Submit bulk lists from your Vercel AI SDK UI

Calling the `validate_bulk` tool kicks off the cleaning process the moment a user uploads a CSV in your Next.js app. Instead of making them stare at a blank screen, your agent passes the raw contacts to the API and immediately returns a tracking ID. You wire this directly into the streaming text response. The user gets immediate feedback that the job started, keeping the interface snappy while the heavy lifting happens in the background.

Stream bounce data directly to the user

Running the `get_validation_status` tool takes that tracking ID and pulls the final validation results. Your AI client reads the exact bounce reasons, spam trap warnings, and syntax errors straight from the endpoint. Because Vercel handles the streaming state, you render these results into your Svelte or React dashboard in real-time. Developers build a live progress bar without writing custom polling logic.

Connect the No2Bounce MCP Server

Setting up this MCP Server requires just the official package and a standard HTTP transport configuration. You pass the endpoint URL to the client creator and immediately expose both tools to your application. Extracting the definitions hands them over to your agent. Just remember to close the connection when the edge function finishes its streaming cycle.

Setup guide

Set up No2Bounce 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 No2Bounce 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 No2Bounce transactions",
});

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

Common questions about No2Bounce MCP in Vercel AI SDK

Install the MCP package and initialize it with your transport settings. Point the HTTP transport to your Vinkius endpoint.

Yes. You trigger the job with the bulk tool, then stream the status checks back to the UI. The user sees the clean count update live.

Your agent handles the logic. It grabs the tracking ID and checks the status tool until the final list is ready.

No. The standard runs these operations asynchronously. Your function stays responsive while the external service cleans the contacts.

The system processes your raw email addresses in an ephemeral V8 isolate sandbox. Once the tracking ID expires and the final bounce metadata returns to your frontend, the memory drops. Nothing persists after the connection closes.
