# Sleep Cycle Calculator MCP for AI Agents AI Agent Connect > Sleep Cycle Calculator helps you time your rest to match your body's natural 90-minute sleep cycles. It calculates the best times to hit the pillow or jump out of bed so you don't wake up feeling like a zombie. It's built for anyone who wants to stop fighting their internal clock and start waking up refreshed. ## Overview - **Category:** productivity - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_9abnos4ZDTVEl3U33WgsHLPGp0wKRUvzGaRp53Ao/ai-agent-connect - **Tags:** sleep, wellness, optimization, circadian, rest ## Description Waking up feeling like you've been hit by a truck usually happens because you're interrupting a deep sleep cycle. This Connector fixes that by doing the math for you. Instead of guessing when to set your alarm, your AI client can now look at your schedule and figure out the exact windows where you'll feel most alert. It accounts for the time it takes to actually fall asleep, which most basic calculators ignore. You can tell your agent to plan your entire night based on a hard deadline in the morning, or just see if the amount of sleep you're planning actually hits the mark for a full recovery. It's a small piece of logic that makes a huge difference in how you feel when the alarm goes off. If you're looking to organize your wellness routine, this is one of the more practical tools in the Vinkius catalog for getting your biology in sync with your calendar. ## Tools ### calculate_bedtimes Use this to find the best time to go to sleep based on a fixed wake-up time. It ensures you finish a full sleep cycle before your alarm goes off. ### calculate_wake_times Tell your agent when you plan to go to bed to get a list of ideal wake-up options. It helps you pick a time that won't leave you feeling groggy. ### assess_sleep_window Input a total duration of sleep to see if it's actually enough for your body. It categorizes your rest as optimal or insufficient. ## Prompt Examples **Prompt:** ``` I have a flight at 8:00 AM and I want to sleep now. When should I wake up? ``` **Response:** ``` Based on your current time and a 90-minute cycle logic, here are your best wake-up options: * **04:45 AM** (Optimal) * **06:15 AM** (Optimal) * **07:45 AM** (Caution: Very close to your flight) *Tip: Aiming for the 06:15 AM window will likely leave you feeling the most refreshed.* ``` **Prompt:** ``` I need to be at my desk by 9:00 AM. What's the latest I can go to bed? ``` **Response:** ``` To ensure you wake up at the end of a sleep cycle by 9:00 AM, you should aim for these bedtimes: * **11:15 PM** * **12:45 AM** * **02:15 AM** *Note: I recommend the 11:15 PM slot to get the most total rest.* ``` **Prompt:** ``` I just slept for 400 minutes. Was that enough? ``` **Response:** ``` A duration of 400 minutes is **Insufficient** for a full recovery. To hit an optimal window, you should aim for: * **450 minutes** (7.5 hours) * **600 minutes** (10 hours) *Try to get at least 7.5 hours next time to complete four full cycles.* ``` ## Capabilities ### Calculate precise wake-up windows Your agent finds the best times to wake up based on your planned bedtime. ### Determine ideal bedtimes for deadlines Get specific times to go to sleep to hit a mandatory morning wake-up call. ### Verify if sleep duration is sufficient Check if your planned rest time hits the optimal categories for recovery. ### Plan rest around fixed commitments Align your sleep schedule with non-negotiable work or travel deadlines. ### Avoid grogginess from interrupted cycles Ensure your alarm goes off at the end of a cycle to minimize sleep inertia. ## Use Cases ### Traveling across time zones A user asks their agent to find a sleep window that works for a 6am flight. The agent uses calculate_wake_times to find the best rest period. ### Planning a big presentation A user needs to be sharp by 9am. They ask the agent to tell them when to go to bed. The agent uses calculate_bedtimes to suggest a 23:15 bedtime. ### Checking a nap Someone wants to know if a 90-minute nap is enough. They ask the agent to check the duration using assess_sleep_window. ### Shift work management A nurse wants to know when to sleep after a night shift. The agent uses calculate_wake_times to find a window that avoids the groggiest moments. ## Benefits - Stop waking up groggy by using calculate_wake_times to find the end of a natural sleep cycle. - Plan your night perfectly with calculate_bedtimes when you have a non-negotiable morning meeting. - Get immediate feedback on your rest quality by using assess_sleep_window to check your total sleep time. - Remove the guesswork from your wellness routine by letting your agent handle the math of 90-minute cycles. - Improve your daily energy levels by ensuring your sleep duration hits the optimal categories for recovery. ## How It Works The bottom line is you get a scientifically backed sleep schedule that aligns with your actual biological needs. 1. Provide your agent with your planned bedtime or a mandatory wake-up time. 2. The Connector processes the 90-minute sleep cycle logic and 15-minute latency. 3. You get a list of optimal times to sleep or wake up. ## Frequently Asked Questions **How does the Sleep Cycle Calculator help me wake up feeling better?** It calculates your wake-up times based on 90-minute biological cycles. By ensuring you wake up at the end of a cycle rather than in the middle of deep sleep, you avoid that heavy, groggy feeling. **Can I use the Sleep Cycle Calculator to plan my bedtime for a 6am alarm?** Yes. You can tell your agent your required wake-up time, and it will work backward to suggest the best bedtimes that align with your body's natural rhythms. **Does the Sleep Cycle Calculator account for the time it takes to fall asleep?** Yes, it automatically includes a 15-minute sleep latency in its calculations. This ensures the suggested bedtime gives you enough time to actually drift off. **How many sleep cycles does the Sleep Cycle Calculator use for its math?** It uses the standard 90-minute sleep cycle as the basis for all calculations. This helps you find the most natural windows for both falling asleep and waking up. **Can I check if my nap was long enough with the Sleep Cycle Calculator?** You can. By providing the total duration of your nap, the tool will tell you if that amount of rest was optimal or insufficient for a full recovery. **Is the Sleep Cycle Calculator good for shift workers?** It's perfect for shift workers. It helps you identify the best windows to sleep during the day so you can maximize your rest and minimize grogginess before your next shift. **How does the calculator determine wake-up times?** The tool adds a 15-minute sleep latency to your bedtime and then calculates subsequent 90-minute intervals to suggest the best moments to wake up. **Can I check if my current sleep duration is healthy?** Yes, you can use the `assess_sleep_window` tool by providing your total minutes of sleep to see if it falls into optimal, insufficient, or excessive categories. **What format should I use for times?** Please use the 24-hour notation (HH:mm), such as '23:00' or '07:30', for all time-related inputs.
