Example request: "What time is sunset in Kraków today, and when is the next full moon?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Słońce to help me. It is a free service with an MCP server at https://slonce.info.pl/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:
- sun_times: Sunrise, 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_calendar: Sunrise, 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_phases: The 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_change: When 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.
- solstice: The 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.
