What this server can do
15 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
compare_vitamin_d_year(age, places, skinType, targetIU, exposedSkinFraction)- 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_vitamin_d_year once per city: only this tool can draw the years on a shared axis. Required: places.
configure_sun_profile(age, lat, lon, skinType, targetIU, timezone, placeName, exposedSkinFraction)- 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 of asking for them one at a time in conversation. Whatever the user picks comes back into the conversation; pass those values explicitly to the other tools afterwards.
estimate_sun_session(age, lat, lon, date, minutes, skinType, timezone, startTime, elevationM, exposedSkinFraction)- 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), average UV and clear-sky minutes-to-sunburn. Use for any 'how much did I get / can I get in X minutes' or 'how long without burning' question. Required: lat, lon, minutes.
get_current_status(age, lat, lon, skinType, targetIU, timezone, elevationM, exposedSkinFraction)- 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. Required: lat, lon.
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).
get_my_history(days)- 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` means nothing was measured, not that the sun was insufficient. Requires OAuth (scope history:read). Renders as a calendar the user can tap to confirm a day.
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 user.
get_sun_forecast(age, lat, lon, days, skinType, targetIU, timezone, elevationM, exposedSkinFraction)- 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', 'will it be better tomorrow', 'when's my next chance' — instead of calling get_vitamin_d_window once per date. Required: lat, lon.
get_sun_times(lat, lon, date, timezone)- 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. Required: lat, lon.
get_vitamin_d_window(age, lat, lon, date, atTime, skinType, targetIU, timezone, elevationM, exposedSkinFraction)- 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. Returns synthesisPossible=false when the sun never gets high enough that day. Only for single-day questions — for months, seasons or 'when during the year', call get_vitamin_d_year instead of calling this once per date. Required: lat, lon.
get_vitamin_d_year(age, lat, lon, skinType, targetIU, timezone, placeName, elevationM, exposedSkinFraction)- 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 boundaries; summary carries per-year aggregates for comparing places. Use this for any question about months, seasons, winter/summer or 'when during the year can I…' — never probe individual dates with get_vitamin_d_window for that. Required: lat, lon.
log_sun_session(date, minutes, confirmed)- 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).
search_city(query)- 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. Required: query.
set_history_location(to, lat, lon, from, cityId)- 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 from search_city, or lat/lon. Changes only the location: whether they went outside that day is untouched. Requires OAuth (scope history:write). Required: from, to.
update_my_profile(age, skinType, targetIU, exposedSkinFraction)- 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.

Signals
These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
