How to connect your bank to Claude

4 min read
Sign up at bankbridge.money, link your bank through the dashboard, copy the pre-filled snippet for your flavor of Claude (Code, Desktop, or web), and paste it in. Claude can then ask for balances, transactions, recurring charges, and holdings on your behalf without ever caching your data locally.

1. Sign up + connect your bank

Head to bankbridge.money/login and sign in with your email. We send a magic link, no password. Once you’re in, the dashboard will prompt you to connect a bank.

The link flow happens inside a secure, bank-provided UI. You search for your institution (Chase, Bank of America, Capital One, your local credit union, etc.), enter the login you’d use on the bank’s website, and approve read-only access. BankBridge stores only an encrypted access token; we never see your bank password, and you can revoke access any time.

If you want investment data too (holdings, buys, sells, dividends), make sure to connect a brokerage like Fidelity, Schwab, or Robinhood. They show up in the same link flow.

2. Pick your flavor of Claude

BankBridge works with every MCP-speaking version of Claude. Each has its own one-screen setup on our docs:

  • Claude Code — one-line CLI install, or add the plugin from our marketplace.
  • Claude Desktop — Custom Connector. Paste the endpoint + bearer in the Connectors UI.
  • Claude.ai web — same Custom Connector flow, from your browser.
  • Claude Cowork — same pattern, works in the shared workspace context.

Each doc page auto-fills your real bbk_ key into the snippet when you’re signed in. You can literally copy-paste.

3. Test it with one question

Open a new Claude conversation and type:

“List my bank accounts and current balances.”

Claude should call list_accounts and report back with your checking, savings, credit card, and any brokerage accounts, plus balances. If this works, you’re wired up.

What to try next

Once the first query works, try these:

  • “How much did I spend this month?”
  • “What are my recurring subscriptions?”
  • “Show me every charge from Whole Foods.”
  • “How are my investments doing this quarter?”
  • “Break down my spending by category since Jan 1.”

For longer workflows, use our plugin slash commands like /monthly-money-review or /subscription-auditor — they run a pre-baked prompt against all 12 tools in sequence.

FAQ

Does Claude see my bank login?

No. The link flow happens in a secure bank-provided UI. BankBridge stores only an encrypted access token; Claude only ever sees the data our MCP tools return (balances, transactions, holdings).

Which Claude products work with this?

All of them that support MCP: Claude Code (CLI and plugin marketplace), Claude Desktop (Custom Connector), Claude.ai web (Custom Connector), and Claude Cowork. Each has its own one-screen setup on our docs.

What does it cost?

$5/mo per connected bank. One bank is $5/mo. Two banks is $10/mo. Cancel any time from the dashboard and billing stops immediately.

Can I revoke access later?

Yes. Disconnect the bank from the dashboard, or rotate your API key from the settings page. Old keys are invalidated instantly.
