Implementation Reference

• src/server.ts:736-803 (handler)

  Handler function for the 'get_calendar_events' tool. Parses input parameters, determines calendar type and date range, calls the API to fetch schedule events, and returns formatted JSON response with error handling.
  case "get_calendar_events": try { const { calendar_type, from_date, to_date, period } = args as { calendar_type?: string; from_date?: string; to_date?: string; period?: string; }; // Determine calendar type const calendarType = calendar_type === "school" ? CalendarType.SCHOOL : CalendarType.PERSONAL; // Determine date range let dateRange; if (period) { switch (period) { case "today": { const today = new Date(); dateRange = this.api.createSingleDayRange(today); break; } case "week": dateRange = this.api.createWeekDateRange(); break; case "month": dateRange = this.api.createMonthDateRange(); break; default: throw new Error(`Invalid period: ${period}`); } } else if (from_date && to_date) { dateRange = this.api.createDateRange(from_date, to_date); } else if (from_date) { // Single day range dateRange = this.api.createSingleDayRange(from_date); } // If no date parameters, use default (current week) const schedule = await this.api.getSchedule( calendarType, dateRange, ); return { content: [ { type: "text", text: `[DATE] Calendar Events (${calendar_type || "personal"})${ dateRange ? ` from ${dateRange.from.toDateString()} to ${dateRange.to.toDateString()}` : " (current week)" }\n\n${JSON.stringify(schedule, null, 2)}`, }, ], }; } catch (error) { return { content: [ { type: "text", text: `Error: ${error instanceof Error ? error.message : "Unknown error"}\n\nTo authenticate:\n1. Login to N Lobby in your browser\n2. Open Developer Tools (F12)\n3. Go to Application/Storage tab\n4. Copy cookies and use the set_cookies tool\n5. Use health_check to verify connection`, }, ], }; }
