get_all_hexagramsread-only | 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. |
get_hexagramread-only | 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 to find hexagrams by text, and get_reading_context for a changing-line reading. Data © IChing.Rocks — attribution is a condition of the license terms: https://iching.rocks/mcp-terms. |
get_hexagramsread-only | 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. |
get_reading_contextread-only | Deterministic reading context for a primary hexagram (1-64) and 0-6 ascending changing lines. Empty changing_lines returns the primary hexagram only; one or more changing lines add the resulting hexagram, the transition, and the changing-line texts. No divination is performed. Data © IChing.Rocks — attribution is a condition of the license terms: https://iching.rocks/mcp-terms. |
get_server_inforead-only | Build identity of the running iching.rocks MCP server: name, semantic version, git revision, protocol, and canonical MCP endpoint. Identity only — returns no hexagram data. |
get_trigramread-only | One of the eight trigrams by exactly one identifier: binary (e.g. 010), english (e.g. Fire), chinese (pinyin, e.g. Li), symbolic (e.g. Radiance), or element (Chinese character, e.g. 火). This returns a single trigram; list_trigrams returns all eight. Data © IChing.Rocks — attribution is a condition of the license terms: https://iching.rocks/mcp-terms. |
list_hexagramsread-only | 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) returns full detail for a known number, get_all_hexagrams returns the full dataset in one call, and search_hexagrams finds hexagrams by text. Data © IChing.Rocks — attribution is a condition of the license terms: https://iching.rocks/mcp-terms. |
list_sequencesread-only | 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. |
list_trigramsread-only | 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. |
search_hexagramsread-only | 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 original IChing.Rocks translation; vocabulary from classic English translations (Wilhelm/Baynes, Legge, Blofeld) may not match literally.
