# Blue Light Exposure Timer MCP. AI Agent Connect > Blue Light Exposure Timer MCP helps you manage your circadian rhythm by calculating optimal light exposure windows. Your AI client uses this to find ideal screen cutoff times, evaluate melatonin suppression risks, and build morning alertness plans based on your specific device usage and sleep goals. ## Overview - **Category:** productivity - **Price:** Free - **Endpoint:** https://edge.vinkius.com/vk_preview_3UGaV7IAsgjxDFnWKSkn6gFYDKdqTGVTjJdu87mW/ai-agent-connect - **Tags:** sleep, circadian, melatonin, blue-light, wellness ## Description You can't control the sun, but you can control how your devices mess with your biology. This MCP gives your AI client the data it needs to help you manage your circadian rhythm. Instead of guessing when to put the phone away, you get specific cutoff times and light guidance tailored to your actual sleep schedule. It looks at how you use your screens, the brightness levels you prefer, and your morning routines to build a plan that keeps your melatonin levels where they need to be. Whether you need to know if you should buy blue light blocking glasses or if a high-LUX light box will help you wake up, your agent can run the numbers for you. It turns your sleep goals into a practical, hour-by-hour light management strategy. ## Tools ### get_exposure_risk_assessment This tool evaluates how much your device usage might disrupt your sleep. It calculates the physiological risk of melatonin suppression based on your specific habits. ### get_filter_requirements This tool determines if you need technical help to protect your eyes. It tells you if software filters or hardware mitigations are necessary for your setup. ### get_morning_alertness_plan This tool builds a plan to help you wake up. It focuses on morning alertness and anchoring your circadian rhythm through light exposure. ### get_sleep_schedule_recommendations This tool provides a full schedule of light-related activities. It maps out your day based on your specific sleep goals and light needs. ## Prompt Examples **Prompt:** ``` I want to go to bed at 22:30 and wake up at 06:30. I use my phone with medium brightness. What is my light schedule? ``` **Response:** ``` Your screen cutoff time is 21:00. For the evening, use dim warm lights only. Your morning light window is from 06:30 to 07:30, and you should use natural sunlight if possible. ``` **Prompt:** ``` I use my laptop at high brightness just 30 minutes before my 23:00 bedtime. What is my risk? ``` **Response:** ``` Your melatonin suppression risk is high, and you may experience significant sleep onset delay. It is highly recommended to use blue light blocking glasses. ``` **Prompt:** ``` I wake up at 07:00 and don't have access to the outdoors. How can I stay alert? ``` **Response:** ``` Your optimal light window is from 07:00 to 07:45. Since you lack outdoor access, a High-LUX Light Box is the recommended light source. ``` ## Capabilities ### Risk Assessment Your agent checks how your screen brightness and timing affect your melatonin levels. ### Schedule Generation Your AI client creates a daily timeline for light exposure and screen cutoff times. ### Mitigation Advice Your agent identifies if you need software filters or physical blue light glasses. ### Morning Planning Your AI client builds a routine to anchor your circadian rhythm every morning. ## Use Cases ### Evening Wind-down You ask your agent for a cutoff time so you know exactly when to stop using your laptop. ### Morning Alertness You use the morning plan to figure out how to get enough light when you can't go outside. ### Device Setup You check if your current screen brightness requires you to buy blue light blocking glasses. ### Sleep Goal Alignment You provide your target wake time to get a full daily light activity schedule. ## Benefits - Calculates specific screen cutoff times based on your bedtime. - Identifies melatonin suppression risks from device usage. - Provides hardware and software mitigation recommendations. - Creates morning light plans to improve alertness. ## How It Works Connect the MCP to your client and start asking about your light habits. 1.
