How to Use the Splitwise MCP in Vercel AI SDK

Q: Can Splitwise handle complex groups using ai-sdk?

Yes. You can use the getgroups tool to list all relevant groups and then pull data for each one individually. This makes tracking large, multi-person expenses straightforward in your frontend.

Q: If I use Splitwise with ai-sdk, can I delete expenses?

Absolutely. The deleteexpense tool lets your agent remove specific transactions from a group's history. This is useful if someone made an entry in error and needs it wiped clean.

Q: How do I check my balance with Splitwise using ai-sdk?

You can list all expenses using getexpenses and then process the results stream to calculate the current net debt. The real-time nature of the ai-sdk makes this calculation visible to the user instantly.

Real-time expense tracking.

The `create_expense` tool lets you record a new shared cost, and those updates appear immediately in your UI. You don't wait for a spinner; the data flows right into place.

Fetch live user details.

Need to know who paid what? Call `get_user` or `get_friend` to pull current account details instantly. This is great when you need precise, up-to-the-second info for your app's state.

Monitor group finances live.

Use `get_group` to check the status of a whole shared pot. You can monitor all transactions by calling `get_expenses`, watching every entry stream in as it hits the system. It's perfect for building dynamic dashboards.

Setup guide

Set up Splitwise MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all Splitwise tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent Splitwise transactions",
});

console.log(text);
await mcpClient.close();
