How to Use the LendAPI MCP in Vercel AI SDK

Q: Can the Vercel AI SDK handle LendAPI authentication?

Yes, you use the authProvider to inject your credentials. This keeps your keys out of the client-side code while maintaining a secure connection to the server.

Stream LendAPI data directly into your Vercel AI SDK interface. Stop waiting for spinners and show live credit decisions.

Perplexity

Real-time loan application streaming

Pipe `create_loan_application` results straight to your frontend components. You get live updates as the server processes each field without forcing your users to stare at a loading state. Your UI reacts instantly when `submit_loan_application` pushes data through the stream. It turns a standard backend operation into a responsive experience that feels native to your React or Next.js app.

Dynamic borrower profile management

Fetch and display borrower data with `get_borrower_details` inside your AI agent's flow. You can pull specific profiles on demand as the user interacts with your chatbot interface. Use `get_lendapi_picklists` to populate your input forms dynamically. This keeps your dropdowns synced with the source of truth so your users never submit invalid data.

Efficient data listing for Vercel AI SDK

List existing records using `list_borrowers` and `list_loan_applications` to populate your dashboard widgets. It keeps the data layer thin and fast for Edge Function deployments. Your agent handles the heavy lifting by querying the MCP server directly. This reduces the need for custom API middleware in your own codebase.

Setup guide

Set up LendAPI 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 LendAPI 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 LendAPI transactions",
});

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

Common questions about LendAPI MCP in Vercel AI SDK

Install the MCP packages and instantiate the client using the provided endpoint. Pass the tools from the `mcpClient` directly into your `generateText` or `streamText` function calls.

Yes, you use the `authProvider` to inject your credentials. This keeps your keys out of the client-side code while maintaining a secure connection to the server.

It does. Because the server follows the MCP standard, the tools return data that the Vercel AI SDK handles as standard tool outputs, allowing for immediate UI updates.

Wrap your tool calls in standard try-catch blocks within your agent logic. Since you control the execution, you can surface specific error messages to the user immediately.

Data remains encrypted in transit between your environment and the server. The connection uses your unique endpoint token, ensuring only your authorized agent accesses borrower PII.
