How to Use the Klaviyo MCP in Vercel AI SDK

Q: Can I use Vercel AI SDK to trigger automated flows in Klaviyo?

Yes, you can. Your agent uses listautomatedflows to identify active marketing sequences and then triggers them by dispatching custom events with trackevent.

Q: How do I fetch tracking metrics using this server?

Use the listmetrics tool to retrieve raw engagement data. Your agent can then parse these metrics to feed live charting libraries inside your Next.js dashboard.

Q: How does Vercel AI SDK secure my customer profiles and event data?

All customer profiles accessed via getprofile are processed in an ephemeral V8 sandbox. No marketing data is cached or stored on Vinkius servers, ensuring complete compliance with your existing privacy policies.

Build real-time marketing dashboards that stream Klaviyo customer profiles and event metrics directly into your Vercel AI SDK frontend.

Perplexity

Stream customer events to Vercel AI SDK instantly

The `track_event` tool records live customer interactions directly from your edge-rendered interface. When a user clicks a button, your Vercel AI SDK interface captures the action and updates the UI state without waiting for a backend response cycle. You get instant verification of event delivery. Your users see their updated activity feed immediately, removing the lag associated with traditional marketing tracking setups.

Render live Klaviyo segments in your Vercel AI SDK app

The `list_segments` tool fetches dynamic customer cohorts to feed your real-time React or Next.js components. This MCP Server lets your agent pull fresh audience definitions and render them in a streaming UI as the data arrives. Instead of staring at loading spinners, your marketing team sees segment sizes and member counts compile line-by-line. You can combine this with `list_profiles` to display individual profile details on the fly.

Inspect and preview email templates on the edge

The `list_email_templates` tool retrieves your saved newsletter layouts directly into your Vercel AI SDK streaming chat interface. Your marketing agent can pull these templates, swap variables, and show live previews to your content team. This MCP setup keeps your design review process fast, running entirely within your edge-rendered application. Coupling this with `list_campaigns` allows your team to inspect previous layout performance metrics side-by-side.

Setup guide

Set up Klaviyo 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 Klaviyo 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 Klaviyo transactions",
});

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