Jaimini Chara Karakas (Atmakaraka → Darakaraka)
get_chara_karakas
[Jaimini adjunct] Chara karakas ranked by exact sidereal longitude within the sign (minutes, then seconds, decide): Atmakaraka (highest, soul) → Amatyakaraka (career) → Bhratri (siblings) → Matri (mother) → [Pitri (father), eight scheme only] → Putra (children) → Gnati (obstacles) → Darakaraka (lowest, spouse). Seven or eight is a live dispute the sutra itself leaves open, so BOTH lists are always returned ('sevenScheme', 'eightScheme' with Rahu at 30 − degree) with 'schemesDisagreeOn' naming the offices that change; 'karaka_scheme' picks which one fills 'karakas' (default seven, Sun to Saturn, no node). A tie is reported at the arc-minute (kala), never the whole degree, and 'tieReadings' carries each source's rule for it (seconds decide; Rahu fills the merged office; same-longitude planets share an office), none picked. Each karaka's 'wholeSignHouse' is the Jaimini house (whole sign from the lagna); 'house' is the KP Placidus bhava, kept for continuity. Used for soul-purpose / career-coaching B2B.

}Birth data
This tool requires birth data on every call. The MCP server is stateless, so calling set_birth_profile first validates the data and returns the reading plan, but it does not store anything. Repeat the same five fields here.
