Flight Ticket MCP Server

Instructions

Implementation Reference

• flight_ticket_mcp_server/main.py:226-231 (handler)

  MCP tool handler for 'getCurrentDate' registered with @mcp.tool() decorator. This is the entry point executed when the tool is called, delegating to date_tools.getCurrentDate().

  @mcp.tool()
  def getCurrentDate():
      """获取当前日期 - 返回格式为 yyyy-MM-dd 的当前日期字符串"""
      logger.debug("调用获取当前日期工具")
      return date_tools.getCurrentDate()

• flight_ticket_mcp_server/main.py:226-231 (registration)

  Registration of the 'getCurrentDate' tool via FastMCP @mcp.tool() decorator within the register_tools() function.

  @mcp.tool()
  def getCurrentDate():
      """获取当前日期 - 返回格式为 yyyy-MM-dd 的当前日期字符串"""
      logger.debug("调用获取当前日期工具")
      return date_tools.getCurrentDate()

• flight_ticket_mcp_server/tools/date_tools.py:51-79 (helper)

  Core helper function implementing getCurrentDate logic, called by the MCP handler. Returns a dictionary with current date, datetime, timestamp, and query time.

  def getCurrentDate() -> Dict[str, Any]:
      """
      获取当前日期的工具函数
      
      Returns:
          Dict[str, Any]: 包含当前日期信息的字典
      """
      try:
          current_date = DateTools.get_current_date()
          current_datetime = DateTools.get_current_datetime()
          
          result = {
              "status": "success",
              "current_date": current_date,
              "current_datetime": current_datetime,
              "timestamp": datetime.now().timestamp(),
              "query_time": datetime.now().isoformat()
          }
          
          logger.info(f"获取当前日期成功: {current_date}")
          return result
          
      except Exception as e:
          logger.error(f"获取当前日期失败: {str(e)}", exc_info=True)

              "error_code": "GET_DATE_FAILED"
          } 

• flight_ticket_mcp_server/tools/date_tools.py:19-33 (helper)

  Low-level static method in DateTools class that retrieves the current date as a formatted string (yyyy-MM-dd), used by getCurrentDate() helper.

  def get_current_date() -> str:
      """
      获取当前日期
      
      Returns:
          str: 当前日期，格式为 yyyy-MM-dd

          current_date = datetime.now().strftime("%Y-%m-%d")

          raise e

• flight_ticket_mcp_server/tools/date_tools.py:35-48 (helper)

  Low-level static method in DateTools class that retrieves the current date and time as a formatted string (yyyy-MM-dd HH:mm:ss), used by getCurrentDate() helper.

  def get_current_datetime() -> str:
      """
      获取当前日期和时间
