• src/akshare_one_mcp/server.py:252-273 (handler)

  The handler function for the 'get_time_info' tool, decorated with @mcp.tool which also serves as registration. It fetches the current time, timestamp, and the last trading day using akshare's trading calendar.

  @mcp.tool
  def get_time_info() -> dict:
      """Get current time with ISO format, timestamp, and the last trading day."""
      local_time = datetime.now().astimezone()
      current_date = local_time.date()
  
      # Get trading calendar
      trade_date_df = ak.tool_trade_date_hist_sina()
      trade_dates = [d for d in trade_date_df["trade_date"]]
  
      # Filter dates <= current date and sort descending
      past_dates = sorted([d for d in trade_dates if d <= current_date], reverse=True)
  
      # Find the most recent trading day
      last_trading_day = past_dates[0].strftime("%Y-%m-%d") if past_dates else None
  
      return {
          "iso_format": local_time.isoformat(),
          "timestamp": local_time.timestamp(),
          "last_trading_day": last_trading_day,
      }
