Get Breadbox running with Docker in under five minutes.

Bank Connections

Connect Plaid, Teller, or import CSV files from your bank.

AI Integration (MCP)

Let Claude and other AI agents query your financial data securely.

How Breadbox works

1

Deploy

Run a single Docker Compose command to start Breadbox and PostgreSQL on your own machine or server.
2

Connect your banks

Use the admin dashboard to link your bank accounts via Plaid or Teller. Or upload CSV exports from your bank.
3

Sync automatically

Breadbox polls your banks on a schedule and via webhooks, keeping your transaction history up to date.
4

Query your data

Use the REST API, the admin dashboard, or connect an AI assistant like Claude to analyze and categorize your spending.

​

API key auth

Generate scoped API keys (full access or read-only) for integrations and AI agents.
