Cuspal Interlink Strength Matrix

get_interlink_strength_matrix

Computes a 12×12 cuspal interlink strength matrix. Each cell scores how strongly cusp i's {sub, star, sign} lords appear among cusp j's {occupant, owner, star-of-occupant, star-of-owner}. Weights: sub-lord match = 3, star-lord = 2, sign-lord = 1. Per-cell max = 24. Returns '{ matrix, flatTopLinks, averageRatio, densestHouse, methodologyNote, summary, pagination, pageNote }'. **'matrix' is paged by row**, one row per cusp with all 12 of its cells intact, so a page is whole cusps and never half a row. 'flatTopLinks' (the 24 strongest links overall), 'densestHouse' and 'averageRatio' repeat on every page and are usually the answer on their own, so page into the full matrix only when you need a specific cusp pair the top links do not cover.

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.
