How to Use the Emma MCP in Mastra AI

Q: Does Mastra AI support tool approval for Emma?

Yes, you can set requireToolApproval: true for any Emma tool. This forces a human-in-the-loop check before the agent performs actions like creategroup.

Build resilient email workflows in Mastra AI with automatic retries and logic branching.

Workflow logic with Mastra AI

Create complex sequences where your agent checks `list_mailings` and decides the next step based on performance. If a mailing fails, Mastra AI can trigger a retry logic block automatically. This MCP Server fits right into your existing agent graph. It treats your email data as just another node in your automation chain.

Monitor hooks in Mastra AI

Keep tabs on your infrastructure by calling `list_webhooks`. If you see an unexpected configuration, your agent can flag it for manual review immediately. It removes the need to log into the dashboard constantly. Your agent handles the monitoring and reports back to you when something looks off.

Sync custom fields in Mastra AI

Use `list_fields` to verify your data schema before pushing member updates. It ensures your automation flows don't crash due to missing or renamed fields. Integrating this into your Mastra agent provides a safety net. You validate the structure first, then perform the action.

Setup guide

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

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

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

Common questions about Emma MCP in Mastra AI

You add the server to your agent definition and use the tools within your agent's steps. Mastra AI handles the execution order and state management.

Yes, you can set `requireToolApproval: true` for any Emma tool. This forces a human-in-the-loop check before the agent performs actions like `create_group`.

You can. If you need to iterate through members, the agent can call `list_members` repeatedly until it finds the record you need.

Mastra AI treats your execution environment as a secure sandbox. The member email addresses and names never leave your infrastructure during processing.
