How to Use the EasySendy MCP in Mastra AI

Q: How do I view all EasySendy lists in Mastra AI?

Use the listalllists tool. The agent retrieves the current inventory of lists and stores them in its memory for subsequent tasks.

Perplexity

Automated subscriber workflows

Chain `create_list` and `add_subscriber` into your Mastra agent pipelines. If a list creation fails due to a network glitch, the workflow engine triggers a retry automatically. This gives you a predictable path for onboarding new users. Your agents follow the steps you define without needing manual intervention.

Conditional email list hygiene

Use `unsubscribe_user` within a branching logic block to clean your lists based on bounce events. Your workflow checks the subscriber status and acts before the next campaign goes out. It prevents you from burning your reputation on invalid addresses. The agent handles the cleanup based on the conditions you set in your workflow file.

Data-driven list updates

Query `get_subscriber_details` to feed data into your decision agents. If a subscriber profile matches your criteria, the agent executes an `update_subscriber` task. This keeps your segments accurate. You aren't just sending emails; you're maintaining a precise record of your audience.

Setup guide

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

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

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