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.

compatibility

compatibility

Compare two people's charts (synastry) from their birth data. Returns the overall tone (flowing, mixed or charged), whether the Sun elements match, the classic pairings (Venus-Mars, Sun-Moon, Moon-Moon, Venus-Venus), the tightest Moon, Venus, Mars and Sun contacts between the two charts, and a link to the free full comparison on lunonis.com. Counted aspects only: there is no compatibility score. Nothing is stored.

natal

natal_chart

Calculate a real natal (birth) chart from a birth date, optional birth time and a city. Returns the Sun, Moon and rising signs, every planet with sign, degree and house, the five tightest aspects, an element and modality summary, and a link to the free full chart with the wheel on lunonis.com. Calculated in-house with an ephemeris (tropical zodiac, Placidus houses); nothing is stored. If the city name matches several places it returns status "ambiguous_place" with candidates: ask the user which one, then call again with that id as place.

places

search_places

Find birth cities by name. Returns up to 6 candidates { id, name, region, country }, the biggest first. Use it to disambiguate a city, then pass the chosen id as the place of natal_chart or compatibility.

Lunonis Astrology — questions

Answers built from our own checks of this server.

What can Lunonis Astrology do?

It exposes 3 tools, read directly from the server on our last check. Among them: compatibility, natal_chart, search_places. 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 Lunonis Astrology working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 73 of 73 checks got a reply (100.0%), average response time 557 ms. The bar chart above shows every period we have measured.

How do I connect Lunonis Astrology?

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 Lunonis Astrology need an API key?

No. Lunonis Astrology 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 Lunonis Astrology?

It answers our handshake in 557 ms on average, which is faster than 21% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
