set_history_locationRecords where the signed-in user was over a range of past days, so their history stops assuming.No findings
Why it is in this group
- The name "set_history_location" says "set": a word for a change.
- The input addresses people (input.to): what it sends cannot be taken back.
Description, as the server wrote it
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).

Changes things 3Creates or changes something that can be changed back.Claude Code: ask

estimate_sun_sessionEstimate 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.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
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.
log_sun_sessionSets a day's answer in the signed-in user's history calendar.No findings
Why it is in this group
- The name "log_sun_session" says "log": a word for reading.
- The description's first verb is "set": a word for a change.
Description, as the server wrote it
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).
update_my_profileSave 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.No findings
Why it is in this group
- The name "update_my_profile" says "update": a word for a change.
Description, as the server wrote it
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.

compare_vitamin_d_yearCompare 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?'.No findings
Why it is in this group
- The name "compare_vitamin_d_year" says "compare": a word for reading.
Description, as the server wrote it
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.

  What this check looks for
Description, as the server wrote it
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.

Why it is in this group
- The name "get_current_status" says "get": a word for reading.
Description, as the server wrote it
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.
get_my_citiesThe signed-in user's current city and favorite cities with coordinates and timezones, ready to feed into the public tools.No findings
Why it is in this group
- The name "get_my_cities" says "get": a word for reading.
Description, as the server wrote it
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_historyThe 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.No findings
Why it is in this group
- The name "get_my_history" says "get": a word for reading.
Description, as the server wrote it
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_profileThe signed-in user's saved Vitamin D profile: skin type, exposed-skin default, age, target IU and their current city.No findings
Why it is in this group
- The name "get_my_profile" says "get": a word for reading.
Description, as the server wrote it
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.

Why it is in this group
- The name "get_sun_forecast" says "get": a word for reading.
Description, as the server wrote it
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.
get_sun_timesSunrise, sunset, solar noon, civil dawn/dusk, morning AND evening golden hour, and day length (with day-over-day trend) for a location and date.1 finding

  What this check looks for
Description, as the server wrote it
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.

Why it is in this group
- The name "get_vitamin_d_window" says "get": a word for reading.
Description, as the server wrote it
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.
get_vitamin_d_yearThe WHOLE YEAR of solar vitamin D for a location in a single call.No findings
Why it is in this group
- The name "get_vitamin_d_year" says "get": a word for reading.
Description, as the server wrote it
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.
search_cityFind 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.No findings
Why it is in this group
- The name "search_city" says "search": a word for reading.
Description, as the server wrote it
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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
