Conditional email rendering in Mastra AI

Use `render_mjml` inside your Mastra AI workflow to generate emails only after specific conditions are met. If a user action triggers an alert, the agent runs the tool to format the notification perfectly. It ensures every automated email is responsive before it hits the delivery queue. If the tool hits a syntax error, the workflow catches it and triggers a retry or notifies the admin.

Multi-step transactional email pipelines

Chain the `render_mjml` tool with other services to build complex email delivery systems. Your Mastra AI agent can generate the content, transpile it, and pass the output to your SMTP provider. This keeps your email logic centralized in your agent's workflow. It makes debugging much easier because you can trace the exact input sent to the renderer.

Human-in-the-loop email review

Set up a workflow where the agent uses `render_mjml` to draft an email, then pauses for your approval. You see the rendered result before the agent sends it out. It adds a layer of safety to your automated communications. You maintain control over the final output while the agent does the grunt work of writing the responsive markup.

Setup guide

Set up MJML (Email Markup) MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All MJML (Email Markup) tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "mjml-email-markup-mcp-client",
  servers: {
    "mjml-email-markup-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "MJML (Email Markup) Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to MJML (Email Markup) tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent MJML (Email Markup) transactions"
);
console.log(result.text);
