Implementation Reference

• mcp/tools/bazi_handlers.py:84-104 (handler)

  The main handler function that implements the core logic for the get_bazi_chart tool. It validates input parameters, builds birth information, retrieves the Bazi chart from the system, and formats the output.

  @log_performance
  def handle_get_bazi_chart(args: Dict[str, Any]) -> str:
      """工具：获取八字排盘"""

      )
  
      with PerformanceTimer("八字排盘"):
          birth_info = _build_birth_info(args)
