cashbff is a
personal finance mcp.
CashBFF is a remote MCP server that securely connects your bank to Claude, so you can ask about your real money right inside the chat you already use. Ask how much you have, what is coming up, or whether you can afford something, and Claude answers using your actual balances, transactions, and upcoming bills.
It runs on the Model Context Protocol, the open standard Anthropic introduced for connecting AI assistants to real data. CashBFF is hosted, OAuth-secured, and installs as a custom connector in Claude.

how it keeps your money safe.
CashBFF is built to be careful with your money and your data. Here is exactly how it works.
- Plaid only
- CashBFF reaches your bank through Plaid, the same provider behind apps like Venmo and Robinhood. Your bank login stays between you, your bank, and Plaid.
- Encrypted
- Your Plaid access tokens are stored with AES-256-GCM encryption at rest.
- Read-first
- By default, CashBFF reads your financial picture: balances, transactions, recurring expenses, scheduled forecasts, and the last four digits of an account.
- Money stays put
- CashBFF keeps your money exactly where it is, and full account and routing numbers stay private. It works from the last four digits of an account.
- You approve writes
- Write actions stay turned off until you enable them. Each one shows you a preview and asks for your confirmation first, and edits apply to entries you created yourself.
