AI payment and finance connectors

Connect QuickBooks Online, Square, Bill.com and other finance apps to Claude, Cursor and ChatGPT, with every tool call checked and logged.

Apps: The app catalog in ContextGate
Also: any remote MCP server
Price: Free

Connect your payment, billing and accounting apps to Claude, ChatGPT, Copilot and other AI apps through one MCP connection. Payment tools can move money, so ContextGate lets you switch each tool on or off and keep tools such as refunds and payouts switched off until you choose to use them. Every call is checked against your policies before it runs and recorded in Activity.

Finance apps hold the data AI apps are most often asked about, and the data you least want to leak: customer names, account numbers, invoices and payments.

You connect an app once. Look for it in the app catalog in ContextGate, or add any remote MCP server that reaches it. A third-party integration provider holds the OAuth grants for catalog apps. Each connection's tools are listed and synced, and you can switch off any tool you do not want used, such as one that issues refunds or deletes invoices. Switched-off tools are hidden from your AI apps and refused if called.

Every call through ContextGate is checked against your workspace's policies. PII redaction replaces personal data in tool results with placeholders before the AI app sees it; the built-in types include IBANs, account numbers and UK sort codes. Secret blocking stops any call whose arguments contain an API key or other secret. A governance check is a plain-English rule, judged by a model ContextGate manages, that blocks, warns on or logs a call. Every call shows up in Activity with the tool, its arguments, the redacted result and the policy outcome.

To reach one of the banks listed in this category, add a remote MCP server that connects to it, and its tool calls are checked and logged the same way.

How AI payment connectors stay safe

  • ✓Keep the tools that read balances, invoices and transactions on, and switch off tools that move money, such as refunds and payouts, until you need them.
  • ✓Policies block or warn on high-impact calls and redact card numbers and sort codes in results.
  • ✓Keys and sign-ins are held once, in the workspace vault or by the integration provider, not pasted into each AI app.
  • ✓One activity log for every call, whichever AI app made it.

Frequently Asked Questions

Which finance apps can I connect?

Any finance app in the app catalog in ContextGate, plus any remote MCP server. The catalog is listed in the app, so check there for a specific one.

Can ContextGate connect to my bank?

Not with a built-in integration. The bank pages in this directory are for reference. If you have a remote MCP server that reaches your bank, add it, and every tool call through it is checked against your policies and logged.

How do I keep account numbers away from the AI app?

Use PII redaction. Personal data in tool results is replaced with placeholders before the AI app sees it. Built-in types include IBANs, account numbers and UK sort codes, and you can add custom patterns. If the AI app sends a placeholder back in a later call, the tool gets the real value.

Can I stop an AI app from moving money?

Yes, in two ways. Switch off the tools that create payments or refunds: they are hidden from your AI apps and refused if called. Or keep them on and add a governance check that blocks or warns on those calls based on their arguments.

What does ContextGate record?

Activity records each tool call that goes through ContextGate, with the arguments as sent and the result after redaction. Secrets that get blocked are kept out of the log. ContextGate sees only those tool calls, not your AI app's chat or built-in tools. It runs on Google Cloud in the US (us-central1).
