This MCP gives your AI client the math it needs to build a functional sleep schedule. If you know when you need to wake up and how much rest you require, your agent can use the get_bedtime tool to work backward and find your ideal lights-out time. It even handles the logic for when your bedtime falls on the previous night. Beyond just calculating times, this MCP helps you evaluate your habits. You can ask your agent to check if a specific amount of sleep is sufficient using the get_sleep_efficiency_recommendation tool. It also cleans up the output, using format_display_time to turn 24-hour timestamps into something easy to read. If you're building a routine, the validate_time_format tool ensures your inputs are correct before any calculations happen. It's a simple way to bridge the gap between your daily schedule and your physical need for rest. ## Tools ### get_sleep_efficiency_recommendation This tool provides a qualitative assessment of how much sleep you're getting.
