How to Use the Minutemailer MCP in Mastra AI

Q: How do I build a retry loop for Minutemailer contact creation in Mastra AI?

Use the Mastra AI workflow engine to wrap the createcontact tool. If the write fails, the system automatically retries the operation using backoff.

Q: Can Mastra AI automatically segment my Minutemailer subscribers?

Yes, you can design a workflow that reads raw contacts via listcontacts and filters them. The MCP setup allows the agent to sort them into specific lists using listsmartlists.

Q: How do I monitor Minutemailer account status with Mastra AI?

You register the getaccountinfo tool within your agent definition. This allows your workflow to check system limits and metadata before triggering heavy email campaigns.

Build self-healing marketing workflows that sync Minutemailer lists and handle API failures using Mastra AI.

Automated List Syncing with Mastra AI

The `list_contact_lists` tool fetches your target audiences to drive conditional marketing workflows. Mastra uses this data to decide whether to route a contact to a main list or a segmented sub-list. If a network hiccup occurs, the built-in workflow engine retries the call with exponential backoff. This ensures your marketing automation never stalls due to temporary API timeouts.

Smart List Event Monitoring

The `list_events` tool tracks account activity to trigger automated follow-ups. The agent evaluates recent actions and branches the workflow based on specific user engagement. You write step-by-step logic that checks `list_smart_lists` to categorize active users. This keeps your segments updated without manual script execution or cron jobs.

Safe Contact Pruning via MCP Server

The `delete_contact` tool removes unsubscribed or bounced emails through your MCP integration. When a workflow identifies a dead address, it triggers the deletion step to maintain list health. To prevent accidental bulk deletions, you can enable human-in-the-loop approval. The Mastra agent halts the execution chain and waits for a manual confirmation before running the tool.

Setup guide

Set up Minutemailer 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 Minutemailer 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: "minutemailer-mcp-client",
  servers: {
    "minutemailer-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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