Setup guide
Connect Codex to your bank accounts
Codex reads MCP servers from its own config file. Add BankingMCP there, or run the add command, and ask in your next session.
Before you start
- 01Create a BankingMCP account. The first 7 days are free and need no payment details.
- 02Connect your bank through its own PSD2 web form. Your banking login stays with your bank.
- 03Add Codex as an assistant to get a personal MCP address for it.

OpenAI Codex CLI & IDE
Setup steps
- 01Copy your personal MCP address from BankingMCP.
- 02Add the entry shown here to
~/.codex/config.toml, or runcodex mcp add bankingmcp --urlfollowed by your address. - 03Start a new Codex session and ask about your accounts.
~/.codex/config.toml
[mcp_servers.bankingmcp] url = "https://banking-mcp.com/api/mcp/<your-token>"
This address is an example. You get your own after signing up, and it works like a password.
What Codex can do once it's connected
- list_accounts
- Lists your connected accounts with bank, IBAN and balance.
- get_balances
- Totals across all accounts, per currency, plus each account's balance.
- search_transactions
- Finds transactions by account, date range, merchant or purpose, income or spending and amount, with totals.
- list_transactions
- Loads all transactions page by page, optionally per account and date range, so your assistant can sort through them itself, e.g. for rent payments.
- refresh_accounts
- Fetches current data from your banks before answering.
These tools only read. Nothing can move money, and payments are not part of this connection.

Questions about Codex and BankingMCP
- Does Codex see my banking login?
- No. You log in at your bank in its own web form. BankingMCP never receives your PIN or password, and neither does Codex.
- Can Codex move money?
- No. This connection is read-only: listing accounts, balances and transactions. There is no payment tool. Payments are planned as a separate, explicitly approved step.
- What happens if I want to cut off access?
- Each assistant has its own address. Deactivate or remove the one you gave Codex and it stops working immediately, without touching your other assistants.
