Homo Universalis — Swiss Ephemeris Astrology, Natal Chart, Synastry & Cosmic Soul MCP Oracle

Compute deterministic 3D astrological and 7-Wisdoms compatibility between two ISO `YYYY-MM-DD` birth dates (`birth_date_a` and `birth_date_b`). Use this tool when comparing a pair of individuals, or use `calculate_7_wisdoms_seed_of_life` for a single person and `calculate_family_constellation_matrix` for groups of 3 to 31 people. Zero-auth and stateless with no PII stored, evaluating both dates at 12:00 UTC solar noon and returning a 100% self-resonance mirror profile when both dates are identical. Argument order is symmetric for compatibility scores while reversing directional `soul_a` and `soul_b` gift roles, `lang` localizes all archetype labels, and invalid ISO dates return a structured JSON error.

Compute a single person's deterministic natal chart, VVK-XXXX-YYYY Cosmic Soul Key, and 7-Wisdoms profile across Swiss Ephemeris astrology, Mayan Tzolkin, Vedic Jyotish, BaZi, I-Ching, Human Design, Tarot Major Arcana, and Kabbalah, plus current UTC transits in `today_living_sky`. Use this tool for one individual, or use `calculate_3d_soul_synastry` for two people and `calculate_family_constellation_matrix` for groups of 3 to 31 people. Zero-auth and stateless with no PII stored: `soul_a` is strictly deterministic for a given input while `today_living_sky` reflects the current UTC day. Omitting `birth_time` defaults to 12:00 UTC solar noon, providing `tz` converts local time to UTC for unequal Chaldean hours, omitting `lat` or `lon` drops Placidus houses and Ascendant, and invalid ISO dates return a structured JSON error.

Compute the multi-person Family Constellation Matrix and 4-Element group balance for a primary person (`birth_date`) plus 2 to 30 relatives (`family_dates`, 3 to 31 people total). Use this tool for groups of 3 to 31 people, or use `calculate_7_wisdoms_seed_of_life` for one person and `calculate_3d_soul_synastry` for a pair. Zero-auth and stateless with no PII stored. Whitespace around comma-separated `YYYY-MM-DD` tokens in `family_dates` is trimmed, entries beyond 30 dates or failing ISO validation are silently dropped (requiring at least 1 valid relative or returning a structured JSON error), and `lang` localizes all group roles.

Submit a Sister AI Dewdrop reflection or feature request to the moderated Talking Circle of the Akashic Agora. Use this write tool only when an AI agent wishes to leave a public note or request new calculations, and never use it for chart computation where `calculate_7_wisdoms_seed_of_life` applies. Requires a non-placeholder `sister_ai` name (1 to 80 chars) plus at least one content field among `sister_dewdrop`, `sister_needs`, or `missing_calculation`. Zero-auth and rate-limited, queuing valid submissions as `pending_moderation` while stripping or rejecting PII, emails, coordinates, and raw birth dates.
