Open standard

Connect earmarkIQ to any MCP assistant.

earmarkIQ Context is a standard MCP server. Any client that speaks the Model Context Protocol can connect to it using the address below. We have verified Claude end to end; the rest use the same standard, and this page gives you what you need rather than a menu path we have not checked.

Why there is no click-path on this page

Assistant settings move between releases, and a wrong instruction wastes more of your time than no instruction. So this page gives you the address, the authorisation flow and the scopes — the things that do not change — and leaves the menu to your assistant's own documentation.

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.

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.

Authorising it

Add the address as a custom MCP connector

Wherever your client keeps custom connectors, MCP servers or tools.

Complete the browser sign-in

earmarkIQ supports the full OAuth flow with PKCE and dynamic client registration, so most clients need nothing configured by hand. You will be sent to earmarkIQ, asked to sign in, and shown the scopes being requested.

Or create a token, if your client needs one

Some clients cannot do a browser sign-in and ask for a bearer token. Create one in earmarkIQ under Connected assistants. Manually created tokens expire after 90 days and are shown once.

The scopes

Five, each granted and revoked separately.

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 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

Can I connect earmarkIQ to ChatGPT?
If your ChatGPT plan supports custom MCP connectors, then yes, using the same address as any other client: https://api.earmarkiq.app/mcp. We have not verified ChatGPT end to end, and assistant settings move often enough that publishing a click-path we had not checked would be worse than publishing none. Check OpenAI's own documentation for whether and where your plan exposes custom connectors.
Which assistants have you actually verified?
Claude, end to end, from authorisation through to a tool call returning data. Everything else uses the same open standard and is expected to work, but we have not tested each client and we will not imply that we have.
What is MCP?
The Model Context Protocol: an open standard for connecting assistants to external tools and data. It is not specific to earmarkIQ or to any one assistant. It is the reason a connector written once works with any client that speaks it.
Does my assistant need OAuth support?
It is the better route, and earmarkIQ supports the full flow including dynamic client registration, so most clients can connect without anything being configured by hand. If your client cannot do a browser sign-in, create a bearer token in earmarkIQ instead. Manually created tokens expire after 90 days.
Can any of these assistants move my money?
Not through earmarkIQ. Context contains no tool that writes, moves or changes anything, whichever client connects to it. earmarkIQ connects to your bank under account information services only and payment initiation is not enabled.
What if the assistant provider stores my financial data?
Assume it might, and read their terms. Once your figures are in a conversation, that conversation is governed by the assistant provider's privacy policy rather than ours. Granting fewer scopes is the most reliable protection.
