How to Use the Mailchimp MCP in Mastra AI

Q: How do I add this MCP Server to Mastra AI?

Install the latest @mastra/mcp package and initialize a new MCPClient. Pass your server URL, then call mcpClient.listTools() to spread the operations into your agent's configuration.

Q: Can Mastra AI search for specific Mailchimp subscribers?

Yes. The searchmembers tool finds contacts across all your audiences by name or email. Your workflows can use this to verify a user exists before attempting to update their preferences.

Q: How do I retrieve performance stats for a Mailchimp campaign?

Pass the getreport tool to your agent. It will fetch open rates, click metrics, and bounce data. You can then pipe that data into a Slack notification or a reporting dashboard.

Sync Mailchimp contacts with Mastra AI

`list_members` and `add_member` form the backbone of your audience management pipelines. Mastra AI can fetch your current subscriber base, compare it against an external database, and push missing records automatically. If an API call fails, the framework's built-in exponential backoff tries again. You dictate exactly how the workflow handles bad data. Set up conditional branching to tag bounced emails or clean dead contacts. The MCP Server runs these hygiene tasks reliably in the background without manual oversight.

Draft and configure email campaigns

`create_campaign` lets your agent draft entire newsletters from scratch. You can build a workflow that scrapes a blog, summarizes the posts, and generates an email draft. The tool returns the new campaign ID for the next step in your sequence. Before anything goes out, you can run `get_campaign` to verify the merge fields and subject lines. This MCP Server handles the payload formatting while your workflow engine manages the execution logic.

Enforce approvals on live sends

`send_campaign` fires emails to real people immediately. Because this action is permanent, you can use the `requireToolApproval` flag in your setup. The agent will pause the workflow and wait for a human to click approve before triggering the send. This keeps your marketing velocity high while preventing disastrous automated mistakes. You get the speed of AI drafting combined with the safety of manual verification.

Setup guide

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

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

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