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 · 2 capabilities

We ship only the actions that matter.

Capability set01 / 01

01-02

2 capabilities in this set.

Part of 2 available through Math.js.

  1. 01

    Round value

    This capability rounds a float value to a specific number of decimal places. You provide the expression as a string and the engine handles the precision.

  2. 02

    Calculate expression

    This capability evaluates complex mathematical expressions deterministically. It uses mathjs to solve strings like 1.2 * (2 + 4.5) without errors.

Real work

What teams actually run

01

Financial Modeling

An agent calculates interest rates or currency conversions with exact decimal precision.

02

Scientific Computing

Your agent processes complex formulas involving square roots and exponents.

03

Data Cleaning

The AI rounds large datasets of floating-point numbers to a standard format.

04

Automated Engineering Tasks

An agent evaluates structural or electrical equations provided by a user.

Automate a task

Put Math.js 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

Math.js 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 Math.js 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. 2 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 Math.js, so you can see the experience inside your AI.

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

This is for anyone building or using AI agents that need to perform reliable numerical work.

  • 01

    Data Analysts

    They hand off raw data strings to the agent to get clean, rounded results.

  • 02

    Software Developers

    They use this to ensure their AI-driven applications don't output broken math.

  • 03

    Financial Researchers

    They rely on the precision rounding to maintain decimal accuracy in reports.

FAQ

Questions Math.js owners ask.

  • 01

    How does this prevent AI math errors?

    It moves the calculation away from the LLM's probabilistic reasoning and into a deterministic mathjs engine.

  • 02

    Which AI clients can use this MCP?

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

  • 03

    Can I use this for rounding numbers?

    Yes, the round_value capability allows you to specify exactly how many decimal places you need.

  • 04

    Is there any latency when calculating?

    No, the execution happens within a V8 isolate, making it extremely fast.

  • 05

    Does this require an API key?

    No, Vinkius hosts the MCP, so you just connect and start using the capabilities.

  • 06

    Why use this instead of the LLM?

    Because LLMs are probabilistic text generators, not calculators.

  • 07

    Does it handle floating point bugs?

    Yes, mathjs evaluates expressions safely without the JS 0.300004 bug.

  • 08

    Can it round dynamically?

    Yes, you specify the exact decimal precision required.
