How to Use the Fee Navigator MCP in Vercel AI SDK

Q: Can I use Vercel AI SDK to compare multiple merchant statements with Fee Navigator?

Yes. You can chain calls using listmerchants to grab the target accounts, then run uploadstatement on each file. The SDK handles these parallel tool calls and updates your frontend state as each audit finishes.

Stream real-time merchant fee analysis directly into your Next.js UI using Vercel AI SDK and this MCP Server.

Live Statement Auditing in Vercel AI SDK

Stop making users stare at a blank loading screen while processing complex merchant statements. With this MCP Server, your app streams live processing fee updates straight to the browser. Your code calls `upload_statement` and the parsed data renders instantly, chunk by chunk, in your custom React components. The client triggers `analyze_statement` to parse interchange rates and markup fees on the fly. Because the token identity is verified instantly via `get_me`, your users see their true savings potential unfold on screen without a single page refresh.

Instant Savings Proposal Generation

Building a merchant portal requires fast feedback, and this setup delivers it. Your AI client pulls raw data using `get_proposal` and populates your interactive UI tables in real time. Users can compare their current rates with benchmark averages by invoking `get_industry_stats`. The Vercel AI SDK handles the raw JSON stream, converting complex payment processor markups into clean, readable comparison charts.

Direct Merchant Profile Management

Let your users manage their processing accounts without navigating legacy dashboards. Your application queries `get_merchant` to render current profile data directly inside your React state. When users need to verify historical audits, the agent calls `list_audits` to fetch the complete log. This direct connection keeps your database light and your frontend fast.

Setup guide

Set up Fee Navigator 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 Fee Navigator 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 Fee Navigator transactions",
});

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

Common questions about Fee Navigator MCP in Vercel AI SDK

It connects via the standard HTTP transport to push real-time data back to your application. When you call `analyze_statement`, the tool outputs structured chunks that the SDK feeds directly into your UI stream.

Yes. You can chain calls using `list_merchants` to grab the target accounts, then run `upload_statement` on each file. The SDK handles these parallel tool calls and updates your frontend state as each audit finishes.

Yes. The integration runs entirely over standard HTTP, making it fully compatible with Vercel Edge Functions. You get fast execution and zero cold-start penalties when running `get_account_info` on the edge.

You configure the SDK transport with an authProvider to supply the correct token. This token maps directly to `get_me` to verify permissions before any financial data is accessed.

Your uploaded PDF merchant statements and transaction fee audits are processed inside Vinkius's secure sandbox. No raw financial statements are stored permanently, and the data is encrypted during transit to prevent exposure of sensitive merchant account numbers.
