Crush

# One line in crushrc.

A `crushrc` is a Bash script with Crush commands in it. One `mcp add` line connects BankBridge.

Read-only. Your agent can see balances and transactions, and nothing can move money, pay a bill, or place a trade. BankBridge doesn’t store your transactions. [How it’s secured](https://bankbridge.money/security) · [Try it with sample data first](https://bankbridge.money/demo)

Step 01

## Add this line to crushrc.

~/.config/crush/crushrc

```
mcp add bankbridge --type http --url https://bankbridge.money/api/mcp --header Authorization "Bearer bbk_your_api_key_here"
```

Restart Crush after editing the config.

Because the file is Bash, you can keep the key out of it: export `BANKBRIDGE_API_KEY` and write `"Bearer $BANKBRIDGE_API_KEY"`. Use `./.crushrc` instead for one project.

Step 02

## Verify it works.

Crush names the tools `mcp_bankbridge_*`. Open a new session and ask:

try this

```
list my bank accounts and balances
```

Or from a script: `crush run "list my bank accounts and balances"`.

To test the config before you sign up, use the key `bbk_demo`. It returns sample data.

Troubleshooting

Client connects but shows 0 tools.

Usually the client is caching an old config, or you're on a mode that doesn't expose tools (Ask/Edit vs Agent, for example).

**Fix:** Fully quit + relaunch the host app. In VS Code Copilot, switch to Agent mode.

401 Unauthorized on every call.

The API key is missing, typo'd, or got revoked. Check the Authorization header starts with \`Bearer \` (note the space) and ends in a key you still own.

**Fix:** Paste a fresh key from [Settings](https://bankbridge.money/dashboard/settings).

Tools return a NO\_CONNECTIONS warning.

You haven't linked a bank yet.

**Fix:** Visit [Connect a bank](https://bankbridge.money/dashboard/connect) . The bank-connect flow opens automatically, ~30 seconds.
