Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a file path from a variable src/portrait.ts:106, src/server.ts:183

const FONTS = ["CormorantGaramond-500.ttf", "CormorantGaramond-600.ttf", "Inter-400.ttf", "DejaVuSans.ttf"].map((f) => path.join(fontDir, f));

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 6

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

birth

get_birth_chart

Computes a real birth chart from astronomical positions (tropical zodiac): Sun to Pluto with sign, degree and retrograde flag, major aspects with orbs, and a short character-focused interpretation. Ascendant, Midheaven and Whole Sign houses only when birth time and place are both given. Without a time the Moon is flagged as approximate. No predictions, nothing stored.

celebrities

list_celebrities

Lists the famous people you can compare charts with in compare_charts (about 1000 most-followed real people on X, birth dates from Wikidata cross-checked with Grokipedia). Optional search query (name, handle or description such as 'singer'); returns up to 25, most followed first. Most are date-only.

christmas

create_christmas_star_card

Creates a festive Christmas card (text plus SVG image) about someone, from their birth date and optional first name: sun sign and life path number, described as character, not prediction. The card text talks about the recipient in the third person (by name, or neutrally without a name). No personal data stored.

compare

compare_charts

Compares two birth charts (synastry): the closest aspects between person A's and person B's planets, with orbs and a short, balanced summary. Birth times and places are optional. Instead of person_b you can pass `celebrity` (name or X handle, see list_celebrities) for a playful star match with a score and a share text for X. No predictions, nothing stored.

sun

get_sun_sign_reading

Returns a short, free reading based only on a birth date: sun sign (simple date table) and Pythagorean life path number, with a few sentences about character, written in the third person by default. No predictions, no personal data stored.

transits

get_transits

Shows where the planets are now (or on a given UTC date) and which major transits they make to a person's birth chart, with orbs and exact dates, for one day or a 7-day week. Short reflective interpretation, no predictions, nothing stored.

Stellara — questions

Answers built from our own checks of this server.

What can Stellara do?

It exposes 6 tools, read directly from the server on our last check. Among them: compare_charts, create_christmas_star_card, get_birth_chart, get_sun_sign_reading, get_transits, list_celebrities. 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 Stellara 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 228 ms. The bar chart above shows every period we have measured.

How do I connect Stellara?

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 Stellara need an API key?

No. Stellara completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Stellara?

It answers our handshake in 228 ms on average, which is faster than 72% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Stellara open source?

The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at mcp.mystellara.com, which runs on its operator's own terms.
