Connects to live UV and weather data to show when you can synthesize vitamin D at your location. Accounts for your skin type, age, clothing and elevation. Tracks your sun sessions and compares vitamin D seasons across cities.

Example request: "Tell me when I should go outside this week to get enough vitamin D in my city"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Vitamin D to help me. It is a free service with an MCP server at https://getvitamind.app/api/mcp/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- search_city: Find a city in the app's database by name (any of the app's six languages works) and get its coordinates, IANA timezone and elevation — feed those into the other tools.
- get_sun_times: Sunrise, sunset, solar noon, civil dawn/dusk, morning AND evening golden hour, and day length (with day-over-day trend) for a location and date. Handles midnight sun and polar night. Pure sun times — for vitamin D questions use the vitamin_d tools instead.
- get_vitamin_d_window: The solar vitamin D synthesis window for ONE specific day at a location, for a personal profile: when UV is strong enough (index ≥ 3), the best hour, the clear-sky minutes needed to reach the target IU, and (with atTime) the minutes at the specific hour the user plans to go out. 
- get_vitamin_d_year: The WHOLE YEAR of solar vitamin D for a location in a single call. monthsWithSun lists every month with at least one viable day (season edges count as partial months, see byMonth[].viableDays); solidMonths lists months where most days work; exactViableSpan gives the exact season 
- configure_sun_profile: Show the user an interactive form for the four values every other tool assumes — Fitzpatrick skin type, fraction of skin exposed, age and target IU — with the minutes they need updating live. Use this when those values are unknown, when the user wants to change them, or instead o
- get_sun_forecast: The NEXT FEW DAYS of vitamin D sun at a location, using the live Open-Meteo forecast: per day the peak UV, average cloud cover, the synthesis window and the minutes needed, plus bestDay. Use this for any question spanning several days — 'which day this week should I go out', 'wil
- compare_vitamin_d_year: Compare the vitamin D year of 2 to 5 places side by side in ONE call — 'Madrid vs Berlin vs Oslo, where do I actually get winter sun?'. Returns each place's months with sun, exact season span and viable days per year, plus rankedByViableDays. Use this instead of calling get_vitam
- get_current_status: Whether RIGHT NOW is a good moment for vitamin D synthesis at a location, using live Open-Meteo UV/cloud data when reachable (clear-sky model otherwise): current UV index, minutes needed now, and when today's window opens or closes.
- estimate_sun_session: Estimate a sun session's outcome: 'I was (or will be) out N minutes — how much vitamin D did I make?' plus 'how long before I'd burn?' for the profile. Takes a start time (defaults to the day's best hour) and session minutes; returns estimated IU (with the physiological cap), ave
- get_my_profile: The signed-in user's saved Vitamin D profile: skin type, exposed-skin default, age, target IU and their current city. Requires connecting with OAuth (scope profile:read). Call this FIRST for any personal question, then pass its values to the public tools instead of asking the use
- get_my_cities: The signed-in user's current city and favorite cities with coordinates and timezones, ready to feed into the public tools. Requires OAuth (scope profile:read).
- update_my_profile: Save the signed-in user's synthesis profile — skin type, exposed-skin fraction, age and target IU — to their account, so the app and every later call use them. Requires OAuth (scope profile:write). Only these four values are writable; favourites, cities and history are not.
- get_my_history: The signed-in user's sun history from the app's calendar: which recent days had viable sun, which they confirmed going outside, and their current streak. Covers the calendar days from `from` to `to`; records exist only for days the app was open, so a date missing from `records` m
- log_sun_session: Sets a day's answer in the signed-in user's history calendar. Three values: confirmed=true (went out, the default), confirmed=false (had usable sun but stayed in), confirmed=null (clear the answer). Defaults to today. Requires OAuth (scope history:write).
- set_history_location: Records where the signed-in user was over a range of past days, so their history stops assuming. Use it when the user corrects a stretch — get_my_history marks inherited days with `locationAssumed`, and the history calendar offers those stretches for correction. Pass a cityId fro
