> Circadian Rhythm Aligner generates gradual, actionable schedules for shifting sleep and wake times. This MCP helps you avoid the shock of sudden schedule changes by planning out small, manageable adjustments day-by-day. It ensures your new routine maintains healthy rest durations while tracking the exact time shift required for a smooth transition back to a stable circadian rhythm.

## Description

Trying to shift your sleep schedule is tough; doing it overnight usually leads to feeling terrible. This MCP handles that complexity by building realistic, step-by-step plans so you don't have to deal with sudden changes. You input your old bedtime and wake time, and the agent figures out how many days it will take to reach your target. It generates a day-by-day schedule that shifts everything in small increments—say, 15 or 30 minutes at a time. Beyond just setting times, it analyzes whether your new window still gives you enough rest time overall. If you’re managing complex routines, connecting to the Vinkius catalog means all these specialized tools are available through one place. You simply connect your preferred AI client and start planning your sleep cycle recovery.

## Prompt Examples

**Prompt:** 
```
I'm moving from 12 AM to 9 AM to 7 AM. Can you map out the gradual plan using 30-minute shifts?
```

**Response:** 
```
**Circadian Transition Plan**

*   **Start:** Bedtime 12:00 AM / Wake 9:00 AM
*   **Target:** Bedtime 11:00 PM / Wake 7:00 AM

The shift requires 3 days of gradual adjustment:

| Day | Bedtime | Wake Time |
| :---: | :---: | :---: |
| **Day 1** | 11:30 PM | 8:30 AM |
| **Day 2** | 11:00 PM | 7:30 AM |
| **Day 3** | 11:00 PM | 7:00 AM |

*Note: All windows maintain a minimum of 8 hours of rest.*
```

**Prompt:** 
```
If I shift from 7 AM to 2 PM, what's the total time difference in minutes?
```

**Response:** 
```
**Drift Magnitude Calculation**
The total temporal shift required for this transition is **1920 minutes** (or 32 hours). This figure represents the full minute-by-minute gap between your current and desired schedule.
```

**Prompt:** 
```
I want to move from my current schedule to a target of 8:30 PM / 6:30 AM. Is that window healthy?
```

**Response:** 
```
**Sleep Window Integrity Check**

*   **Proposed Window:** 8:30 PM - 6:30 AM
*   **Calculated Duration:** 10 hours
*   **Minimum Requirement (User Set):** 7 hours

✅ **Result: Healthy.** This schedule provides a comfortable margin above the minimum recommended duration, suggesting low risk of sleep deprivation.
```

## Capabilities

### Generate gradual sleep adjustment plans
The MCP creates a day-by-day schedule that shifts both bedtime and wake time using small, specific increments.

### Check for healthy sleep window integrity
It analyzes proposed schedules to confirm the minimum required duration of rest is met consistently.

### Determine total temporal shift
The system calculates the overall magnitude, or total minutes, that your current schedule needs to move.

## Use Cases

### Returning home from international travel
After spending two weeks in London, an agent asks for a plan to shift the sleep window back to EST. The MCP uses `calculate_adjustment_plan` and delivers a 5-day schedule, making the transition manageable instead of grueling.

### Starting a new night-shift job
A factory worker needs to move from an 8 AM wake time to a 4 PM wake time. The agent uses `calculate_drift_magnitude` first, then builds the transition plan, allowing them to adjust slowly over two weeks.

### Diagnosing sleep deprivation risk
A user inputs an aggressive schedule (1 AM to 6:30 AM). The MCP uses `analyze_sleep_window_integrity` and instantly flags that the window falls below the critical 7-hour threshold, advising against the change.

### Adjusting for seasonal changes
A user wants to naturally shift their schedule back in autumn. The MCP uses `calculate_adjustment_plan` to create a gentle, multi-week plan that respects the body's natural rhythm change.

## Benefits

- Avoid sudden schedule shock: The `calculate_adjustment_plan` tool builds a step-by-step timeline, so you never have to wake up or go to bed at a drastically different time.
- Ensure consistent rest: Using `analyze_sleep_window_integrity`, you can check any potential schedule before committing to it and confirm that the sleep duration remains healthy.
- Know your total shift: The MCP immediately gives you the `calculate_drift_magnitude` needed, eliminating guesswork about how far off your current rhythm is from the target.
- Manage time zones safely: Traveling across multiple time zones becomes predictable. You get a clear path back to local sleep patterns without crashing.
- Stop guessing routines: Instead of manually calculating small shifts over weeks, you pass the variables and receive a full, actionable schedule instantly.

## How It Works

The bottom line is that you get a clear timeline showing exactly when to adjust your sleep habits to reach your desired rhythm without stress.

1. You provide your current sleep times and the target time you want to achieve.
2. The MCP first figures out the total shift needed and then calculates the minimum number of days required for a gradual transition.
3. Finally, it delivers a full schedule plan, detailing the specific bedtime and wake time for each day until the goal is met.

## Frequently Asked Questions

**How does Circadian Rhythm Aligner help me adjust after moving across time zones?**
It builds a phased plan that breaks down the total required shift into small, manageable daily increments. Instead of forcing an immediate change, it gives you a gradual timeline to realign your body clock safely.

**Can I use Circadian Rhythm Aligner if I'm working night shifts?**
Yes. It handles the unique challenge of shift workers by creating schedules that guide you back to a normal rhythm, day by day, minimizing sleep disruption and fatigue.

**What happens if my target schedule is too short for proper rest?**
The tool runs integrity checks on any proposed window. If the duration falls below your minimum required hours of sleep, it flags the risk immediately so you don't commit to an unhealthy routine.

**Is Circadian Rhythm Aligner better than just calculating time difference?**
Yes. While a simple calculation only gives you a number (the total shift), this MCP provides the actual action plan, telling you exactly what time to go to bed and wake up every single day.

**Does Circadian Rhythm Aligner account for different increment sizes?**
Absolutely. You can specify whether you want your schedule to shift in 15-minute or 30-minute increments, making the plan tailored precisely to how gentle you need the transition to be.
