Connect I Ching Hexagram Engine to ChatGPT and Claude
Set it up once and it works in ChatGPT, Claude, Cursor, and any other client you love. It all runs safely in the background, so you can relax and focus on what really matters. Automate complex hexagram calculations and trigram lookups.
Developed, maintained, and hosted by Vinkius.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.
Your AI does the work. We keep it safe and sound.
No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.
Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

Each Connector runs inside its own sealed environment.
Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.
One switch stops every agent. Instantly.
One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.
Spending limits that pause instead of surprise.
Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.
Three controls, built into the layer your AI connects through.
Curated set · 3 capabilities
We ship only the actions that matter.
01-03
3 capabilities in this set.
Part of 3 available through I Ching Engine.
- 01
Calculate hexagram
This capability computes the full suite of hexagram data based on the line values you provide.
- 02
Get trigram details
This capability retrieves the specific name and composition of a requested trigram.
- 03
Interpret coin toss
This capability converts a sequence of coin toss results into the corresponding numeric line values.
Real work
What teams actually run
Automated Divination
Your agent performs a reading by interpreting coin tosses and calculating the resulting hexagrams.
Mathematical Verification
Use the engine to double check the math of an AI agent's manual interpretation.
Data Processing
Convert long lists of coin toss sequences into structured hexagram data for analysis.
Trigram Lookup
Quickly pull the composition of a trigram to inform an agent's response.
One connector, every AI
I Ching Engine works with the most popular AI clients.
These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Le ChatBuilding your own app? The connector is yours to use.
You don't need a client to put I Ching Engine to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

One URL. Every client.
Activate the Connector, copy your link, and paste it into the client you already use. 3 capabilities arrive ready to run.
Preview access · not provider authentication
The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of I Ching Engine, so you can see the experience inside your AI.
It does not authenticate your account with I Ching Engine. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

- 04
Which AI clients can use this MCP?
Any MCP-compatible client, such as Claude, Cursor, or Windsurf, can use this capability.
- 05
Do I need to provide the line values myself?
You can either provide the line values directly or use the coin toss capability to generate them.
- 06
What are the valid line values?
The valid line values are 6 (Old Yin), 7 (Young Yang), 8 (Young Yin), and 9 (Old Yang).
- 07
How do I use coin tosses?
You can use the interpret_coin_toss capability by providing an array of six 3-character strings representing the results of three coin tosses for each line.
- 08
What is a nuclear hexagram?
A nuclear hexagram is a hidden hexagram derived from the internal lines (2-3-4 and 3-4-5) of the primary hexagram.
