Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
sun_timesSunrise, sunset, solar noon and day length at a place on a day (today by default), with how much longer or shorter the day is than the day before, civil, nautical and astronomical twilight, and the golden and blue hours for photos. Local clock time, to the minute.
sun_calendarSunrise, sunset and day length for every day of a month at a place, with the change of the day length from day to day; the link opens the same calendar to print on one A4 page.
moon_timesMoonrise and moonset at a place on a day (today by default), the moon's phase and lit part, a new or full moon or quarter that day, and the next new and full moon.
moon_phasesThe new moons, first quarters, full moons and last quarters between two dates (two years at most; from today for 60 days by default), to the minute in a time zone (Polish time by default).
clock_changeWhen the clocks change in Poland in a year (this year by default): the dates, which way and at what time, and the next change from today.
solsticeThe December and June solstices of a year (this year by default) to the minute, Polish time; with a place, also its shortest and longest day, the earliest sunset and the latest sunrise of the winter.
find_cityThe site's places whose name starts with the text (Polish or English names, with or without Polish letters): 258 places (Polish cities, places for trips and a few cities abroad), with coordinates, time zone and page.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
