How to Use the Campaign Monitor MCP in Mastra AI

Q: Can I use this to clean my subscriber lists?

You can build a workflow for it. Your agent could listsubscribers, check each one against an external data source (like your CRM) to see if they are still active customers, and then flag inactive ones for removal.

Perplexity

Create Unbreakable Reporting Jobs

Automate your end-of-month reporting. A Mastra AI workflow can `list_clients`, loop through them to `list_campaigns`, and then fetch the results for each one with `get_campaign_performance`. You get a complete report without lifting a finger. The real advantage is Mastra's resilience. If an API call to the MCP server times out, the engine retries it automatically with exponential backoff. Your reporting workflows will run successfully even if network conditions are spotty.

Use Logic for Smarter List Management

Go beyond simple automation with conditional logic. You can build a workflow that uses `list_subscribers` to check if a contact already exists on a list. If they don't, the agent calls `add_subscriber`; if they do, it can trigger a different action, like updating their record in a CRM. This MCP server provides the actions, and Mastra AI provides the brain. You can construct complex processes, like 'if adding a subscriber fails, send a Slack notification and add the contact to a manual review queue.' It's powerful automation with guardrails.

Sync Campaign Monitor Data Reliably

Keep your internal systems up-to-date. Set up a recurring Mastra AI workflow to fetch all your contact lists with `list_contact_lists` and then pull all active contacts with `list_subscribers`. The agent can then sync this data into your own database. For sensitive operations, you can require a human in the loop. Before your agent adds a large batch of new subscribers, the workflow can pause and wait for your approval via Mastra's `requireToolApproval` feature. You get automation with control.

Setup guide

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

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

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

Common questions about Campaign Monitor MCP in Mastra AI

You install the Mastra MCP client and provide your Vinkius URL for the Campaign Monitor server. Mastra AI automatically discovers the available tools, like `add_subscriber` and `list_campaigns`, making them available to your agents.

Yes, that's what Mastra AI is designed for. You can chain tools together, for example: `list_clients` -> `list_campaigns` -> `get_campaign_performance`. The workflow engine manages the state and execution order for you.

Mastra AI's workflow engine will automatically retry the failed tool call. It uses an exponential backoff strategy to avoid overwhelming the API, making your automation much more reliable than a simple script.

You can build a workflow for it. Your agent could `list_subscribers`, check each one against an external data source (like your CRM) to see if they are still active customers, and then flag inactive ones for removal.

Your data is only in memory during the workflow execution. Mastra AI streams data from the Vinkius MCP server, which processes your subscriber and campaign information in a secure, single-use environment. Once the workflow is done, the data is gone.
