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

    Yes, you can use the compare_payment_strategies capability to see the difference in interest and time saved.

  • 03

    What AI clients can I use with this MCP?

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

  • 04

    Can I set a specific date to be debt-free?

    Yes, the determine_required_monthly_payment capability calculates the payment needed to hit a target date.

  • 05

    Does this provide a monthly breakdown?

    Yes, the math includes a month-by-month amortization table showing your progress.

  • 06

    How does the engine calculate interest?

    The engine uses daily compounding logic, dividing your APR by 365 to determine the daily rate. This ensures a highly accurate simulation of how credit card interest actually accrues.

  • 07

    Can I see a month-by-month breakdown of my payments?

    Yes. When using calculate_repayment_projection, the capability returns a detailed amortization table showing interest charged, principal reduced, and the remaining balance for every month.

  • 08
