How it works
01
Link your bank account
Securely connect to over 20,000 banks and financial institutions through Plaid, MX, or Mastercard. Your credentials never touch our servers.
Install the Skill or MCP server
Skills are lighter, just a markdown file and an API key. MCP servers run a local process. Pick whichever your AI supports.
# View, copy, and install the Skill from the Connect tab
# in the app. It has per-agent setup instructions.
export OPENFINANCE_API_KEY="of_..."
The Connect tab in the app shows the Skill, a copy button, and install steps for your agent.
03
Ask your AI about your money
Your AI can now read transactions, balances, and spending patterns. Just ask.
how much did I spend on food last month?
Features
Use your own AI
Works with Claude, ChatGPT, Cursor, or any AI that supports Skills or MCP. No lock-in, no middleman.
Completely open source
No tracking, no analytics, no hidden fees. Read every line of code yourself.
We don't use your data
Data syncs so the product works, but we never sell it, train on it, or use it for anything else.
Always up to date
Transactions sync automatically so your AI always has the latest picture of your finances.
