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.

V8 Isolate01

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.

Kill Switch02

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.

FinOps per User03

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.

Capability set01 / 01

01-03

3 capabilities in this set.

Part of 3 available through Mahjong Scoring Engine.

  1. 01

    Calculate final score

    This capability converts Han and Fu values into the final score and specific payment breakdown. It handles the math for both Tsumo and Ron wins.

  2. 02

    Calculate fu points

    This capability determines the Fu (point base) for a winning hand. It processes the specific characteristics of the hand to find the correct base.

  3. 03

    Calculate hand value

    This capability calculates the total Han count and identifies all applicable Yaku for a Mahjong hand. It looks at the tile composition to find the value.

Real work

What teams actually run

01

Automated Game Scoring

An AI agent tracks a game and uses the MCP to settle scores after every hand.

02

Hand Analysis

You provide a list of tiles to your agent to quickly see the total Han and Yaku.

03

Rule Verification

Use the MCP to double check if a specific hand configuration results in the expected Fu or Han.

04

Bot Development

Integrate the scoring logic into a Mahjong bot via an MCP-compatible client.

One connector, every AI

Mahjong Scoring 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.

Building your own app? The connector is yours to use.

You don't need a client to put Mahjong Scoring 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.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Mahjong Scoring Engine, so you can see the experience inside your AI.

It does not authenticate your account with Mahjong Scoring Engine. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.
