Klaviyo Integration

The Klaviyo integration provides access to manage Klaviyo accounts, profiles, lists, segments, campaigns, and metrics through the Integrate MCP server.

Installation

The Klaviyo integration is included with the SDK:

import { klaviyoIntegration } from "integrate-sdk/server";

Setup

1. Create a Klaviyo OAuth App

1. Create an OAuth application for Klaviyo
2. Configure your redirect URI
3. Note your Client ID and Client Secret

2. Configure the Integration on Your Server

Add the Klaviyo integration to your server configuration. The integration automatically reads KLAVIYO_CLIENT_ID and KLAVIYO_CLIENT_SECRET from your environment variables:

import { createMCPServer, klaviyoIntegration } from "integrate-sdk/server";

export const { client: serverClient } = createMCPServer({
  apiKey: process.env.INTEGRATE_API_KEY,
  integrations: [
    klaviyoIntegration({
      scopes: ["accounts:read", "profiles:read", "profiles:write", "lists:read", "lists:write", "campaigns:read", "campaigns:write", "metrics:read"], // Optional
    }),
  ],
});

You can override the environment variables by passing explicit values:

klaviyoIntegration({
  clientId: process.env.CUSTOM_KLAVIYO_ID,
  clientSecret: process.env.CUSTOM_KLAVIYO_SECRET,
      scopes: ["accounts:read", "profiles:read", "profiles:write", "lists:read", "lists:write", "campaigns:read", "campaigns:write", "metrics:read"], // Optional
});

3. Client-Side Usage

The default client automatically includes all integrations. You can use it directly:

import { client } from "integrate-sdk";

await client.authorize("klaviyo");
const result = await client.klaviyo.listAccounts({});

console.log(result);

If you're using a custom client, add the integration to the integrations array:

import { createMCPClient, klaviyoIntegration } from "integrate-sdk";

const customClient = createMCPClient({
  integrations: [klaviyoIntegration()],
});
