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.

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.

    Calculate kfold

    This capability generates exact K-Fold cross-validation indices for your train and test splits.

Real work

What teams actually run

01

Standard Model Validation

Generate 5-fold or 10-fold splits to test model accuracy on unseen data.

02

Time-Series Analysis

Create non-shuffled splits to maintain chronological order in temporal datasets.

03

A/B Testing Setup

Partition data into independent sets for controlled experiment testing.

04

Automated Pipeline Testing

Provide your agent with the indices needed to automate repetitive validation tasks.

Automate a task

Put Native V8 to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Native V8 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 Native V8 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. 1 capability arrives 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 Native V8, so you can see the experience inside your AI.

It does not authenticate your account with Native V8. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work Native V8 owners hand off.

This MCP is built for professionals working with predictive modeling and statistical validation.

  • 01

    Machine Learning Engineer

    Hands off the complex index math to the MCP to ensure model integrity.

  • 02

    Data Scientist

    Uses the capability to generate robust validation sets for statistical analysis.

  • 03

    Data Engineer

    Integrates the split logic into automated data pipelines.

FAQ

Questions Native V8 owners ask.

  • 01

    How does this MCP prevent data leakage?

    It moves the partitioning logic from the LLM to a dedicated engine that calculates exact indices, preventing the AI from accidentally overlapping training and testing data.

  • 02

    Can I use this for time-series data?

    Yes. You can instruct your agent to disable shuffling to preserve the strict chronological order of your data.

  • 03

    Which AI clients can use this MCP?

    You can use this with any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.

  • 04

    Do I need to host this myself?

    No. Vinkius hosts and manages the MCP for you, so it is ready to use as soon as you connect.

  • 05

    Can I specify the number of folds?

    Yes, you can request any K-fold configuration, such as 2-fold for A/B testing or 10-fold for standard validation.

  • 06

    Why does it return indices instead of data?

    Passing massive data payloads back and forth wastes LLM tokens. Returning lightweight index arrays is incredibly fast and resource-efficient.

  • 07

    Does it guarantee randomized fairness?

    Yes, advanced internal shuffling mechanisms guarantee that your K partitions are entirely unbiased before the split occurs.

  • 08

    Can it handle chronological time-series?

    Absolutely. Simply disable the shuffling parameter, and the engine will slice the data linearly, perfectly respecting time-based ordering.
