Kubera works with Gemini.

Add Kubera as a connected app and Gemini can read your whole balance sheet: every bank, brokerage, crypto wallet, private fund, property, trust and entity.

It can update it too, once you say yes: add to a holding, log a dividend from your inbox, revalue a fund from its statement.

Gemini Save your custom app dialog showing Kubera's 31 actions, with the name field and Connect highlighted

Who can add custom apps. Google opens custom connected apps to personal Google Accounts, 18 and over, in the US, in English, with Keep Activity turned on. Work and school accounts can’t add them yet. Once connected on the web, Kubera is there in the Gemini mobile app too.

Kept the default name? Then it answers to @Kubera Mcp instead of @Kubera. You can rename it any time in Connected apps.

What to ask

Type @Kubera at the start of a message and Gemini reads your balance sheet live before it answers. Two examples from the demo account, as Gemini answered them.

Example 1 · The long view

Three years, with the jumps and drops

One question, and Gemini read 36 months of net worth history, found the peak, and noticed that the portfolio’s official start date changes the story.

KuberaChart my net worth over the last 3 years and point out the biggest jumps and drops.

Over the last three years (November 2023 to October 2026) your Clark portfolio grew from $5.83M to $17.44M, a net increase of $11.61M (+199.1%). Your official start date in Kubera is September 30, 2024 ($22.22M); measured from there, net worth is down $4.78M (−21.5%). The full window catches the mid-2024 onboarding of your holding company and real estate entities.

Example 2 · Private investments

Committed, called, and what’s left

Kubera tracks committed capital, cash flows, cost basis and fund schedules per holding. Gemini pulled all four across fifteen positions and totalled them.

Gemini can update Kubera too

Reading is the default. Changing anything takes two yeses: Gemini shows the before-and-after and asks, then shows its own Allow card for the Kubera action. Nothing moves until you confirm both.

1 · Change a holding

Add to a position in one line

Say what changed. Gemini finds the holding, works out the new quantity, shows the value Kubera will calculate, and waits.

After you say yes, Gemini asks once more with an Allow / Deny card for the update. Click Allow. It is Gemini’s guard, not Kubera’s, and it appears on every change.

KuberaAdd 0.5 BTC to my Bitcoin asset in the crypto sheet.

Found Bitcoin in your Clark portfolio under Crypto › Bitcoin (Coinbase, BTC). Before I update it, confirm the change:

Quantity5 BTC→5.5 BTC

Estimated value~$409,554→~$450,509

Value is calculated by Kubera from the live BTC price, not typed in.

Yes

✓ Bitcoin updated to 5.5 BTC in the Crypto sheet

2 · Inbox to cash flow

Log dividends and capital calls from email

With Google Workspace connected in Gemini, it can search the month’s notices, list every amount with its source, and propose the cash flows. Dividends land as Cash Out; a capital call as Cash In.

KuberaCheck my Gmail for dividend and capital-call notices this month and log them.

Two dividend notices and one capital call found. Proposed cash flows:

Dividend · Cash Out$4,812.40 received

Dividend · Cash Out$1,206.15 received

Capital call · Cash In$150,000 to pay

Yes

✓ Three cash flows added in Kubera

More to try, reads and updates. Type @Kubera in Gemini first, then click one to copy and paste it after.

Privacy, in short

Gemini sees only what you have put in Kubera, and only while it is answering you. It never sees your bank logins, because Kubera never stores them.

If something’s off

Five things that come up, and the fix for each.

There is no + Custom button, or custom apps are greyed out

Custom apps need a personal Google Account (not work or school), 18 and over, in the US, with Keep Activity on. Check Settings, Activity, and sign in with a personal account.

@Kubera doesn’t appear in the list

You may have kept the default name. Type @Kubera Mcp instead, or rename it to Kubera in Settings, Personal Intelligence, Connected apps.

Gemini answers from memory, not from Kubera

Start a new chat and put @Kubera at the front of the message. The mention is what tells Gemini to fetch live data.

An Allow / Deny card appears on every change

That is Gemini’s own guard for custom-app actions. Click Allow when the tool shown is the one you asked for; Deny stops it.

Numbers look old

Gemini reads whatever Kubera holds right now. If a linked account hasn’t refreshed, refresh it in Kubera and ask again.

Questions

Do I need a paid Gemini plan?

Google doesn’t list a plan requirement for custom connected apps. What it does require is a personal Google Account, 18 or over, in the US, in English, with Keep Activity turned on. Work and school accounts can’t add custom apps yet.

Does it work on my phone?

Yes. Connect it once in Gemini on the web and it is available in the Gemini mobile app on the same Google Account.

Why does Gemini ask twice before it changes anything?

The first yes is to the before-and-after it shows you. The second is Gemini’s own Allow / Deny card for the Kubera action it is about to run. Both are there so nothing changes by accident.

Can Gemini change things in Kubera?

Yes, when you ask. It can add to a holding, log dividends and capital calls from your inbox, or update a fund from its statement. Every change is shown first and applied only after you confirm. It cannot move money. Everything it changes shows in Kubera’s history.

Does Kubera see my chats?

No. Gemini sends Kubera a request for data, Kubera answers, and that is all Kubera sees.

I use ChatGPT or Claude too. Same setup?

No, each AI connects differently. See the full list of supported AI assistants.
