# 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.

## Install

```shell
/plugin marketplace add bankbridge-money/bankbridge-plugin
/plugin install bankbridge
```

When prompted, paste your API token from [**bankbridge.money/dashboard**](https://bankbridge.money/dashboard). It’s pre-filled and copy-ready on your dashboard — just hit the big Copy button.

You’ll need:
- **A BankBridge account** — [sign up](https://bankbridge.money) ($5/mo per connected bank)
- **At least one bank connected** — linked on the dashboard in ~30 seconds

That’s it. The plugin handles the rest.

## 19 slash commands, included

Type `/` in any Claude Code session to find them. Each wraps a multi-step flow with an opinionated output shape, so you don’t have to hand-craft the prompt.

> **Also in Claude iOS / Android / Desktop / Cowork.** The same 19 commands are exposed as MCP prompts, so they appear under the **+** button in the chat input bar — one tap fills the full prompt. In Cursor, ChatGPT, and other MCP clients, they show up in whatever prompt-picker UI that client provides.

## Privacy & security

Your transactions never touch our servers. **We never store them.**

| | |
|---|---|
| **We don’t keep your data** | Every question your agent asks live-fetches in real time. No transaction cache, and no record of what you asked or what came back. |
| **Read-only access** | Your agent can read balances and transactions. Nothing can move money, pay a bill, or change your accounts. |
| **Bank-grade encryption** | AES-256-GCM for access tokens at rest. HTTPS everywhere. |
| **Revocable right away** | Disconnect a bank or delete your account anytime, and the connection is revoked and deleted right away. |
| **Trusted banking rails** | Same infrastructure Venmo and Robinhood rely on. |

BankBridge re-fetches on every question instead of caching your financial history. Details: [bankbridge.money/security](https://bankbridge.money/security).

## 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.
