How to Use the Customer.io MCP in Vercel AI SDK

Q: What happens if the Customer.io API is down?

The getconnectionstatus tool tells you the current health. You can handle the error in your UI code before the agent tries a request.

Stream Customer.io campaign data and user profiles directly into your Vercel AI SDK frontends for real-time UI updates.

Live Customer.io Data in Vercel AI SDK

Feed your UI with live campaign metrics using `get_campaign_performance` and `list_active_campaigns`. Your React components render the state changes as the agent fetches them. This MCP Server pushes results through the stream, so your users see the actual numbers without waiting for a backend request to finish. It keeps the Vercel AI SDK interface snappy.

Manage User Profiles via TypeScript

Call `get_customer_details` or `list_segment_members` to pull specific user data into your application state. It handles the API handshake so you focus on the frontend logic. You avoid the boilerplate of manual fetch calls. The typed results map cleanly to your existing TypeScript interfaces.

Trigger Transactional Messages

Send individual emails using `send_transactional_email` directly from your serverless functions. It connects your app logic to your messaging stack. The tool execution happens during the stream, allowing your frontend to confirm the action immediately. It makes status updates effortless for your end users.

Setup guide

Set up Customer.io 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 Customer.io 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 Customer.io transactions",
});

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