• src/sketchup_mcp/server.py:256-290 (handler)

  The handler function for the 'create_component' tool. It is registered via the @mcp.tool() decorator. The function proxies the tool call to SketchUp's own 'create_component' tool by sending a JSON-RPC request over a socket connection.

  @mcp.tool()
  def create_component(
      ctx: Context,
      type: str = "cube",
      position: List[float] = None,
      dimensions: List[float] = None
  ) -> str:
      """Create a new component in Sketchup"""
      try:
          logger.info(f"create_component called with type={type}, position={position}, dimensions={dimensions}, request_id={ctx.request_id}")
          
          sketchup = get_sketchup_connection()
          
          params = {
              "name": "create_component",
              "arguments": {
                  "type": type,
                  "position": position or [0,0,0],
                  "dimensions": dimensions or [1,1,1]
              }
          }
          
          logger.info(f"Calling send_command with method='tools/call', params={params}, request_id={ctx.request_id}")
          
          result = sketchup.send_command(
              method="tools/call",
              params=params,
              request_id=ctx.request_id
          )
          
          logger.info(f"create_component result: {result}")
          return json.dumps(result)
      except Exception as e:
          logger.error(f"Error in create_component: {str(e)}")
