Build self-healing email workflows in Mastra AI

Use `create_contact` within a Mastra agent to ensure new signups are processed even if the network blips. The workflow engine handles retries if the API is busy. Your agent manages the state of the signup process. If a step fails, it triggers your defined recovery logic immediately.

Conditional list management with this MCP Server

Create logic branches that use `list_lists` to decide where to add a subscriber. It keeps your segmentation accurate without human oversight. You define the rules, and the agent executes the tool calls. It’s perfect for routing high-intent leads to specific VIP lists.

Execute complex campaign tasks with Mastra AI

Chain `get_campaign` and `update_contact` to automate your follow-ups. You can set the agent to monitor specific campaigns and adjust contacts based on their activity. The framework tracks every step of the workflow. You maintain full control over the execution flow while the MCP Server handles the API interaction.

Setup guide

Set up Get a Newsletter 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 Get a Newsletter 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: "get-a-newsletter-mcp-client",
  servers: {
    "get-a-newsletter-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Get a Newsletter MCP in Mastra AI

It does. You just import the MCP client into your agent definition and spread the tools into the agent's toolset.

Yes. Mastra has a built-in workflow engine that handles retries for any tool call, including those used for list management.

The agent treats the tools as native functions. It saves the results of your list or contact queries into its memory for subsequent steps.

The MCP Server returns an error that Mastra catches. You can then define a fallback branch to handle the issue gracefully.

Vinkius routes your requests over an encrypted channel. The MCP Server acts as a proxy, so your local machine never stores sensitive contact records.
