Implementation Reference

• src/index.ts:820-839 (handler)

  The handler function for the 'get-current-date' tool. It retrieves the current date in the Asia/Shanghai timezone using date-fns-tz.toZonedTime and date-fns.format, and returns it formatted as 'yyyy-MM-dd' in the MCP response format.

          try {
              const timeZone = 'Asia/Shanghai';
              const nowInShanghai = toZonedTime(new Date(), timeZone);
              const formattedDate = format(nowInShanghai, 'yyyy-MM-dd');
              return {
                  content: [{ type: 'text', text: formattedDate }],
              };
          } catch (error) {
              console.error('Error getting current date:', error);
              return {
                  content: [
                      {
                          type: 'text',
                          text: 'Error: Failed to get current date.',
                      },

          }
      }
  );
