Chaldean Numerology
asterwise_get_chaldean_numerology
Reduces a name and birth date through the Chaldean letter-value system and returns name, birth, and combined compound analyses with themes and keywords.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
name | string | yes | Person's full name as commonly written; letters are converted to numerology values. |
date | string | yes | Date in YYYY-MM-DD format. |
response_format | enum: markdown, json | no | Output format: 'markdown' (default) for a readable report, or 'json' for the raw structured payload. |
What it covers
Chaldean assigns letters values one through eight (nine treated as sacred/unassigned in tradition). Response includes data.system 'chaldean', echoed full_name and birth_date, plus three parallel number objects (name, birth, compound) each with raw compound, reduced root, theme, keywords, interpretation. It does not output Pythagorean Life Path blocks (asterwise_get_numerology_profile) or Lo Shu grids.
Workflow
BEFORE: None — standalone.
AFTER: asterwise_get_numerology_profile — compare against Pythagorean cores if needed.
Input
name and date forwarded as-is; no local validation.
Output contract
data.system (string — 'chaldean')
data.full_name (string)
data.birth_date (string)
data.name_number:
raw (int — compound)
reduced (int — root)
theme (string)
keywords[] (string array)
interpretation (string)
data.birth_number — same shape as data.name_number
data.compound_number — same shape; raw combines name and birth
Response format
response_format=json serialises the complete response as indented JSON — use this for programmatic parsing, typed clients, and downstream tool chaining. response_format=markdown renders the same data as a human-readable report. Both modes return identical underlying data — no fields are added, removed, or filtered by either mode.

Errors
INVALID_PARAMS (local — caught before upstream call):
None — all validation is upstream.
INVALID_PARAMS (upstream):
— None — upstream rejection surfaces as MCP INTERNAL_ERROR at the tool layer.
INTERNAL_ERROR:
— Any upstream API failure or timeout → MCP INTERNAL_ERROR
Edge cases:
— Chaldean and Pythagorean numbers disagree by design — never merge blindly.
Do not confuse with
asterwise_get_numerology_profile — Pythagorean Life Path / Expression stack, not Chaldean compounds.
asterwise_get_lo_shu_grid — digit placement magic square, not Chaldean name reduction.
