## MCP tools (1)

### `cast_chart` (~421 tokens)

Cast destiny charts (BaZi / Zi Wei / Western astrology)

Cast up to three deterministic destiny charts from one birth: BaZi (Four Pillars, with True Solar Time correction), Zi Wei Dou Shu (Purple Star Astrology), and a Western natal chart (tropical zodiac, Placidus houses). Free and anonymous — no account, nothing stored. Input is either a one-line `text` birth description, or structured fields (year/month/day/hour/minute + gender + longitude/latitude + timeZoneId). Returns structured JSON per system: field names in English; traditional terms (stems & branches, palace and star names) in their native Chinese characters — translate them for the user as needed. The chart data is computed, not AI-generated; interpretation is up to you. Full reading tools at https://fatenava.com?utm_source=fatenava-mcp&utm_medium=agent

Input parameters:

- `birthTimeKnown` (boolean): Set false when the exact birth time is unknown — BaZi still returns three pillars; hour-dependent parts are omitted honestly
- `day` (integer)
- `gender` (string): Required with structured input
- `hour` (integer): Birth hour 0-23; pass with birthTimeKnown=false if unknown
- `latitude` (number)
- `longitude` (number): Birthplace longitude (structured input); used for True Solar Time correction
- `minute` (integer)
- `month` (integer)
- `systems` (array): Which chart systems to return: "bazi", "ziwei", "astro". Default: all three.
- `text` (string): One-line birth description: date, time (or omit if unknown), birthplace, gender. Example: "1995-08-10 12:00 Taipei female". City names in English, Chinese, Japanese or Korean are accepted. Use EITHER…
- `timeZoneId` (string): IANA timezone of the birthplace, e.g. "Asia/Taipei" (structured input)
- `year` (integer): Birth year (structured input)
