Rahu-Ketu Axis Transit

get_rahu_ketu_axis_transit

T13, the scale of months: the transit nodes over the natal positions of the event's fruitful significators. Returns '{ event, technique, fruitfulPlanets, hits[], summary, eventResolution }'. The same block 'get_transit_timing_panel' returns as 'rahuKetuAxis'.

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.
