Splitbill

SplitBill MCP

Split bills and collect payments through PayNow (Singapore) — from the AI you already use.

You paid for the dinner. SplitBill works out who owes what and gives you links to send. Money never passes through us: everyone pays from their own banking app.

• Product page: https://jittee.com/splitbill
• Web app (no sign-up): https://sposched.jittee.com/split/

Features

• Create a split bill from a receipt or a total
• Equal split, or a custom amount for one person (the rest is re-split)
• The person who paid up front is counted but never billed
• Participant management — names optional; payers can enter their own
• Shareable payment URLs (one per amount) + a read-only status link
• PayNow QR on the payment page
• Payment status tracking (self-reported with a transfer screenshot)
• Receipts attached to the total, visible to payers
• 日本語 / English / 中文

Example

User:

Split SGD 891 between 4 people.

AI: creates a SplitBill payment page

SGD 222.75 × 3 participants   (you paid up front, so you are not billed)
Share:  https://sposched.jittee.com/split/pay/?t=…
Manage: https://sposched.jittee.com/split/manage/?t=…   (keep this one to yourself)
Status: https://sposched.jittee.com/split/manage/?t=…   (read-only, safe to share)

Setup

Option A — point your client at the remote server (recommended)

https://jittee.com/mcp/splitbill

That endpoint speaks OAuth 2.1 (dynamic client registration + PKCE), so there is no key to copy around. Connecting opens SplitBill, you enter the PayNow number (or UEN) that should receive the money plus the display name your payers will see in their banking app, and you press allow. The key is created at that moment and kept by your client, and the AI is never asked for your number again.

Claude Code

claude mcp add --transport http splitbill https://jittee.com/mcp/splitbill

Claude Desktop / claude.ai / ChatGPT — Settings → Connectors → add a custom connector and paste the URL. Leave authentication on OAuth.

Smithery — https://smithery.ai/server/jittee/splitbill does the same through its gateway.

Option B — hold the key yourself

For a stdio install, or a client that does not speak OAuth.

Open https://sposched.jittee.com/split/mcp/ and enter the PayNow number (or UEN) that should receive the money, plus the display name your payers will see in their banking app. You get a key that starts with wkn_, shown only once.

⚠️ That key can create pages that collect money to your PayNow. Keep it to yourself. It cannot move money. If you lose it, just create another one.

Claude Code

claude mcp add splitbill --env SPLITBILL_TOKEN=wkn_xxx -- npx -y splitbill-mcp

Any client with a JSON config

{
  "mcpServers": {
    "splitbill": {
      "command": "npx",
      "args": ["-y", "splitbill-mcp"],
      "env": { "SPLITBILL_TOKEN": "wkn_xxx" }
    }
  }
}

Remote, with the key in the URL — for clients that cannot send headers. Choose No authentication, since the key is already in the URL:

https://jittee.com/mcp/splitbill?token=wkn_xxx

Then ask

"Split this receipt four ways. Tanaka did not drink, so $20 for him."

Tools

By default you are treated as the person who paid up front: you count towards the head count, but no payment link is created for you. Pass i_paid: false to turn that off.

Environment

Good to know

• No sign-up, no login. The key is the only credential.
• Money never passes through us. Payments go directly between banking apps over PayNow. SplitBill only shows the amount and the recipient, and records who says they have paid.
• Pages delete themselves 7 days after the last payment, images included.
• NRIC cannot be used as a PayNow recipient (Singapore PDPA); mobile number or UEN only.
• Amounts are SGD.
• Anyone can create a split page, so payment pages carry a standing warning and a report button. Never send money from a link you got from someone you do not know.
