
      Each entry in 'notes' must have 'note_index' and any subset of:
        pitch, velocity, start_ppq, end_ppq, channel, selected, muted.
      Omitted fields keep their current values.
      """
      try:
          return _wrap(
              adapter.set_midi_notes(
                  track_index=track_index,
                  item_index=item_index,

• src/reaper_mcp/server.py:354-354 (registration)

  @mcp.tool()

• src/reaper_mcp/reaper_adapter.py:197-208 (helper)

  The adapter implementation that forwards the `set_midi_notes` request to the bridge client.

      self,
      track_index: int,
      item_index: int,
