How to Use the CFPB Complaints MCP in Vercel AI SDK

Q: How do I connect CFPB Complaints to Vercel AI SDK?

Install @ai-sdk/mcp. Initialize it with createMCPClient({ transport: { type: "http", url: "YOURVINKIUSURL" } }). Pass the resulting MCP tools directly to streamText.

Q: Can Vercel AI SDK stream CFPB Complaints data to React?

Yes. When your agent calls getcomplaint, the resulting JSON streams chunk-by-chunk to the client. Your React components render the financial data instantly.

Q: What happens when the CFPB Complaints MCP Server returns a massive payload?

The SDK handles large responses natively. If searchcomplaints hits hundreds of records, the Vercel AI SDK pipes that data to your frontend without crashing the browser.

Stream live financial complaint data straight into your Next.js frontend with Vercel AI SDK.

Perplexity

Stream CFPB Complaints to the DOM

Your users don't want to stare at a loading spinner while you query 13.8 million records. By passing `search_complaints` to `streamText`, you render financial grievance data the millisecond it hits the wire. The Vercel AI SDK handles the chunking automatically. Build a dashboard that surfaces `get_recent_complaints` directly in your Svelte or Vue interface. Every time a consumer files a new mortgage or credit card dispute, the UI updates instantly without blocking the main thread.

Render Real-Time Narratives

People write long, angry descriptions when banks mess up their money. Use `get_complaints_with_narrative` to fetch those raw stories and feed them to your LLM. Your agent reads the text and extracts the core issue before streaming the summary back to the client. You can filter these stories using `get_complaints_by_state` or `get_complaints_by_product`. If someone disputes a debt collection in Texas, your React component displays the exact company response alongside the consumer's original claim.

Instant Stats and Aggregations via MCP Server

Sometimes you just need the raw numbers without downloading massive payloads. The `get_complaints_stats` tool gives your agent the exact count of issues for a specific financial institution. Pass the MCP Server directly into `mcpClient.tools()` and let the model decide when to pull stats versus full records. Combine this with `get_company_complaints` to build dynamic company profiles. When a user searches for a specific bank, your frontend streams both the total volume of complaints and the most recent individual disputes.

Setup guide

Set up CFPB Complaints 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 CFPB Complaints 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 CFPB Complaints transactions",
});

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