Vitamind does not always answer

Over the last week it answered 0.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 15

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

history

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` 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.

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 from search_city, or lat/lon. Changes only the location: whether they went outside that day is untouched. Requires OAuth (scope history:write).

profile

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.

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.

sun

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', 'will it be better tomorrow', 'when's my next chance' — instead of calling get_vitamin_d_window once per date.

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.

vitamin

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. 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_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 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.

cities

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).

city

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.

compare

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_vitamin_d_year once per city: only this tool can draw the years on a shared axis.

configure

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 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.

current

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

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), 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

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).

Vitamind — questions

Answers built from our own checks of this server.

What can Vitamind do?

It exposes 15 tools, read directly from the server on our last check. Among them: compare_vitamin_d_year, configure_sun_profile, estimate_sun_session, get_current_status, get_my_cities, get_my_history and 9 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Vitamind mostly used for?

Its tools cluster around profile, sun and vitamin. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Vitamind working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 184 checks got a reply (0.0%), average response time 89 ms. The bar chart above shows every period we have measured.

The registry lists Vitamind as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Vitamind?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Vitamind need an API key?

No. Vitamind completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 15 of them are readable on this page. This is what we observed, not what the docs claim.

Is Vitamind open source?

We cannot say either way: written in TypeScript, 1 stars on GitHub and 6 open issues, but we could not determine the licence, and without one the code is not open source by default.
