## Tools
- search_hexagrams (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 original IChing.Rocks translation; vocabulary from classic English translations (Wilhelm/Baynes, Legge, Blofeld) may not match literally. Data © IChing.Rocks — attribution is a condition of the license terms: https://iching.rocks/mcp-terms. Endpoint: https://mcp.iching.rocks/mcp
- get_hexagrams (Get Hexagrams (Batch)) - 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. Endpoint: https://mcp.iching.rocks/mcp
- list_hexagrams (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) 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. Endpoint: https://mcp.iching.rocks/mcp
- get_server_info (Get Server Info) - 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. Endpoint: https://mcp.iching.rocks/mcp
- get_reading_context (Get Reading Context) - 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. Endpoint: https://mcp.iching.rocks/mcp
- get_trigram (Get Trigram) - 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. Endpoint: https://mcp.iching.rocks/mcp
- get_all_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. Endpoint: https://mcp.iching.rocks/mcp
- list_trigrams (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. Endpoint: https://mcp.iching.rocks/mcp
- get_hexagram (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 to find hexagrams by text, and get_reading_context for a changing-line reading.
