How to Use the Maileroo MCP in Vercel AI SDK

Q: How do I connect Maileroo to the Vercel AI SDK?

Run npm install ai @ai-sdk/mcp. Configure your MCP client with the HTTP transport URL and pass the resulting tools into streamText. Always call mcpClient.close() when the stream finishes.

Q: Can my Vercel AI SDK app send emails automatically with Maileroo?

Yes. Your AI client uses sendtransactionalemail to dispatch messages based on user prompts. You control the exact trigger logic inside your frontend components.

Q: How do I check bounce rates through the AI client?

Ask your agent to run listsendingactivity. It pulls the recent delivery logs and streams the specific failure reasons straight back to your user interface.

Stream live email delivery status and transactional templates directly into your React app using the Vercel AI SDK.

Build live email dashboards in Vercel AI SDK

Maileroo delivers transactional emails fast, and your users hate waiting for confirmations. Using the Vercel AI SDK, your agent calls `list_sending_activity` and streams the exact delivery logs straight into your Next.js frontend as they happen. No loading spinners. Just raw data appearing instantly. You skip building a custom polling mechanism entirely. The MCP server handles the API connection while your frontend renders the exact timestamp a message hit an inbox.

Trigger templates from the edge

Next.js edge functions execute instantly, and your transactional emails should match that speed. Your AI client grabs available layouts using `list_email_templates` and immediately fires off a payload via `send_transactional_email`. A customer clicks buy, your agent processes the request, and the receipt hits their inbox. You bypass the entire backend routing layer because the Vercel AI SDK talks directly to the mail provider.

Monitor infrastructure via this MCP Server

Internal admin panels usually eat up days of API wiring. Connect this tool to your frontend setup, and your internal dashboard instantly queries `list_configured_webhooks` to show where bounce events go. When a sending domain drops offline, your agent catches it. It pulls the status with `get_domain_details` and renders the error right in your React UI before support tickets start piling up.

Setup guide

Set up Maileroo 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 Maileroo 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 Maileroo transactions",
});

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

Common questions about Maileroo MCP in Vercel AI SDK

Run `npm install ai @ai-sdk/mcp`. Configure your MCP client with the HTTP transport URL and pass the resulting tools into `streamText`. Always call `mcpClient.close()` when the stream finishes.

Yes. Your AI client uses `send_transactional_email` to dispatch messages based on user prompts. You control the exact trigger logic inside your frontend components.

The MCP standard works perfectly at the edge. Your serverless functions call `list_sending_domains` or check templates without cold start delays.

Ask your agent to run `list_sending_activity`. It pulls the recent delivery logs and streams the specific failure reasons straight back to your user interface.

Maileroo processes recipient email addresses, sender domains, and message bodies. Vinkius runs the connection in an ephemeral V8 Isolate Sandbox, meaning your API tokens and payload data vanish the second the execution finishes.
