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.

Automate a task

Put Fundamental Math 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

Fundamental Math 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 Fundamental Math 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.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 5 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 Fundamental Math, so you can see the experience inside your AI.

It does not authenticate your account with Fundamental Math. 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 Fundamental Math owners hand off.

This MCP is for anyone using AI agents for tasks where a single decimal error makes the output useless.

  • 01

    Data Analysts

    They hand off statistical and arithmetic tasks to ensure precision.

  • 02

    Financial Professionals

    They use it to verify budget allocations and percentage calculations.

  • 03

    Developers

    They integrate it into workflows that require exact mathematical outputs.

FAQ

Questions Fundamental Math owners ask.

  • 01

    How does this prevent AI math hallucinations?

    Instead of the AI guessing the answer, it uses this MCP to run a real, deterministic calculation. The result comes from a math engine, not a probability model.

  • 02

    Is my data safe when using this MCP?

    Yes. The math is executed locally in JavaScript. No data is sent to external APIs for these calculations.

  • 03

    Which AI clients can use this?

    Any MCP-compatible client can use it, including Claude, Cursor, Windsurf, and VS Code.

  • 04

    Does this require a subscription to a math API?

    No. Vinkius hosts the MCP, and it uses local computation to provide results.

  • 05

    Can it handle complex math like factorials?

    Yes. It includes specific capabilities for factorials, square roots, powers, and the rule of three.

  • 06

    Why use this instead of asking the AI to calculate it?

    AI models predict the next token; they don't actually compute math. This leads to subtle and dangerous errors in calculations. This MCP forces the AI to use a deterministic JavaScript engine, ensuring absolute precision.

  • 07

    Does this server require an internet connection or an external API?

    Absolutely not. It is built entirely on pure, local JavaScript logic. It requires zero configuration, zero API keys, and guarantees that your sensitive data never leaves your infrastructure.

  • 08

    How does the 'Rule of Three' capability work?

    The Rule of Three capability solves proportional logic instantly. If you know that 100 units cost $50, you can pass A=100, B=50, and C=250 to find exactly how much 250 units will cost. The agent will handle the correlation automatically.
