  The MCP tool handler for 'set_track_input', which registers the tool and calls the reaper adapter.

• src/reaper_mcp/reaper_adapter.py:511-518 (helper)

  The adapter method that communicates with the REAPER client to perform the set_track_input action.

  def set_track_input(
      self, track_index: int, input_index: int
  ) -> dict[str, Any]:
      return self._client.call(
          "set_track_input",

          input_index=input_index,
      )

• src/reaper_mcp/reaper_adapter.py:511-518 (helper)

  ReaperAdapter helper method that calls the bridge client for set_track_input.

  def set_track_input(
      self, track_index: int, input_index: int
  ) -> dict[str, Any]:
      return self._client.call(
          "set_track_input",
