This MCP server provides precise calculations for vitamin D production based on solar geometry and human biology. Use calculate_synthesis_time to determine how long you need to be in the sun, get_safe_exposure_limit to avoid sunburn, and optimize_exposure_window to find the best time of day for your specific skin type and location. It also includes evaluate_sun_conditions to assess if current UV levels are suitable for synthesis.

4 tools expose this connector's capabilities to your AI agent.

calculate_synthesis_time

Determines how many minutes of exposure are required to reach a target vitamin D synthesis level

evaluate_sun_conditions

Provides a summary of the current environmental ability to support vitamin D production

get_safe_exposure_limit

Calculates the maximum safe time a user can stay in the sun before hitting a high risk of sunburn

optimize_exposure_window

Finds the ideal time of day to achieve vitamin D synthesis while staying within safe limits

How long do I need to be in the sun to get my vitamin D if the UV index is 5, I am skin type II, and my exposed area is 5000 cm2 at latitude 40?

You will need approximately 15 minutes of exposure to reach your target vitamin D synthesis level under these conditions.

What is my safe sun exposure limit right now with a UV index of 8 and skin type III at latitude 35?

Your safe exposure limit is 12 minutes. The risk level is currently High.

When is the best time to go outside for vitamin D synthesis today at latitude 45 with skin type IV?

The optimal window is between 11:30 AM and 1:00 PM, providing a safe duration of 45 minutes.

The tool uses the Fitzpatrick scale to account for melanin levels. Higher melanin levels require more time to synthesize the same amount of vitamin D.
