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 Local Math Engine.

  1. 01

    Calculate amortization

    This capability generates a precise amortization schedule using either SAC or PRICE systems. It ensures every monthly principal and interest calculation is mathematically perfect.

  2. 02

    Calculate compound interest

    This capability calculates exact compound interest over a specified timeframe. It handles projections for initial investments and recurring monthly contributions.

Real work

What teams actually run

01

Loan Comparison

Compare the total interest paid between a SAC and a PRICE loan for the same principal.

02

Retirement Modeling

Project how monthly contributions will grow over 20 or 30 years using compound interest.

03

Mortgage Planning

Generate a full 360-month schedule to see exactly how much interest is paid each year.

04

Investment Projections

Calculate the final balance of an investment after years of monthly deposits.

Automate a task

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

Local Math 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 Local Math 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.

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 Local Math Engine, so you can see the experience inside your AI.

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

This MCP is built for professionals who need to hand off complex financial modeling to an AI agent without risking mathematical errors.

  • 01

    Financial Analysts

    They hand off the creation of detailed amortization tables and interest projections to the agent.

  • 02

    Mortgage Brokers

    They use the agent to quickly generate SAC or PRICE schedules for client loan scenarios.

  • 03

    Personal Finance Planners

    They delegate long-term compound interest modeling to the agent for retirement planning.

FAQ

Questions Local Math Engine owners ask.

  • 01

    How does this MCP prevent math errors?

    It offloads the math from the LLM to a deterministic TypeScript engine that follows strict mathematical rules.

  • 02

    What amortization systems are supported?

    The MCP supports both SAC (Constant Amortization) and PRICE (French Amortization) systems.

  • 03

    Do I need to provide my own API keys for math calculations?

    No. This MCP is self-contained and runs securely within Vinkius without needing external API keys.

  • 04

    Which AI clients can use this MCP?

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

  • 05

    Can I calculate compound interest with monthly contributions?

    Yes, the calculate_compound_interest capability handles both initial investments and monthly contributions.

  • 06

    Does this require an API key?

    No! It is a self-contained engine. It performs calculations directly within the Vinkius Edge process, meaning it does not rely on third-party APIs or external services.

  • 07

    Why use this instead of letting the AI calculate it?

    Because Large Language Models (LLMs) are text predictors, not calculators. If you ask an AI to generate a 360-month amortization table, it will hallucinate cents and make cascading mathematical errors. This MCP uses deterministic code to guarantee 100% banking-level accuracy.
