Splitwise MCP with Claude: Automate Shared Expense Tracking and Settle-Ups

The short answer

Claude works with Splitwise through the Model Context Protocol, an open standard that acts as a secure adapter. Once connected with the sign-in method you approve, Claude can read group balances, add expenses, split costs and help settle up, using permissions your organisation controls.

What is Splitwise?

Splitwise is an app that helps people split bills and shared expenses with friends, family, roommates and colleagues. It tracks who paid what, calculates who owes whom, and helps groups settle up so everyone stays on the same page. Finance teams, operations staff and small businesses also use shared expense tracking for team outings, client dinners, travel and shared office costs.

How Claude connects to Splitwise through MCP

The Model Context Protocol, or MCP, is an open standard that lets Claude use other software securely. Think of it as a universal adapter between Claude and a tool like Splitwise. The organisation decides exactly what Claude can see and do, and access can be withdrawn at any time.

Once Splitwise is connected, Claude can typically read groups, fetch current balances, look up past expenses and add new ones. A staff member can simply describe a shared cost in everyday words, such as splitting a team lunch three ways, and Claude can record it in the right group with the correct split.

Permissions and approvals keep people in charge. Access can be limited to specific groups, and consequential actions such as recording large payments or settling balances can require a person to confirm first. Every action can be logged so the team has a clear record of what was done and by whom.

What you can automate

  • Team travel expense splitting

    After a business trip, a team member can ask Claude to add hotel, taxi and meal costs to the trip group and split them according to agreed rules. Claude can then show who owes what, so the finance team does not have to chase receipts across several inboxes.

  • Client entertainment tracking

    Sales staff often pay for client dinners and then need to share the cost with colleagues. Claude can record these costs in a shared group with the right split and attach a short note about the client, making it easier to reconcile later against approved entertainment budgets.

  • Monthly shared office costs

    Teams that share a kitchen, subscriptions or meeting room supplies can have Claude add recurring costs each month and report the running balance. Office managers can review the totals without building a spreadsheet by hand.

  • Balance checks before payroll or reimbursements

    Before a payroll run or expense reimbursement cycle, a finance manager can ask Claude to fetch outstanding group balances across several projects. The summary helps identify who still needs to settle up and highlights unusual amounts for a person to review.

  • Event and offsite cost coordination

    For company offsites, Claude can help the organiser record venue, catering and transport payments as they happen, keeping a live view of total spend per attendee. This reduces end-of-event disputes about who paid for what.

An end-to-end workflow: Monthly team expense settlement

TriggerAt the end of each month, the operations lead asks Claude to prepare the shared team expense settlement.

  1. Claude fetches all open expenses and current balances from the team's Splitwise groups.

  2. Claude checks each new expense against the expense codes and approved split rules agreed by the team.

  3. Claude flags any unusually large amounts or unclear splits and sends them to the operations lead for approval.

  4. Once approved, Claude records the agreed settlements and produces a summary of who owes whom.

  5. The summary is passed to the finance system for matching against the company's expense records and payroll adjustments.

  6. Each action is logged, so the finance team has a full audit trail.

OutcomeTypically, the month-end settlement takes far less time, balances are reconciled with fewer queries, and the finance team has a clear, approved record of every shared cost.

How we set it up

  1. Book a free automation audit

    We review how your team currently splits and tracks shared costs, and identify the workflows worth automating with Claude and Splitwise.

  2. Choose the sign-in method

    We connect Splitwise using OAuth sign-in, which lets each user approve access, or an API key for a controlled service account, depending on your security policy.

  3. Design the workflow

    We map the end-to-end process across Splitwise and your other systems, such as Microsoft 365, your CRM, ERP or ticketing tool, and agree which actions need human approval.

  4. Test and launch with monitoring

    We test the workflow against real past expenses, then launch with monitoring, audit logs and clear escalation paths.

  5. Train your team

    We train the people who will use Claude day to day, so they know how to ask for what they need and how to review what Claude prepares.

Frequently asked questions

What does the Splitwise MCP server do?

The Splitwise MCP server acts as a secure bridge between Claude and your Splitwise account. It allows Claude to read groups and balances, add expenses and help settle up, within the access you grant. It does not give Claude unrestricted control over your account, and you decide which actions are permitted.

Is connecting Splitwise to Claude secure?

Security depends on how the connection is designed. We use the sign-in method Splitwise supports, either OAuth sign-in or an API key, and apply least-privilege access. Consequential actions can require human approval, and every action can be logged for review.

What can Claude do with Splitwise once connected?

Typically, Claude can fetch group balances, list recent expenses, add new expenses with a chosen split, and help settle up through natural language requests. The exact actions available depend on the access permissions you set during design.

How long does setup take?

Setup time depends on how many groups, workflows and other systems are involved. A simple connection for one team can often be designed and tested within a few weeks. We confirm a realistic timeline during the free automation audit.

What plan or permissions do I need?

You generally need a Splitwise account that can authorise access through OAuth sign-in or generate an API key, and permission to use those groups. Requirements can vary, so we confirm the exact account setup and permissions with you during the audit.
