Advanced CSL Analysis

get_csl_advanced

Advanced CSL analysis: multi-cusp convergence (all related cusps checked independently), cuspal interlink event scoring, 6-level sublord constellation mapping (sign→star→sub→sub's sign→sub's star→sub's sub), and cusp degree sensitivity detection (boundary conditions within 10 arc-minutes). Essential for thorough promise analysis.

Parameters

Name	Type	Required	Description
birth_datetime	string	Yes	Birth date and time in ISO 8601 format (e.g., "1990-05-15T14:30:00").
latitude	number	Yes	Birth location latitude. Range: -90 to 90.
longitude	number	Yes	Birth location longitude. Range: -180 to 180.
utc_offset_minutes	number	Yes	UTC offset in minutes (e.g., 330 for IST, -300 for EST).
ayanamsa	enum: kp \| lahiri \| raman \| true_chitra	No	Ayanamsa system. Defaults to kp.
event	event name	No	Event for CSL analysis (default: Marriage). Ignored if house_group is provided.
house_group	array<house number (1-12)>	No	Custom house group override (e.g., [5,2,11] for speculation)
sensitivity_threshold_arcmin	number	No	Arc-minute threshold for cusp sensitivity (default: 10)

Engine endpoint

This tool delegates to the kp-engine endpoint:

POST /v1/kp/csl-analysis/advanced

The engine is a private internal service. All public access flows through the MCP server, which handles auth, rate limiting, and response compaction.

Birth data

This tool requires birth data. If you have already called set_birth_profile in the same conversation, the MCP server injects those fields automatically and you can omit them from the call.
