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.

Who it's for

Built for the work Freelancer Budget Prover owners hand off.

Independent professionals who need to ensure their business model covers their actual cost of living and taxes.

  • 01

    Freelance Designers

    Hand off project estimates to the AI to check if the proposed rate covers non-billable design time.

  • 02

    Independent Consultants

    Use the capability to validate annual revenue projections against realistic client acquisition cycles.

  • 03

    Software Contractors

    Check if contract rates account for the high cost of capabilities, hardware, and self-employment taxes.

FAQ

Questions Freelancer Budget Prover owners ask.

  • 01

    How does this MCP differ from a standard spreadsheet?

    A spreadsheet just does the math you tell it to do. This MCP acts as a financial auditor that identifies logical flaws, like ignoring non-billable time or underestimating taxes.

  • 02

    What AI clients can I use with this?

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

  • 03

    Do I need to provide all my expenses every time?

    The capability works best when you provide a complete picture of revenue, costs, cash flow, pricing, and profitability to ensure a valid budget check.

  • 04

    Can this help me set my hourly rate?

    Yes. It calculates a minimum viable rate based on your specific costs and billable hours rather than just looking at what competitors charge.

  • 05

    How does it handle late payments?

    The capability factors in the statistical reality that many freelancers face late payments, helping you build a cash flow buffer.

  • 06

    Why is $100/hr × 2,080 a fantasy?

    Freelancers are billable 60-70% of working hours after admin, sales, learning, and vacation. Real: 1,352 hours × $100 = $135,200. not $208,000.

  • 07

    How do I calculate minimum viable rate?

    Total costs ($82K) ÷ (1 - target margin 20%) = $102,500 ÷ 1,300 billable hours = $78.85/hr minimum. Below this you lose money.

  • 08

    How does scope creep destroy profitability?

    20h project at $100/hr = $2,000. Client adds 'small changes.' Actual: 35h. Effective rate: $57.14/hr. 43% reduction. If minimum viable is $79/hr, you worked 15 hours below cost.
