A sample conversation with an AI assistant connected to bank accounts through Fizen MCP.

Three steps to your first question

  1. Step 01

    Connect your bank on the Fizen website

    Choose your bank, log in there and select the accounts. You confirm consent in the bank, and Fizen never sees your password.

  2. Step 02

    Add Fizen to your assistant

    In the settings of Claude, ChatGPT or another MCP-enabled assistant, add the https://mcp.fizen.com server and sign in to Fizen.

  3. Step 03

    Ask in plain language

    About balances, spending, customer payments or a monthly summary. The assistant answers from your account data.

What the assistant can and cannot do

It can

  • Check balances on the accounts you selected
  • Search and summarise transactions
  • Total spending by category and compare months
  • Check whether a specific payment has arrived
  • Prepare a summary for your accountant

It cannot

  • Make a transfer or any other payment
  • See your password or banking credentials
  • Access accounts you did not select
  • Keep working after you revoke consent or it expires
  • Change any settings of your bank account
