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.

Real work

What teams actually run

One connector, every AI

Break-Even Calculator 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.

FAQ

Questions Break-Even Calculator owners ask.

  • 01

    What is the difference between accounting and economic break-even?

    Accounting break-even only looks at explicit fixed costs. Economic break-even includes those fixed costs plus implicit opportunity costs.

  • 02

    How do I use this with Claude?

    You connect the MCP through the Vinkius platform. Once connected, you can simply ask Claude to perform the calculations using the provided capabilities.

  • 03

    Can this capability calculate my margin of safety?

    Yes, the evaluate_margin_of_safety capability compares your current sales against your break-even point to find your cushion.

  • 04

    Do I need to provide my own formulas?

    No, the capabilities handle the math. You just provide the raw numbers like fixed costs and contribution margins.

  • 05

    Is this MCP ready to use immediately?

    Yes, Vinkius hosts the MCP, so you can connect and start using the capabilities right away.

  • 06

    How do I use the margin of safety capability?

    Use evaluate_margin_of_safety by providing your current sales volume, unit selling price, contribution margin, and fixed costs. It will return how many units your sales can drop before you hit the break-even point.

  • 07

    What is unit contribution margin?

    It is the amount of revenue remaining from a single unit sale after all variable costs associated with that unit have been subtracted.
