Connect Tomorrow to Codex

This guide gives Codex read-only access to your Tomorrow account. You sign in to Tomorrow once in its own web form, add BankingMCP to Codex, and ask about balances and transactions. No app, no code.

BankingMCP€5 a month

Short answer

Yes, Tomorrow works. It is in the bank directory BankingMCP connects through, via XS2A (PSD2). Your assistant gets your balance and transactions, read-only, for €5 a month after a 7-day free trial. Nothing to install. Codex reads your Tomorrow accounts through BankingMCP: list accounts, read balances, search transactions. It cannot move money.

Guide: connecting Tomorrow to Codex

Two parts, about five minutes: first you share your Tomorrow accounts with BankingMCP, then you add BankingMCP to Codex.

Share Tomorrow with BankingMCP

  1. Create a BankingMCP account and start the 7-day free trial. You add payment details at Stripe, and you pay nothing if you cancel within the trial.
  2. In BankingMCP, search for “Tomorrow” and sign in to Tomorrow in its own web form. Your banking credentials never reach us.

Add BankingMCP to Codex

  1. In BankingMCP, add Codex as an assistant and copy its personal MCP address.
  2. Add the entry shown here to ~/.codex/config.toml, or run codex mcp add bankingmcp --url followed by your address.
  3. Start a new Codex session and ask about your accounts.
  4. Ask Codex your first question, for example: “What's the balance on my Tomorrow account right now?”
~/.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.

Good to know about Tomorrow

  • Banks ask you to confirm access again after a set period. BankingMCP shows you when the Tomorrow consent expires; after that you log in once more.

Check Tomorrow

Answered live from the bank directory. If your exact institution shows up here, BankingMCP can connect to it.

Searching…

Tomorrow runs on Solaris

Tomorrow's accounts are held at Solaris SE, its banking partner, so the bank directory lists it as “Tomorrow (Solaris)”. Search for “Tomorrow” when you connect, not for Solaris: Kontist and other brands share the same bank code.

Tomorrow is a personal account with a sustainability focus. Your assistant sees its balance and transactions – handy for checking what your spending actually goes to.

Seven subscriptions charged your Tomorrow account in the last 12 months, together €1,086.40 a year. Two of them do the same job: you pay for two cloud storage plans.

Example conversation with fictional names and amounts.

What you can ask Codex about Tomorrow

  • “How much did I spend on flights and fuel this year?”
  • “What's the balance on my Tomorrow account?”
  • “Which subscriptions are still charging my Tomorrow account?”
  • “How did my spending on groceries change over the last six months?”

Connecting Tomorrow through regulated bank access

  • Read-only. Over MCP your assistant only gets read tools: it can list accounts, read balances and search transactions. There is no payment tool in this connection.
  • You log in at Tomorrow itself. Access runs through finAPI, a PSD2-licensed account information service, and your banking credentials never reach BankingMCP.
  • BankingMCP doesn't keep your balances and transactions; it fetches them for each question your assistant asks. Only account details and an access log, kept for 90 days, are stored.
  • Every assistant gets its own address. Deactivate one and its access to your Tomorrow account stops immediately.

Questions about Tomorrow

What is MCP?
The Model Context Protocol is an open standard that lets AI assistants like Claude or ChatGPT use outside tools. BankingMCP makes your Tomorrow account available as an MCP server, so your assistant looks up balances and transactions directly instead of you uploading bank statements.
Does BankingMCP support Tomorrow?
Yes. Tomorrow is listed in the bank directory with a XS2A (PSD2) interface, which is how BankingMCP connects. The live check on this page confirms your exact institution.
Do I need to install an app to use Tomorrow with Codex?
No. BankingMCP runs in the browser on any computer or phone. You connect Tomorrow once, then add one address to Codex.
Does my assistant see my Tomorrow balance?
Yes, along with your transactions. Your assistant reads the balance when it asks, together with the time Tomorrow last delivered it.
How up to date are my Tomorrow transactions?
Your assistant fetches your balance and transactions with every question and gets them as Tomorrow last delivered them, with a timestamp. If the Tomorrow consent expires, it only sees the last state until you log in again – and tells you so.
Can I use Tomorrow together with other banks?
Yes. Connect up to 50 accounts across several banks, personal and business. Your assistant answers across all of them, and the price stays at €5 a month.
Does my assistant see my Tomorrow login?
No. You log in at Tomorrow in its own web form. Neither BankingMCP nor your assistant ever receives your PIN, password or TAN.
Do I need programming skills to use Tomorrow with Codex?
No. You connect Tomorrow in the browser and add one address to Codex. Every assistant has a step-by-step guide.
Can my assistant transfer money from my Tomorrow account?
No. The connection is read-only and has no payment tool. Payments are planned as a separate feature, where you approve every transfer in your own banking app.
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.
