  What this check looks for
Description, as the server wrote it
Generate an authentic I-Ching reading using the traditional three-coin casting method. Each of the six lines is determined by virtually tossing three coins, producing values 6-9 where 6 (old yin) and 9 (old yang) are changing lines. Returns the primary hexagram with full interpretation, the line values showing which lines are changing, and if any lines change, the resulting hexagram that the primary transforms into. Optionally provide a seed for reproducible castings. Perfect for divination apps, oracle features, and decision-making tools.

  What this check looks for
Description, as the server wrote it
Receive a daily I-Ching hexagram for guidance and reflection. This endpoint uses seeded randomness to ensure the same seed gets the same hexagram on the same day, perfect for "Hexagram of the Day" features in oracle apps, meditation platforms, and daily wisdom tools. Returns the hexagram with judgment, image, and interpretations for love, career, decisions, and practical advice based on ancient Chinese wisdom from the Book of Changes.

  What this check looks for
Description, as the server wrote it
Cast a complete daily I-Ching reading using the traditional three-coin method with seeded randomness. Unlike the simple daily hexagram, this provides the full casting experience with line values (6-9), changing line positions, and the resulting hexagram if transformation occurs. Same seed + same date = same casting result. Perfect for I-Ching divination apps requiring authentic oracle experience with daily consistency.

- The name "get_iching_hexagrams" says "get": a word for reading.
Description, as the server wrote it
Browse all 64 I-Ching hexagrams from the Book of Changes with their Chinese names, English translations, and trigram compositions. The hexagrams are ordered by the traditional King Wen sequence used in I-Ching divination for 3,000 years. Each hexagram represents a unique life situation combining two trigrams (Heaven, Earth, Thunder, Wind, Water, Fire, Mountain, Lake) into profound wisdom for decision-making and self-understanding.

Why it is in this group
- The name "get_iching_hexagrams_lookup" says "get": a word for reading.
Description, as the server wrote it
Find an I-Ching hexagram by its binary line pattern. Provide 6 digits (0 or 1) representing broken (yin) and solid (yang) lines from bottom to top. Use this for custom divination interfaces where users input their own line configurations, or to find hexagrams matching specific trigram combinations. Example: "111111" returns Hexagram 1 (The Creative), "000000" returns Hexagram 2 (The Receptive).

- The name "get_iching_trigrams" says "get": a word for reading.
Description, as the server wrote it
Retrieve all 8 I-Ching trigrams (bagua), the fundamental building blocks of hexagrams. Each trigram consists of three lines and represents a primal force of nature: Heaven (Qian), Earth (Kun), Thunder (Zhen), Wind (Xun), Water (Kan), Fire (Li), Mountain (Gen), and Lake (Dui). Understanding trigrams is essential for interpreting hexagram meanings, as each hexagram combines an upper and lower trigram.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

3 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
