## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 9 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 59/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2622 tokens (~291/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability check failed: schema churn in the 8 days we've observed: 0 tool removals, 1 breaking changes, 0 auth/transport breaks, 0 additions.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (9)

### `post_iching_daily` (~337 tokens)

Get daily I-Ching hexagram

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.

Input parameters:

- `compact` (boolean): Set true to receive the exact same data in a token-optimized shape that is cheaper for you to read: whitespace is stripped and every array of same-shaped objects is encoded columnar as {"__cols":[fie…
- `date` (string): Date for the reading in YYYY-MM-DD format. Defaults to today (UTC). Useful for viewing past daily readings or pre-generating future ones.
- `lang` (string): Response language (ISO 639-1). Supported: en, tr, de, es, hi, pt, fr, ru. Defaults to en. Languages without translations yet return English.
- `seed` (string): Optional seed for reproducible readings. Same seed + same date = same hexagram every time. Pass any unique identifier (userId, email hash, session token). Omit for anonymous daily readings.

### `post_iching_daily_cast` (~330 tokens)

Cast daily I-Ching reading with changing lines

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.

Input parameters:

- `compact` (boolean): Set true to receive the exact same data in a token-optimized shape that is cheaper for you to read: whitespace is stripped and every array of same-shaped objects is encoded columnar as {"__cols":[fie…
- `date` (string): Date for the reading in YYYY-MM-DD format. Defaults to today (UTC). Useful for viewing past daily readings or pre-generating future ones.
- `lang` (string): Response language (ISO 639-1). Supported: en, tr, de, es, hi, pt, fr, ru. Defaults to en. Languages without translations yet return English.
- `seed` (string): Optional seed for reproducible readings. Same seed + same date = same hexagram every time. Pass any unique identifier (userId, email hash, session token). Omit for anonymous daily readings.

### `get_iching_hexagrams` (~306 tokens)

List all 64 hexagrams

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.

Input parameters:

- `compact` (boolean): Set true to receive the exact same data in a token-optimized shape that is cheaper for you to read: whitespace is stripped and every array of same-shaped objects is encoded columnar as {"__cols":[fie…
- `lang` (string): Response language (ISO 639-1). Supported: en, tr, de, es, hi, pt, fr, ru. Defaults to en. Languages without translations yet return English.
- `limit` (integer): Maximum items to return per page. Range: 1-64, default 20.
- `offset` (integer|null): Number of items to skip for pagination. Default 0.

### `get_iching_hexagrams_random` (~225 tokens)

Get a random hexagram

Receive a random I-Ching hexagram with full interpretation. Perfect for daily oracle features, meditation prompts, or exploring the Book of Changes. Returns complete hexagram data including judgment, image, interpretations for love/career/decisions, and all six changing line meanings.

Input parameters:

- `compact` (boolean): Set true to receive the exact same data in a token-optimized shape that is cheaper for you to read: whitespace is stripped and every array of same-shaped objects is encoded columnar as {"__cols":[fie…
- `lang` (string): Response language (ISO 639-1). Supported: en, tr, de, es, hi, pt, fr, ru. Defaults to en. Languages without translations yet return English.

### `get_iching_hexagrams_lookup` (~295 tokens)

Lookup hexagram by line pattern

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).

Input parameters:

- `compact` (boolean): Set true to receive the exact same data in a token-optimized shape that is cheaper for you to read: whitespace is stripped and every array of same-shaped objects is encoded columnar as {"__cols":[fie…
- `lang` (string): Response language (ISO 639-1). Supported: en, tr, de, es, hi, pt, fr, ru. Defaults to en. Languages without translations yet return English.
- `lines` (string, required): Six-digit binary pattern (0=yin/broken, 1=yang/solid) from bottom to top.

### `get_iching_hexagrams_number` (~261 tokens)

Get hexagram by number

Retrieve complete I-Ching hexagram details by King Wen sequence number (1-64). Returns the full hexagram with Chinese name, English translation, judgment text, image text, modern interpretations for general situations, love, career, and decision-making, plus all six changing line meanings. Use this to display detailed hexagram information after casting or for educational reference.

Input parameters:

- `compact` (boolean): Set true to receive the exact same data in a token-optimized shape that is cheaper for you to read: whitespace is stripped and every array of same-shaped objects is encoded columnar as {"__cols":[fie…
- `lang` (string): Response language (ISO 639-1). Supported: en, tr, de, es, hi, pt, fr, ru. Defaults to en. Languages without translations yet return English.
- `number` (number, required): Hexagram number in King Wen sequence (1-64).

### `get_iching_cast` (~323 tokens)

Cast an I-Ching reading

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.

Input parameters:

- `compact` (boolean): Set true to receive the exact same data in a token-optimized shape that is cheaper for you to read: whitespace is stripped and every array of same-shaped objects is encoded columnar as {"__cols":[fie…
- `lang` (string): Response language (ISO 639-1). Supported: en, tr, de, es, hi, pt, fr, ru. Defaults to en. Languages without translations yet return English.
- `seed` (string): Optional seed for reproducible castings. Same seed = same casting every time. Pass any unique identifier (userId, session token, question hash). Omit for random casting.

### `get_iching_trigrams` (~267 tokens)

List all 8 trigrams

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.

Input parameters:

- `compact` (boolean): Set true to receive the exact same data in a token-optimized shape that is cheaper for you to read: whitespace is stripped and every array of same-shaped objects is encoded columnar as {"__cols":[fie…
- `lang` (string): Response language (ISO 639-1). Supported: en, tr, de, es, hi, pt, fr, ru. Defaults to en. Languages without translations yet return English.

### `get_iching_trigrams_id` (~278 tokens)

Get trigram by number or name

Retrieve a specific I-Ching trigram by its number (1-8) or English name (Heaven, Earth, Thunder, Wind, Water, Fire, Mountain, Lake). Returns complete trigram information including Chinese name, pinyin, element associations, core attributes, and symbolic meaning. Use this to understand the component trigrams of any hexagram.

Input parameters:

- `compact` (boolean): Set true to receive the exact same data in a token-optimized shape that is cheaper for you to read: whitespace is stripped and every array of same-shaped objects is encoded columnar as {"__cols":[fie…
- `id` (string, required): Trigram number (1-8) or English name (Heaven, Earth, Thunder, Wind, Water, Fire, Mountain, Lake).
- `lang` (string): Response language (ISO 639-1). Supported: en, tr, de, es, hi, pt, fr, ru. Defaults to en. Languages without translations yet return English.
