Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.
Your AI does the work. We keep it safe and sound.
No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.
Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

Each Connector runs inside its own sealed environment.
Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.
One switch stops every agent. Instantly.
One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.
Spending limits that pause instead of surprise.
Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.
Three controls, built into the layer your AI connects through.

Le ChatBuilding your own app? The connector is yours to use.
You don't need a client to put Splitwise to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

It does not authenticate your account with Splitwise. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

FAQ
Questions Splitwise owners ask.
- 01
How do I connect my Splitwise account?
You need to generate a personal API token from your Splitwise Developer Applications settings and then add that key to the Vinkius vault.
- 02
Which AI clients can use this MCP?
You can use this with any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.
- 03
Can I split expenses by percentage?
Yes, you can instruct your AI agent to apply custom or percentage-based splits when creating an expense.
- 04
Is my Splitwise data secure?
Vinkius manages your credentials securely in a vault, so your API key is only used to facilitate the connection between your agent and Splitwise.
- 05
Do I need to use the Splitwise app to see changes?
No, once the AI agent creates or deletes an expense, the changes are reflected immediately in your Splitwise account.
- 06
Can the agent distribute the bill unequally?
Yes! When creating an expense, the AI agent can pass detailed users configuration in JSON to specify exact dollar amounts for each involved party.
- 07
How far back does the expense log go?
The agent typically limits the reading to the 20 most recent expenses to keep memory manageable, but can be instructed to pull earlier ones.
- 08
Can the bot settle debts?
Currently, the agent interacts with expenses. To log a debt settlement, the agent submits a specific 'payment = true' expense wrapper via the splitwise schema.
