BankBridge for Claude

Your bank accounts, transactions, and investments — in plain English, right inside Claude.

Ask Claude things like "how much did I spend on restaurants last month?" or "find any subscriptions I've forgotten about" or "draft a budget from my actual last 3 months" — and get real answers from your real data.

One account. Every bank you use. Works with Claude Code, Claude Desktop, Claude.ai, ChatGPT, Cursor, Copilot, Gemini, Codex, and everything else that speaks MCP.

Under the hood — 12 MCP tools

Claude Code picks these automatically based on your question. You never have to name them, but here’s what’s available:

ToolPurpose
list_accountsAll connected bank accounts with current balances
get_accountDetail lookup for one account by id
list_transactionsFilter by date range, amount, category, account, pending flag
search_transactionsSubstring match on merchant name + description

connect_bankDeep-link into a bank-connect flow when no banks are connected

All read-only. BankBridge literally can’t move money, change passwords, or make trades.


Privacy & security

Your transactions live at your bank. We never store them.

We don’t keep your dataEvery question your agent asks live-fetches in real time. No transaction cache. No query log.
Read-only accessWe can see your transactions. We can’t move money.
Bank-grade encryptionAES-256-GCM for access tokens at rest. TLS 1.3 for everything else.
Revocable in secondsCancel or delete your account anytime — your bank access is revoked and deleted from our servers within seconds.
Trusted banking railsSame infrastructure Venmo and Robinhood rely on.

No mainstream competitor can say "we never store your transactions" — most cache your financial history server-side for speed. BankBridge re-fetches on every question instead. Slightly slower, dramatically more private.

Pricing

$5/month per connected bank. First bank unlocks the service. Each additional bank adds $5/mo, prorated when you connect it. Cancel anytime, access ends at the end of your billing period.

No free tier, no freemium, no trial. Just $5 per bank — it’s fair, predictable, and means we’re never tempted to monetize your data. We’re a real subscription business.
