How to Use the eSputnik MCP in Mastra AI

Q: How do I initialize the eSputnik MCP Server in Mastra AI?

Install @mastra/mcp and instantiate a new MCPClient. Pass your Vinkius URL in the servers configuration block. Then call listTools() to expose the operations to your agent.

Q: Does the eSputnik integration with Mastra AI require human approval?

You decide. Setting requireToolApproval to true forces the workflow to pause before sending a blast. A human reviews the payload before the agent proceeds.

Build resilient eSputnik marketing workflows with Mastra AI and handle delivery failures automatically.

Perplexity

Conditional workflow branching

The `trigger_event` tool kicks off complex Mastra AI workflows the second a customer takes action. Your agent catches the signal and decides what happens next based on your conditional logic. Sending messages requires fallback plans. If `send_smart_send` fails to deliver an email due to a temporary outage, Mastra's built-in exponential backoff catches the error and tries again. You don't lose the lead over a network blip.

Dynamic data management

The `get_contact` tool pulls a user's current status before your agent makes any routing decisions. Knowing exactly what segments a person belongs to prevents redundant messaging. Shifting users between lists happens constantly. Your agent can run `detach_from_group` to pull a buyer out of a prospect list, then immediately fire `attach_to_group` to put them in the customer bucket.

Account auditing with this MCP Server

The `get_account_info` tool exposed by this MCP Server gives your Mastra AI agent instant access to organizational metadata. Checking your account standing before running a massive batch operation prevents rate-limit disasters. Pulling bulk data works through `list_contacts`. If your agent needs to audit a specific segment, it grabs the list and processes each record through your custom retry logic.

Setup guide

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

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

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

Common questions about eSputnik MCP in Mastra AI

Install `@mastra/mcp` and instantiate a new `MCPClient`. Pass your Vinkius URL in the servers configuration block. Then call `listTools()` to expose the operations to your agent.

That is exactly what the framework does best. If an API call drops, Mastra catches the error and applies exponential backoff before trying again.

You decide. Setting `requireToolApproval` to true forces the workflow to pause before sending a blast. A human reviews the payload before the agent proceeds.

The client automatically detects the best available connection. It defaults to Streamable HTTP or SSE based on your Vinkius endpoint configuration.

The system routes group membership details and unsubscribed lists through a zero-trust architecture. Your credentials stay locked at the provider level, and the execution environment spins down immediately after the workflow resolves.
