How to Use the MailerSend MCP in Vercel AI SDK

Q: Can the Vercel AI SDK read my MailerSend templates?

Yes. The server exposes listemailtemplates. Your agent can fetch the available layouts before generating the email payload.

Stream live email analytics and send transactional messages straight into your Next.js frontend using the Vercel AI SDK.

Stream email stats via MCP Server

Vercel AI SDK shines when you show users live data without loading spinners. Connect this MCP server and your agent can pull delivery metrics right into a React component. It hits `get_date_analytics` and renders the charts instantly. You do not need to build a custom backend dashboard. The agent pulls active domains via `list_sending_domains` and streams the verified status straight to the browser. The user sees exactly what is happening under the hood.

Fire transactional messages live

Users hate waiting for confirmation screens. Your Next.js app can trigger `send_transactional_email` while the AI is still generating the response text. The customer gets the email before they even close the tab. If marketing wants to update the copy, they change it in the dashboard. Your MCP client just calls `send_templated_email` and passes the variables. You never touch the raw HTML.

Expose delivery logs to the user

Support tickets pile up when users complain about missing password resets. Let them debug it themselves. Your setup can run `list_email_activities` and show them exactly why a message bounced. It goes deeper than basic logs. The agent grabs the specific ID and runs `get_message_info` to find out if the recipient actually clicked the link. You get full visibility right in the chat interface.

Setup guide

Set up MailerSend 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 MailerSend 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 MailerSend transactions",
});

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

Common questions about MailerSend MCP in Vercel AI SDK

Install @ai-sdk/mcp. Initialize it with createMCPClient using the HTTP transport, then pass the tools to streamText.

Yes. The server exposes list_email_templates. Your agent can fetch the available layouts before generating the email payload.

The tool execution itself is fast. The SDK streams the resulting text or UI components back to the client as soon as the MCP tool resolves.

The API returns an error to your agent. You can catch this failure and immediately prompt the user for a different address in the chat UI.

It processes raw recipient addresses, email body content, and domain webhooks. The V8 Isolate Sandbox destroys the environment immediately after execution, leaving zero residual data behind.
