|---|---|
| search_hexagrams | Deterministic literal/keyword search over a closed whitelist of hexagram text fields (not semantic). Case-, diacritic-, and traditional/simplified Chinese-insensitive. Optional fields, order, and limit (default 10, max 64). Texts are an... |
| get_hexagrams | Batch hexagram lookup by King Wen numbers (max 16 ids per call). Optional include level: summary, core (default), lines, full. Data © IChing.Rocks — attribution is a condition of the license terms: https://iching.rocks/mcp-terms. |
| list_hexagrams | Compact index of all 64 I Ching hexagrams (id, name, pinyin, characters, essence, trigrams, url). Optional order: kingwen (default), mawangdui, eightpalaces, binary. This is the summary index only; get_hexagram (or get_hexagrams)... |

| get_all_hexagrams | The full 64-hexagram dataset in one call (bulk; stricter rate limit). Optional order: kingwen (default), mawangdui, eightpalaces, binary. Data © IChing.Rocks — attribution is a condition of the license terms: https://iching.rocks/mcp-terms. |
| list_trigrams | All eight trigrams with font, binary, pinyin, symbolic name, english name, element character, and function. Data © IChing.Rocks — attribution is a condition of the license terms: https://iching.rocks/mcp-terms. |
| get_hexagram | One hexagram by King Wen number (1-64). Optional include level: summary, core (default), lines, full. Sibling tools cover the other cases: get_hexagrams for several numbers at once, get_all_hexagrams for the entire set, search_hexagrams... |
| list_sequences | Describes the four canonical hexagram orderings (kingwen, mawangdui, eightpalaces, binary) with their 64-entry sequences. Data © IChing.Rocks — attribution is a condition of the license terms: https://iching.rocks/mcp-terms. |
