Automate Customer.io Sequences in Mastra AI

Chain `list_active_campaigns` and `dispatch_broadcast` to run complex marketing sequences. The agent decides when to fire these based on your workflow rules. Mastra AI handles the retries if the network blips. Your logic stays clean while the agent manages the sequence.

Conditional Logic for Customer Lists

Use `list_segment_members` to filter your audience before taking action. You build loops where the agent checks a list and updates profiles one by one. The workflow engine manages the execution flow. It keeps your operations running even if you have thousands of records to process.

Handle Transactional Messaging Failures

Set up a fallback path using `send_transactional_email` within your agent workflows. If a primary step fails, the workflow catches it and triggers a notification. You define the rules for when to retry. It gives you control over your messaging reliability.

Setup guide

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

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

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

Common questions about Customer.io MCP in Mastra AI

Import the MCP client into your Mastra agent config. You spread the tools into the agent definition so the workflow engine can call them.

You can enable tool approval for sensitive actions like sending emails. This forces the agent to wait for your sign-off before running the task.

You add the `get_connection_status` tool to a recurring agent task. It pings the API to make sure everything is working as expected.

Mastra AI handles the backoff logic. If a tool call fails, the agent uses the framework's retry settings to try again later.

We use a zero-trust sandbox for all tool calls. Your user contact lists and email logs stay strictly within the encrypted memory space.
