How does this MCP handle taxes?

The MCP includes capabilities to apply specific tax rates or pull from predefined scenarios like VAT or US Sales Tax to ensure the final price covers the tax burden.

Can I compare different pricing strategies?

Yes, you can use the compare_regimes capability to pass multiple tax and expense configurations to see how they change your suggested selling price.

What is a markup divisor?

The markup divisor is the number used to convert your total cost and margin requirements into a final selling price. The MCP calculates this for you.

Which AI clients can I use this with?

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

Do I need to provide my own tax rates?

You can provide your own custom rates, or you can use the list_tax_scenarios capability to access common industry standards.

How does the markup calculation work?

The calculate_markup capability calculates a divisor by subtracting your tax rate, expense rate, and target profit margin from 100%. It then divides your product cost by this divisor to suggest a selling price that covers all obligations.

Can I compare different tax scenarios?

Yes, the compare_regimes capability allows you to provide multiple tax and expense configurations in a single request to see how each one affects your suggested selling price.

What happens if my total rates exceed 100%?

If the sum of your tax rate, expense rate, and profit margin is 100% or greater, the capability will return an error because a valid selling price cannot be mathematically determined.

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.

One connector, every AI

Markup 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.

Building your own app? The connector is yours to use.

You don't need a client to put Markup Calculator 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.
