Arudha Lagna (AL), Public Image [Jaimini]

get_arudha_lagna

[Jaimini adjunct] Arudha Lagna, the Pada of the 1st house, representing public image / how the world perceives the native. Calculated by counting from lagna to lagna lord, then same count again from the lord. Returns AL sign, lord, occupants, the planets aspecting it by Jaimini rashi drishti (sign aspects sign, not Parashari graha drishti) with the three aspecting signs themselves, and interpretation. The disputed parts ship as stated readings, none picked: 'exceptionVariants' where the 1st/7th exception applies (the shipped 10th from where the pada fell, BPHS ch. 29; the 10th from the house, unsourced; no exception, K. N. Rao and B. S. Rao), and for a Scorpio or Aquarius lagna 'coLordFork' (the pada counted to Ketu or Rahu, and P.V.R. Narasimha Rao's stronger co-lord by his stated rules). Foundational Jaimini concept; B2B fit for personal-branding apps.

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.
