Your AI Agent Has Access to Your Stripe Keys. Here's How to Fix That.

#ai #fintech #security #opensource

If you're using AI agents for anything financial — invoicing, bookkeeping, crypto, payments — your agent probably has access to:

Stripe API keys
Bank account numbers
Crypto wallet files
Tax documents with SSNs
QuickBooks data

And there's nothing stopping it from leaking any of that in a prompt injection attack.

We just shipped ClawMoat Finance (v0.8.0) — a financial security module specifically for AI agents handling money.

What It Does

1. Financial Credential Protection

const { FinanceGuard } = require('clawmoat');
const guard = new FinanceGuard();

// Block agent from reading financial files
const check = guard.checkFilePath('~/.stripe/config');
// { allowed: false, findings: [{ label: 'Stripe credentials', severity: 'critical' }] }

30+ financial forbidden zones: Stripe, Plaid, MetaMask, Bitcoin wallets, QuickBooks, ACH files, tax documents.

2. Financial Secret Scanning

// Scan agent output for leaked secrets
const scan = guard.scanContent(agentResponse);
// Detects: Stripe keys, credit card numbers, SSNs,
// routing numbers, IBAN, crypto private keys, seed phrases
// Returns redacted version automatically

3. Transaction Guardrails

const guard = new FinanceGuard({
  transactionLimit: 1000,       // Approval above $1K
  dualApprovalThreshold: 10000, // Two people above $10K
});

const tx = guard.evaluateTransaction({
  amount: 5000,
  type: 'transfer',
  recipient: 'vendor@company.com'
});
// tx.approved = false
// tx.requiresApproval = true

// Human approves
guard.approveTransaction(tx.transactionId, 'cfo@company.com');

4. Financial API Monitoring

Tracks calls to 15 financial APIs (Stripe, Plaid, Coinbase, QuickBooks, Xero, etc.) and alerts on dangerous operations like POST to /charges or /transfers.

5. SOX & PCI-DSS Audit Reports

const report = guard.generateReport({ format: 'sox' });
// Complete audit trail: every transaction, every access attempt,
// every alert — formatted for compliance
