Splitwise for AI agents

Splitwise helps friends, roommates, and travel groups track shared expenses and settle who owes whom, keeping a running balance across a group. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

EVERY SPLITWISE CALL, ON THE RECORD

01 · USE CASES

What agents do in Splitwise.

Add a new shared expense

Create an expense in a group, splitting the cost the way the group has agreed and logging who paid.

Check a group's balance before settling up

Get a group's expenses and current balances so members know exactly what they owe before paying.

Confirm before deleting an expense

Review an expense's details before deleting it, since the deletion changes every member's running balance.

02 · ACTIONS

27 Splitwise actions, graded by risk.

Every Splitwise action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

03 · HOW IT WORKS

Splitwise in three steps.

01Your users connect SplitwiseThey sign in to Splitwise on Arc0 Connect, under your brand, and approve the access you ask for.
02You set the rulesReads run, writes like “create Group” can wait for the user, and “delete Group” can be denied outright.
03Any agent can actYour agent calls Splitwise through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.

POLICY.TS

await arc0.policies.set('splitwise', {
  read: 'allow',
  write: 'ask',        // create_group
  destructive: 'deny',  // delete_group
})

04 · AUTH AND DATA

How Splitwise connects.

Users sign in to Splitwise on Arc0 Connect and approve the scopes you request. Build with Arc0’s Splitwise OAuth app, or bring your own so the Splitwise consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

The same Splitwise connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

Splitwise and Arc0, answered.

Q01

Can I use Splitwise with Claude, ChatGPT or Cursor?

Yes. Connect Splitwise to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Splitwise actions you allow.

Q02

How do users connect Splitwise?

Q03

Which Splitwise actions can my agent take?

27 in total: 12 read, 10 write and 5 destructive, such as “create Group”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Splitwise?

Yes. Actions like “delete Group” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Splitwise too?

Yes. The same Splitwise connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
