Tools & capabilities

Saju MCP tools 4

  • saju_calculateCompute the Korean Four Pillars of Destiny (사주팔자 / Bazi) from a solar birthdate. Returns the year/month/day/hour pillars (heavenly stem + earthly branch, with hanja), the five-element distribution (wood/fire/earth/metal/water), the Day Master, and the zodiac animal.
  • saju_interpretFull Saju interpretation from a solar birthdate: the Four Pillars plus Ten Gods (십신), hidden stems, life stages, interactions, Yongshin (용신 / useful god), Daeun (대운 / luck pillars), and human-readable summaries in the requested language.
  • saju_compatibilityScore two-person compatibility (궁합) from 0–100 based on both people's Saju. Returns the overall score and a breakdown (element balance, Day Master relation, branch harmony, branch clash) plus each person's Day Master and zodiac.
  • saju_dailyDaily fortune snapshot (0–100 score + advice) for a given Day Master and date. Provide the Day Master either as a Korean stem character (갑, 을, 병, 정, 무, 기, 경, 신, 임, 계) or an English alias (e.g. wood_yang, water_yin). The Day Master comes from a prior saju_calculate / saju_interpret call (day_master.stem).
