Endpoint Security80
Transport & Reachability100
Schema Quality & AI Usability82
  • AI-judged instruction clarity (excellent).Pass

  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
  • Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Install

How do I install the I Ching MCP Server by RoxyAPI server?

I Ching MCP Server by RoxyAPI is a hosted endpoint at https://roxyapi.com/mcp/iching, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 9 exposed · ~2,225 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
get_iching_cast ~279

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.

get_iching_hexagrams ~262

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.

get_iching_hexagrams_lookup ~251

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).

Use this to display detailed hexagram information after casting or for educational reference.

get_iching_trigrams ~222

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.

post_iching_daily ~293

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.

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.
