Real-time Account Creation via Vercel AI SDK and MCP

`increase_create_account` spins up a new commercial bank account programmatically right inside your application flow. Your frontend gets the raw account details instantly, bypassing the usual manual onboarding delays. This means your users watch their new accounts appear live on screen. You bypass loading spinners entirely by piping the JSON payload directly into your React components.

Instant Card Issuance and Routing Setup

`increase_create_card` generates active debit cards linked to your newly created accounts on demand. You pair this with `increase_create_routing_number` to assign unique routing details for incoming deposits. The system outputs clean data objects that your UI renders immediately. Customers get their virtual card numbers and routing details without waiting for background batch processes to finish.

Live Ledger Audits and Balance Checks

`increase_get_balance` pulls the exact ledger balance for any account in your program. You feed this data to `increase_list_transactions` to display a clean feed of settled and pending ledger movements. Your app displays real-time financial states directly in the user dashboard. No stale data, no polling, just direct ledger access.

Setup guide

Set up Increase 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 Increase 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 Increase transactions",
});

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

Common questions about Increase MCP in Vercel AI SDK

You connect the two systems using the Vinkius endpoint token. Once configured, your app executes bank transfers and account queries without intermediate backend servers slowing down the response.

Yes. You call the balance tool and stream the JSON payload straight to your frontend components. The UI updates the numbers as soon as the ledger records the change.

Install the required packages and initialize the client with your Vinkius HTTP URL. Pass the tools directly to your text generator function and remember to close the connection when finished.

Use the built-in simulation tools in your sandbox environment. You trigger mock deposits and wires to verify your application logic before moving real funds.

Vinkius runs every request inside an isolated, zero-trust sandbox environment. Your routing numbers and transaction history never persist on the host server, keeping your banking credentials completely isolated.
