Implementation Reference
- src/services/sun-service.ts:70-98 (handler)Core implementation of getSunTimesRange that computes sun times over a date range using SunCalc library, looping daily and calling getSunTimes.
getSunTimesRange(params: SunTimesRangeParams): SunTimesInfo[] { const startDate = new Date(params.start_date); const endDate = new Date(params.end_date); if (isNaN(startDate.getTime()) || isNaN(endDate.getTime())) { throw new Error('Invalid date format. Please use YYYY-MM-DD format.'); } if (startDate > endDate) { throw new Error('Start date must be before end date.'); } const result: SunTimesInfo[] = []; const currentDate = new Date(startDate); while (currentDate <= endDate) { result.push(this.getSunTimes({ date: currentDate.toISOString().split('T')[0], latitude: params.latitude, longitude: params.longitude, timezone: params.timezone })); // Move to next day currentDate.setDate(currentDate.getDate() + 1); } return result; } - src/interfaces/sun.ts:20-29 (schema)Zod schema definition for the input parameters of the get_sun_times_range tool.
export const SunTimesRangeParamsSchema = z.object({ start_date: z.string().describe('Start date (YYYY-MM-DD format)'), end_date: z.string().describe('End date (YYYY-MM-DD format)'), latitude: z.number().min(-90).max(90).describe('Latitude for location-specific calculations'), longitude: z.number().min(-180).max(180).describe('Longitude for location-specific calculations'), format: z.enum(['json', 'text']).optional().describe('Output format (json or text)'), timezone: z.string().optional().describe('Timezone for the results. Defaults to UTC.') }); export type SunTimesRangeParams = z.infer<typeof SunTimesRangeParamsSchema>; - src/tools/sun-tools.ts:43-70 (registration)MCP tool registration for 'get_sun_times_range', including description, input schema reference, and execute handler that delegates to SunService.
