Graha Yuddha (Planetary War)

get_graha_yuddha

[Vedic Parashari] Planetary war detection among the 5 tara grahas (Mercury, Mars, Venus, Jupiter, Saturn), the classical doctrine of Varahamihira's Brihat Samhita ch.17, not KP: the KP Readers state no planetary-war rule, so a war is a cross-system note and moves no KP verdict. Any pair within 1° is in war; the victor is the planet stationed further north (apparent latitude), with Venus taking an equal-latitude tie on brightness, and 'winnerReason' says which. 'alternativeVerdicts' reports what the later lower-longitude shortcut and a dignity ranking would have decided; neither is the Brihat Samhita criterion. Returns active wars, winner/loser, separation arc, severity (CLOSE ≤0.5° / MODERATE ≤1°), and the loser's suppressed significations (the Parashari reading). Sun, Moon, Rahu, Ketu do not participate.

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.
