# Sleep Debt Calculator MCP for AI Agents MCP > Sleep Debt Calculator lets you track your missing rest, figure out how many nights of extra sleep you need to catch up, and find the best times to nap without feeling like a zombie. It turns your messy sleep logs into a concrete recovery plan based on your age and caffeine habits. ## Overview - **Category:** productivity - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_n3feDcZF4RQIoL1fmzODuVRNW8KbuC2hptdXC0yp/mcp - **Tags:** sleep, health-tracking, recovery, caffeine, analytics ## Description Most people just know they're tired. They don't know if they're actually sleep-deprived or just hitting a wall. This MCP changes that by turning vague feelings into actual numbers. You can feed it your sleep history from the past week, and it'll tell you exactly how many hours you're behind based on your age. It doesn't just stop at the "how much" part, though. It actually helps you plan the way back to feeling normal. If you want to know how many nights of extra sleep it'll take to clear the deck, it'll give you that timeline. It even looks at your caffeine intake to tell you when a nap won't leave you feeling groggy. It's a useful addition to the Vinkius catalog because it bridges the gap between "I need to sleep more" and "here is the specific plan to do it." You get a clear picture of your cognitive performance drops and a schedule that works with your actual life, not just a generic sleep 8 hours suggestion. ## Tools ### calculate_sleep_debt Tells you the total hours of sleep you're missing from the last week. ### evaluate_cognitive_impact Gives you a percentage of how much your brain power has dropped. ### forecast_recovery_timeline Predicts how many nights of extra sleep you need to reach specific goals. ### schedule_nap_remedy Tells you the best time to nap based on your last caffeine hit. ## Prompt Examples **Prompt:** ``` I'm 30. I slept 5 hours every night this week. How much debt do I have? ``` **Response:** ``` Your total accumulated sleep debt is 10 hours. Based on your age, your sleep consistency is rated as **Poor**. ``` **Prompt:** ``` I have 8 hours of debt. If I sleep 2 extra hours a night, when am I done? ``` **Response:** ``` You'll reach full recovery in **4 nights**. You can expect to reach the fifty percent reduction milestone in 2 nights. ``` **Prompt:** ``` I had a coffee at 1 PM. I'm tired now. When should I nap? ``` **Response:** ``` Since your caffeine levels are still active, a recommended nap window is between **4:30 PM and 5:00 PM** for a duration of 25 minutes. Note that caffeine is still high enough to potentially interfere with deep sleep. ``` ## Capabilities ### Calculate total hours of missing sleep It determines exactly how much rest you're behind based on your weekly logs. ### Predict nights of extra rest needed It tells you how many nights of surplus sleep you need to hit specific recovery goals. ### Estimate percentage of brain fog It gives you a number on how much your fatigue is actually affecting your cognitive performance. ### Find optimal nap windows for caffeine It suggests the best time to nap based on your last caffeine hit to avoid grogginess. ### Track sleep consistency over time It monitors your sleep patterns to help you identify erratic habits. ## Use Cases ### The afternoon slump A worker feels a slump at 3 PM and asks their agent for a nap window that won't ruin their night sleep.
