Automated email workflows in Mastra AI

Trigger complex agent actions based on parsed email content. Use `parse_eml_file` within your Mastra workflow to extract key data points like dates and sender addresses for downstream logic. This allows you to automate responses or sorting tasks based on the actual body of the email. You can define conditional branches that execute only after the parser confirms the email format is valid.

Robust error handling for Mastra AI agents

If an email file is malformed, your Mastra agent can catch the error and retry or notify an admin. The `parse_eml_file` tool provides predictable output that fits right into your workflow state machine. Avoid the headache of manual string manipulation. Let the server handle the heavy lifting while your agent focuses on the decision-making process.

Deploy email parsing agents with Mastra AI

Configure your agents to use this MCP server for all incoming document tasks. Whether you are running locally or in the cloud, the agent will access the file system via the standard MCP interface. You can set up tool approval steps to ensure humans verify the extracted data before the agent proceeds. It gives you full control over how your automated processes interact with your local files.

Setup guide

Set up Email (.eml) File Parser 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 Email (.eml) File Parser 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: "email-eml-file-parser-mcp-client",
  servers: {
    "email-eml-file-parser-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent Email (.eml) File Parser transactions"
);
console.log(result.text);
