Nothing serious here today

Today is the operative word: we check Moon & Star Map every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 3

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

generate

generate_moon_poster

Use this when the user wants a printable moon phase poster: the moon on one special date, two dates side by side ("our moons" couple print), or a lunar calendar of a whole year. Computes the real phases and returns a preview plus vector PDFs (12x18 in, 18x24 in, A3, Letter, A4) and SVG. Does not sell or ship prints. Do not use for a quick phase answer without a poster; that is find_moon_phase.

generate_star_map

Use this when the user wants a star map or night sky poster for a date and place: the sky over a city on a birthday, wedding, anniversary or the night they met, or the sky tonight. Computes the real positions of about 2,900 stars, constellation lines and the Moon for the city's local time (time zones and DST handled) and returns a preview plus vector poster PDFs (12x18 in, 18x24 in, A3, Letter, A4) and SVG. Takes a city name, not coordinates. Does not draw planets and is not for navigation or telescope pointing.

moon

find_moon_phase

Use this when the user asks what the moon looked like on a date (birthday, wedding, first date), the moon phase today or tonight, whether two people's birthday moons complete each other ("our moons make a full moon"), or wants a moon phase calendar for a month. Returns phase name, illumination %, moon age, waxing/waning, exact phase times and the next full and new moon, computed with astronomical algorithms. Does not give astrology readings, tides or moonrise times. Do not use for planets or eclipses.

Moon & Star Map — questions

Answers built from our own checks of this server.

What can Moon & Star Map do?

It exposes 3 tools, read directly from the server on our last check. Among them: find_moon_phase, generate_moon_poster, generate_star_map. 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 →

Is Moon & Star Map working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 360 ms. The bar chart above shows every period we have measured.

How do I connect Moon & Star Map?

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 Moon & Star Map need an API key?

No. Moon & Star Map completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Moon & Star Map?

It answers our handshake in 360 ms on average, which is faster than 38% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
