## Tools (as reported by the server, not verified)

- `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 Engl
- `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 \(or get\_hexagrams\) returns full detail for a known number, get\_all\_hexagrams returns the
- `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.
- `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 —
- `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 o
- `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 to find hexagrams by text, and get\_reading\_context for a changi
- `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.
