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.

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.
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.
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.

- 02

This MCP works with any compatible client, including Claude, Cursor, Windsurf, and VS Code.
- 04

- 05
How do I see all my options at once?
You can use the generate_comparison_report capability to aggregate all your different payment calculations into a single view.
- 06
How does the capability calculate the true APR for BNPL?
The calculate_bnpl_financials capability incorporates any provided late fees into the total cost of the installments, then annualizes that extra cost to show you the real interest rate you are paying.
- 07
Can I compare different credit card interest rates?
Yes, by using calculate_credit_card_impact, you can input various annual interest rates and durations to see exactly how much interest will accumulate on a specific purchase amount.
