Arcle in your AI apps

Connect Arcle to the AI app you already use — Claude, ChatGPT, Cursor — and it can read your account and draft payments for you. Ask “what did I spend this week?” in the middle of whatever else you're doing, and get a real answer from your real balance. It's the same account and the same money as the app: nothing is copied anywhere, and you decide what each app is allowed to see.

Your AI can never move your money

No connected app can send funds — not with the wrong prompt, not if someone else gets hold of it. The most it can do is prepare a payment and hand you a link. You still approve it in Arcle with Face ID, your fingerprint, or your PIN. Your biometric and PIN never reach the AI app.

Connecting an app

1
Open AI connections

In Arcle, go to Settings → Security → AI connections.

2
Tap “Connect an AI app”

Give it a name you’ll recognise later, like “Claude Desktop” or “work laptop”. If you connect three apps, this is how you tell them apart.

3
Decide if it can draft payments

Leave the box unticked and the app is strictly read-only. Tick it and the app may prepare payments for you to approve — it still cannot send anything.

4
Confirm with your PIN

The same 4-digit Arcle PIN you use for transfers. This stops anyone who borrows your unlocked laptop from quietly creating a key.

5
Copy your key

It’s shown once and never again — we only keep a scrambled copy, so we couldn’t show it to you twice even if you asked. Paste it straight into your AI app. Lost it? Just delete that connection and make a new one.

Setting up your app

Wherever an app asks for a server address, Arcle's is:

https://arcle.xyz/api/mcp

ChatGPT

Easiest of the three — you don't need a key at all. Add Arcle as a connector using the address above and ChatGPT will send you to Arcle to sign in and approve it, the same way you'd connect any other account. You can skip the steps above entirely.

Claude Desktop

Settings → Developer → Edit Config, then add Arcle under mcpServers with your key:

{
  "mcpServers": {
    "arcle": {
      "url": "https://arcle.xyz/api/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_KEY_HERE"
      }
    }
  }
}

Claude Code / Cursor

One command in your terminal:

claude mcp add --transport http arcle https://arcle.xyz/api/mcp \
  --header "Authorization: Bearer YOUR_KEY_HERE"

What to try first

Start here

Ask “what's my Arcle balance?”. If it answers with your real numbers, you're connected. That one question is the whole test.

Ask about your money

“What did I spend last week?”, “who have I sent money to recently?”, “show my unpaid invoices”, “how are my pools doing?” — it reads your account and answers in plain language.

Draft a payment

If you allowed it, try “send $1 to @someone”. You'll get a link back rather than a sent payment — open it and Arcle asks for Face ID or your PIN. That extra tap is the whole safety model, and it's deliberate.

Disconnect anytime

Settings → Security → AI connections lists every connected app and when it was last used. Remove one and it stops working immediately. Do this first if a laptop goes missing.

Good to know

  • Connections expire after 90 days on their own, so one you forget about doesn't live forever.
  • Connect as many apps as you like — each gets its own key, and removing one leaves the others working.
  • A read-only connection can see balances and history but can't draft payments. If you're only curious, start there.
  • Your key is like a password: anyone holding it can read your account, so don't paste it into a shared document or a chat. It still can't move money.
  • Setting up a brand-new Arcle account still happens in the app — see Getting Started.
