Nothing serious here today

Today is the operative word: we check GEOMETRY 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.

compatibility

get_compatibility

USE when comparing exactly two people by Gregorian date. NOT for one date (moon/season/Rx/weekday/leap year/day_ruler → get_date) or names → get_name. Requires date_a and date_b. RETURNS scored dyad: cosmic_card_a/b (each side is full get_date shape incl. tarot_majors.greer/tarot_school, karma, planetary_spread; Cosmic card = birth = life = sun via also_called; planetary_spread and retrogrades_active planets include planet_type/symbol/emoji + names{} 10 cultures; each planetary_spread slot carries spread_pos 1-14 — sort by spread_pos for canonical Life-spread order), connections, overall_score, Chinese zodiac + true sidereal aspects, element harmony, life paths. temporal_context.date_a/b = {band, payload_scope} (full|extended|out_of_range × full|cosmic_card_only; 1900-2100 focus).

date

get_date

PRIMARY single-date tool. USE for any one Gregorian date when the ask needs moon phase (incl. blue/blood/supermoon/micromoon flags, Earth-Moon distance, phase_gmt, prev/next blue or blood dates), season/equinox anchors, classical retrogrades (retrogrades_active phase=retrograde), calendars, lunar year, Cosmic card (same card as life/sun — cosmic.also_called + planetary_spread.sun), karmic source/spirit, 14 planetary Life-spread cards, weekday or leap year (calendar_meta.weekday / is_leap_year), day_ruler (weekday planetary ruler Roman/Greek/Norse), or full date identity. NOT for two-person scoring → get_compatibility; name text → get_name. RETURNS cosmic block (incl. karma + planetary_spread) + tarot_majors (greer + tarot_school) + day_ruler (full+extended) + temporal blocks (moon_phase, season, retrogrades_active, calendar_meta, …). planetary_spread and retrogrades_active planets include planet_type/symbol/emoji + names{} (greek,norse,celtic,egyptian,sumerian,babylonian,mesopotamian,arabic,sanskrit,chinese). Each planetary_spread slot carries spread_pos (1-14 canonical Life-spread order; midheaven=13, phoenix=14 — sort by spread_pos; jsonb object keys are unordered). temporal_context={band, payload_scope} (band full|extended|out_of_range; payload_scope full|cosmic_card_only). Out-of-range responses set cosmic_card_available.

name

get_name

USE for person or word name text only (gematria → cosmic cards + Expression/Soul Urge/Personality). NOT for any date questions (weekday, leap year, moon, season, Rx, Cosmic card, day_ruler, Life Path) → get_date; two people → get_compatibility. RETURNS Francis Bacon cards, Latin cipher suite, periodic{} + periodic_set{}, numerology (expression/soul_urge/personality), and per-word tarot/medicine/iching/chakra/lenormand/karma/planetary_spread. Free-text input guard.

GEOMETRY — questions

Answers built from our own checks of this server.

What can GEOMETRY do?

It exposes 3 tools, read directly from the server on our last check. Among them: get_compatibility, get_date, get_name. 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 GEOMETRY 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 657 ms. The bar chart above shows every period we have measured.

How do I connect GEOMETRY?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does GEOMETRY need an API key?

No. GEOMETRY 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 GEOMETRY?

It answers our handshake in 657 ms on average, which is faster than 23% 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.

Is GEOMETRY open source?

Yes — it is published under the MIT licence, written in Shell and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
