Connect earmarkIQ to Claude.

Claude is the assistant we have tested the whole way through, from authorisation to answer. Once connected, it can answer questions about your actual spending, subscriptions, income and net worth — and it cannot change any of them.

What you need

An earmarkIQ account on Pro, with at least one bank connected, and an assistant that supports custom MCP connectors. Context is a Pro feature; it is not on the free tier or on Plus.

How to connect it

Open Claude's connector settings

Custom MCP connectors live in Claude's settings on its paid plans. Look for Connectors, sometimes shown as Custom connectors. The exact location moves between releases and differs across web, desktop and mobile — Anthropic's own documentation is the authority if what you see does not match.

Add earmarkIQ Context as a custom connector

Paste the address below. It is the same address for every user — it is not a secret and not a token.

Authorise, and choose your scopes

Claude will send you to earmarkIQ to sign in. You will see the five scopes listed and can grant them individually. Approve only what you want Claude to read.

Ask it something

If it is working, Claude will answer from your real figures rather than asking you for them.

The connector address

This is the same for everyone. It is not a secret and it is not a token — authorisation happens in the next step, and the connection is bound to your account then.

If your assistant asks for a token instead

Some clients cannot do the browser sign-in and ask for a bearer token instead. You can create one in earmarkIQ under Connected assistants. Manually created tokens expire after 90 days, and are shown once — if you lose one, revoke it and create another.

What to grant

Five scopes, each granted and revoked on its own. You do not have to grant all of them, and you can change your mind later without reconnecting.

ScopeWhat it lets the assistant read
SpendingCategory totals and how they move over time — groceries, transport, eating out.
TransactionsIndividual transactions: merchant, amount, date, category.
Balances & assetsAccount balances, property values and the net worth figure built from them.
IncomePay, when it lands, and how regular it is.
SubscriptionsRecurring payments, what they cost, and price rises.

Transaction history goes back 12 months by default and is capped at 24 months. There is no setting that lifts the cap.

What Claude can then answer

What did I spend on groceries last month, and is that normal for me?
Which subscriptions have gone up in price since January?
How much is genuinely spare after my bills and savings?

What it cannot do

Context is read-only by construction rather than by policy. There is no tool in it that writes, moves or changes anything, because no such tool has been built — and a test fails the build if one is ever added. That is a stronger guarantee than a setting you could switch off by accident.

What read-only does not cover

Read-only describes what Context can do to your data. It says nothing about what happens to the conversation once your data is inside the assistant. Whatever you ask Claude, ChatGPT or any other assistant is handled under that provider's privacy terms, not ours — and may be retained or reviewed according to their policy, not this one.

Grant the narrowest scopes that answer your question, and read the assistant provider's own terms before connecting anything. We would rather say that plainly than let read-only sound like a privacy guarantee it is not.

The access log

Every request an assistant makes is recorded and readable by you in the app: which tool ran, which scope it used, and when. It is not a summary or a sample — it is the list.

That matters more than any promise on a marketing page. A read-only claim you cannot audit is a claim you are taking on trust; a log you can open yourself is a claim you can check. If you connect an assistant and later wonder what it looked at, the answer is already written down.

How to revoke it

Two routes, both immediate:

Revoking access to Context does not touch your bank connection or your earmarkIQ account. It only closes the door the assistant was reading through.

Questions

How do I connect Claude to my bank account?
You do not connect Claude to your bank. You connect your bank to earmarkIQ under Open Banking, then add earmarkIQ Context to Claude as a custom connector using the address https://api.earmarkiq.app/mcp. Claude reads the picture earmarkIQ has already built. It never talks to your bank and never sees your banking credentials.
Does this work with the free version of Claude?
Custom MCP connectors are a paid-plan feature in Claude, and Context is a Pro feature in earmarkIQ, so you need a paid plan on both sides. Anthropic's own documentation is the authority on which Claude plans include custom connectors.
Is earmarkIQ an official Claude integration?
No. earmarkIQ Context is built on the Model Context Protocol, which is an open standard, and it works with Claude the way any custom connector does. It is not listed, reviewed, approved or endorsed by Anthropic, and we would not claim otherwise.
Can Claude spend my money or change anything?
No. Context contains no tool that writes, moves or changes anything, and a test fails the build if one is added. earmarkIQ connects to your bank under account information services only, and payment initiation is not enabled. Claude can read what you have granted and nothing else.
What does Claude do with my financial data once it has it?
That is governed by Anthropic's terms, not ours. Read-only describes what Context will do with your data, not what happens to the conversation afterwards. Grant the narrowest scopes that answer your question and read Anthropic's privacy terms before you connect.
How do I disconnect Claude from earmarkIQ?
Either revoke the connection in earmarkIQ under Connected assistants, which stops it on the next request, or remove the connector in Claude, which stops earmarkIQ being called at all. Neither affects your bank connection or your earmarkIQ account.
