Best MCP servers for UK personal finance (2026)
Best personal finance MCP servers for the UK in 2026: Era, PocketSmith, Aureli, Wallet and YNAB community servers compared on UK banks and open banking access.
The best personal finance MCP server for the UK in 2026 is Era, because it connects your UK current accounts, savings and cards through open banking and lets Claude, ChatGPT and Gemini read them with one shared memory. PocketSmith, Aureli, Wallet and the YNAB community also offer servers, and this guide shows which suits which kind of UK money.
What is a personal finance MCP server?
A personal finance MCP server is a connector that lets an AI assistant read your financial data through the Model Context Protocol, the open standard that Claude, ChatGPT, Cursor and many other assistants use to reach outside tools. You add the server to your assistant, approve access once, and the assistant answers from your real accounts.
Some servers are read-only and some let the assistant write too, and the best let you decide. What is MCP explains the idea in plain words.
What is the best MCP server for UK banks?
The best MCP server for UK banks is one that reaches many of them through open banking and keeps access under your control. Era connects UK current accounts, savings and cards across providers, where a bank's own tools reach only its own customers, and it is the one built to serve several assistants at once.
Era
Era runs a personal MCP server that connects your accounts to any assistant that supports the protocol. You sign in with OAuth, or with an API key, and the assistant reads your balances and transactions, your holdings, your financial health and the analysis behind it.
Around the data, memory is shared between assistants, the Document Library reads payslips, P60s and statements with citations, and shared spaces let a household work from one view. Era also has a REST API that does what MCP does, for people who build their own tools. Era is best for anyone who wants one connection across every UK bank and every assistant. How developers use Era Context MCP shows it in use.
PocketSmith
PocketSmith published an official MCP server in April 2026, and Claude's directory has listed it since 25 August. It brings the app's forecasts and budgets to your assistant, with bank feeds from around the world. Its prices are in US dollars, from US$9.99 a month.
PocketSmith is best for people who already use it to forecast their balance.
Aureli
Aureli is a UK net-worth tracker whose free tier includes an MCP connection for Claude, ChatGPT, Gemini and Grok. It connects named UK banks, and it is a registered agent of an FCA-authorised provider.
Aureli is best for people who mainly want an assistant to read their net worth.
Wallet by BudgetBakers
Wallet's MCP server works with Claude, ChatGPT, Cursor and Windsurf. It is read-only by default and lets you opt in to writing, and BudgetBakers cites more than 15,000 bank connections across Europe.
Wallet is best for people who already budget in Wallet.
YNAB community servers
YNAB has a public API and direct import from select UK banks, but it has no official MCP server. Developers in its community have built several that let an assistant read and update a YNAB budget, and their quality varies from project to project.
They are best for committed YNAB users who are comfortable setting up a community project.
What about banks that offer their own tools?
Some UK banks offer assistants or developer tools of their own. Starling launched an Assistant in March 2026 for its own customers, Revolut began offering its AI assistant to UK customers in April 2026, and Monzo publishes a developer API that its documentation says is not suitable for building public applications.
Each of these sees only its own accounts. They suit quick questions about one bank, and an MCP server that spans your banks suits the questions that cross them.
The servers compared for UK users
The table shows where each one reaches.
| Server | What it covers | UK banks | Access | Best for |
|---|---|---|---|---|
| Era | Accounts, cards, investments, documents, memory, financial health | Across the UK through open banking | Read and write, you choose | One connection for every assistant |
| PocketSmith | Budgets and forecasts | Bank feeds worldwide | Official server | PocketSmith users |
| Aureli | Net worth | Named UK banks | Free MCP tier | Net-worth tracking |
| Wallet | Budgets and transactions | European banks | Read-only by default | Wallet users |
| YNAB community | A YNAB budget | Select UK banks | Varies by project | YNAB users |
Which MCP server works with Claude and ChatGPT in the UK?
All of the servers above work with Claude and most work with ChatGPT, because both support the protocol. Claude's own finance feature is built for US banks, so in the UK a server is how your assistant reaches your banks, and Era is built to serve several assistants at once so that they read the same accounts.
Claude Personal Finance, launched on 5 November 2026, links US banks only, as Anthropic's help centre says. To connect Era to Claude, follow how to connect Claude to your bank account.
Is it safe to connect an MCP server to your UK bank?
It is safe when the access is scoped, revocable and logged. Era uses open banking, which is regulated and needs no bank password, plus OAuth 2.1 for assistants, and it records every call an assistant makes. Money movement is in private beta, off by default for every key, and every transfer needs your approval.
When you compare servers, ask whether access is read-only by default, whether you can revoke it, and whether you can see what the assistant did. Is it safe to give AI your financial data goes through each one.
What can you ask once an MCP server is connected?
Once an MCP server is connected, your assistant can read your accounts and answer in plain words, so you can ask for a summary, a comparison or a check instead of opening several screens. It can total a category, compare two months, list what is due this week, and cite the statement behind a figure.
- How much did I spend on eating out across all my banks last month?
- Which direct debits are due before payday?
- Compare my January and February spending and tell me what moved most.
- Find the P60 in my documents and tell me my total pay for the tax year.
Because Era keeps the memory, the assistant already knows your goals and your household when you ask, and the same questions work in whichever assistant you connect.
Where should you start?
Start with the money you ask about most. If it is everything, connect Era and add your assistants one at a time, and if it is a single product, the official server for that product is the quickest route, with Era available later without losing anything.
For the apps behind these servers, best budgeting apps in the UK (2026) compares eight of them, and best AI budgeting apps in the UK (2026) looks at how each handles AI.
Era connects accounts across the US, the UK, Canada, France, Germany, Spain, and 40+ countries in all.
