Managing sleep debt requires biological precision. Artificial Intelligence models generally lack an understanding of human circadian rhythms, suggesting arbitrary '8 hours of sleep' that interrupt deep REM phases and cause morning grogginess. The Circadian REM Optimizer processes strict chronobiology rules natively.

Core Value Add

  • REM Phase Harmonization: Computes exact timestamps mapped to natural 90-minute sleep cycles (from 3 to 6 cycles), ensuring you always wake up during light sleep stages.
  • Latency Buffering Engine: Standard sleep math ignores sleep latency. This MCP integrates an adjustable 'fall asleep' buffer (default 15 minutes) into the backward/forward timeline progression.
  • Bidirectional Architecture: Supports both 'wake_up_at' (backward deduction) and 'sleep_at' (forward projection) modes to fit rigid alarm schedules or flexible weekend chronotypes.
  • Zero-Dependency Native Code: The mathematical projection happens securely within the V8 engine, maintaining high-speed responsiveness for health-tech AI workflows.

4 tools expose this connector's capabilities to your AI agent.

calculate_nap_times

Requires wake-up time in HH:mm. Calculates the ideal window for power naps based on wake-up time

calculate_sleep_cycles

Provide a targetTimeStr (HH:mm) and the mode (sleep_at or wake_up_at). Calculates optimal wake-up or bedtimes aligned with 90-minute REM sleep phases, incorporating latency buffers for circadian rhythm optimization

calculate_sleep_debt

Requires daily required hours and an array of actually slept hours. Calculates accumulated sleep debt and provides an actionable recovery strategy

calculate_circadian_rhythm

Maps out energy peaks and troughs throughout the day based on wake time

See how to talk to your AI agent using Circadian REM Sleep Cycle Optimizer.

I need to wake up at 06:30 for work. What are the best times to go to sleep?

Using the calculate_sleep_cycles tool (mode: wake_up_at): The optimal time to get into bed for 6 complete REM cycles is 21:15. For 5 cycles, aim for 22:45. Both times account for a 15-minute sleep latency buffer.

I am going to sleep right now at 23:00. When should I set my alarm?

Using the calculate_sleep_cycles tool (mode: sleep_at): To align with optimal REM phases, you should set your alarm for 06:45 (5 cycles) or 08:15 (6 cycles).

Calculate a wake-up schedule for 05:00 assuming it takes me 30 minutes to fall asleep.

Using the calculate_sleep_cycles tool: The circadian engine confirms that for a 05:00 wake-up with a 30-minute latency, you must get into bed exactly at 21:00 for 5 complete REM cycles.

Human sleep cycles last approximately 90 minutes. Waking up in the middle of a deep REM phase causes 'sleep inertia' (grogginess). This algorithm targets wake-up times strictly at the end of a cycle, meaning sleeping 7.5 hours (5 cycles) often feels more refreshing than sleeping 8 hours.
