What is the difference between single-use and refillable unit costs?

Single-use costs focus on the immediate price per unit, while refillable costs account for the container price spread across multiple uses.

Can I include transport costs in the comparison?

Yes, you can provide a transport factor to ensure the economic model includes logistics impacts.

How do I find out when a refillable system becomes profitable?

Use the get_break_even_trips capability to find the exact number of trips required to beat single-use pricing.

Which AI clients can use this MCP?

You can use this with any MCP-compatible client like Claude, Cursor, or Windsurf.

Does this MCP require me to host anything?

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

How does the capability account for container deposits?

The calculate_refill_unit_cost capability accepts an optional containerDeposit parameter, which is included in the total cost calculation for the refillable system.

What is a transport factor?

The transport factor is a multiplier used to adjust costs based on the logistics and movement of goods, which can differ significantly between single-use and refillable models.

Can I find out when refilling becomes cheaper than buying single-use?

Yes, you can use the get_break_even_trips capability to calculate the minimum number of refill cycles required for the refillable system to be more economical than the single-use option.

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

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.

Compare refill feasibility
This capability compares a single-use product directly against a refillable system to find the cost-per-unit difference.
02
Get break even trips
This capability calculates how many refill trips are required for a refillable system to become cheaper than the single-use option.
03
Calculate single use unit cost
This capability determines the cost of a single-use product per unit of quantity.
04
Calculate refill unit cost
This capability determines the cost of a refillable product per unit of quantity across multiple uses.

Real work

One connector, every AI

Refill Cost Comparator 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 Refill Cost Comparator 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.
