Who it’s for


Founders	Several companies side by side, and what each one owes you
Businesses	Banks, cards, payments, invoices, bills and payroll in one ledger
Investors	Your holdings, and the stakes you hold in companies
Individuals	Just your own accounts, cards and cash, in a private space

Related MCP server: bank-mcp

What you can ask

Once it’s connected, just ask:

“How much cash do we have across all our companies, and how many months of runway?”
“Which invoices are overdue, and who owes us the most?”
“How are my investments doing?”
“How much is in my personal accounts right now?”
“I paid a contractor $500 in cash for Harbor Coffee. Add it.”
“What does each company owe me personally?”

Get started

	Hosted (about 2 minutes)	Self-host (about 10 minutes)
Where it runs	app.aggregate.finance	Your machine or server, with Docker or Node
Connections	Set up for you	Bring your own provider keys, or upload statements
Backups and updates	Done for you	Yours
Cost	Free during early access	Free (AGPL-3.0)
Start	Sign up, then connect your AI below	Run it yourself

Connect your AI

One line for each AI:

AI	How
Claude Code	`claude mcp add --transport http agfn https://app.aggregate.finance/mcp`
Cursor, VS Code, Windsurf, Claude Code	`npx aggregate-finance setup` (shows what it would change; add `--yes` to write it)
Cursor	One click:
Claude	Settings → Connectors → Add custom connector → paste the link below
ChatGPT	Add it as a connector and paste the link below

Or copy the link into any AI that supports MCP:

https://app.aggregate.finance/mcp

You sign in, then choose exactly what that AI can see in one plain sentence. Running your own server? Use https://<your-server>/mcp instead.

Agent skill. Teach your agent when to use these tools, the fixed definitions behind cash, burn and runway, and to stay read-only unless you ask (skills/aggregate/SKILL.md):

npx skills add Izzy-Gottz/aggregate-finance

Create a key in Connect your AI → Connect another AI → A bot or script. Keys look like agfn_live_…, are shown once and always expire. Send it as a header:

curl -H "Authorization: Bearer $AGFN_KEY" https://app.aggregate.finance/v1/overview

Or bridge it to a local MCP client over stdio:

AGFN_KEY=agfn_live_… npx aggregate-finance mcp --url https://app.aggregate.finance/mcp

The same tools are available as a REST API, described at /v1/openapi.json.

What it connects


Banks and cards	Any bank or card through Plaid or SimpleFIN Bridge, plus Mercury, Brex, Ramp and Wise directly
Payments	Stripe (multiple accounts), Square, Shopify, Paddle, App Store, Google Play · PayPal, Lemon Squeezy and Polar when you self-host (coming soon on hosted)
Accounting	QuickBooks, Xero, BILL (bills and payables)
Payroll	Deel, and payroll from Gusto, Justworks and others spotted in your bank data
Cap table	Built in. Imports Pulley’s cap-table export (Pulley shuts down Dec 8, 2026; the import stays for teams moving off it), Carta and Mantle OCX (.xlsx), CSV ledgers and Open Cap Table Format
Investments	Wefunder portfolios (for investors)
Everything else	Statements (CSV, OFX, QFX, QBO), PDFs and photos of receipts, bills sent by email, or just tell your AI
Coming soon	Finch and Rippling: built, and being tested with real accounts

Aggregate only ever reads from your providers and has no way to move money. On hosted, Stripe and Square access is read-only at the source too; QuickBooks offers no read-only option, so Aggregate only calls its read endpoints. Every company you own lives side by side, plus a private Personal space.

NOTE

Aggregate is early. On hosted, Stripe sign-in and the Shopify app are waiting on each provider’s approval; until then, connect Shopify with your own app’s keys. Xero connects up to 5 organizations on hosted until Xero certifies the app. The other connectors are built to each provider’s documentation and are being verified with real accounts. Issues and fixes are very welcome.

How it compares

	Aggregate	One provider’s own MCP server	Personal finance app with AI
Several sources in one place (banks, payments, accounting, payroll, cap table)	✓	One provider	Banks and cards
Several companies side by side, plus personal	✓	One account	Personal
One double-entry ledger, transfers and payouts counted once	✓	—	Varies
Works with any AI that speaks MCP	✓	✓	Usually their own AI
Open source, self-hostable	✓ (AGPL-3.0)	Varies	Rarely
Can move money	Never	Some can	Varies

We also measured it. On our benchmark (100 questions about one made-up company, one model), answers through Aggregate were 100/100 correct. The same model reading tidy exported files with Python got 98/100 and cost less ($0.17 against $0.41). Read the caveats there before quoting it: a two-question gap is within run-to-run noise, Aggregate's tools were tuned on these same questions, and real exports are messier than the ones tested.

Safety

Money is the one place an AI can’t be sloppy, so control is the core of the product, not an add-on.

Your AI can never move money. No payments, no bills paid, no invoices or emails sent. Ever.
Each AI gets its own permission, written as a sentence you can read: which companies, which kinds of data, read only or read and add, and when it expires. Checked on every single request.
Everything is logged and undoable. Every question an AI asks and every record it adds, labeled with who added it. Undo for 30 days, or turn on review so AI changes wait for you. Pause or revoke any AI in one click.
Your secrets stay encrypted. Provider tokens are encrypted with a key kept outside the database (KMS and 1Password supported). Bank logins go through Plaid and are never seen by Aggregate.
Built for prompt injection. Text from documents and memos is treated as untrusted, and a red-team suite of injection attacks runs on every change.
Passkeys (or a code sent by email) are required again before connecting accounts or giving an AI more access.

Read the threat model and security policy.

Run it yourself

Everything is open source, including every hosted feature. Self-hosting needs Node 22.18+ or Docker.

git clone https://github.com/Izzy-Gottz/aggregate-finance && cd aggregate-finance
(umask 077; printf 'AUTH_SECRET=%s\nAGFN_MASTER_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -base64 32)" > .env)
docker compose up -d         # http://localhost:8787

npm install
npm run -s keygen > .env     # -s keeps npm's own output out of the file
npm run build -w @agfn/web
npm start                    # http://localhost:8787

Copy .env somewhere safe, off this machine. Its AGFN_MASTER_KEY encrypts your stored bank tokens and your backups; without it neither can be read. Without email set up, sign-in links print to the server console (docker compose logs agfn). Each connector turns on when its keys are in .env (see .env.example). Postgres or SQLite, Fly.io and Railway configs included. Full guide: self-hosting.

Prefer not to run servers? Hosted Aggregate is the same code, with banking connections, backups and updates handled for you.
