How does the MCP handle multiple discounts?

It uses the percentage_stacking capability to apply discounts sequentially, ensuring the math follows the correct order.

Can this capability calculate sales tax?

Yes, the regional_taxation capability calculates final prices based on specific regional tax rules.

Does it support BOGO offers?

Yes, the bogo_logic capability is specifically designed to calculate the impact of Buy One Get One promotions.

What clients can I use this with?

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

How are fixed amount coupons handled?

The fixed_reduction capability is used to subtract specific currency amounts from the total.

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.
