How to Use the eSputnik MCP in OpenAI Agents SDK

Q: How do I initialize the eSputnik MCP server in the OpenAI Agents SDK?

Install via pip install openai-agents and create an MCPServerStreamableHttp instance with your endpoint. Pass this in the mcpservers list when initializing your Agent to expose tools like sendsmartsend instantly.

Q: Can my OpenAI Agents SDK system handle contact segmentation in eSputnik automatically?

Yes, your agent uses listgroups to find existing segments and attachtogroup to sort users. The SDK lets you set guardrails so the agent never adds a contact to the wrong list.

Q: How does OpenAI Agents SDK trace eSputnik MCP Server errors?

Every call to tools like getmessagestatus or triggerevent goes through the OpenAI dashboard. If an API key expires or a request fails, you can inspect the full JSON payload in the trace log.

Q: What is the best way to send transactional SMS and email simultaneously?

Use the sendsmartsend tool. Your agent passes the contact details and content, and eSputnik handles the delivery across channels based on your predefined rules.

Q: How does this MCP server protect sensitive contact emails and phone numbers?

All contact data processed by getcontact or createcontact runs in an isolated, ephemeral sandbox. Vinkius handles the authentication headers directly, meaning your raw API keys never leak to the client or LLM logs.

Automated campaign triggering

The `trigger_event` tool fires system events to start multi-step marketing workflows in eSputnik. Your OpenAI Agents SDK setup catches user actions on your platform, decides which event to trigger, and executes it instantly. No manual scripting is required on your end. The SDK handles agent handoffs so a specialized triage agent can hand off to a marketing agent, which then inspects the delivery pipeline with `get_message_status` to ensure your customers get timely updates.

Smart contact management via OpenAI Agents SDK

The `create_contact` tool registers new subscribers directly into your mailing lists. Your agent uses this alongside `attach_to_group` to organize users based on their chat history or purchase intent. By setting `cacheToolsList=True` in your OpenAI Agents SDK configuration, the agent resolves group IDs instantly. It matches users to segments using `list_groups` without hitting rate limits during high-traffic signup spikes.

Target cleanup and suppression

The `list_unsubscribed` tool pulls inactive or opted-out email addresses to clean your mailing lists. Your agent cross-references this list using `detach_from_group` to keep your CRM scrubbed and compliant. OpenAI dashboard tracing lets you watch how the MCP Server handles these sensitive operations. You see every step as the agent queries `search_contacts` and removes opted-out users before the next blast.

Setup guide

Set up eSputnik MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all eSputnik tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives eSputnik tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate eSputnik tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="eSputnik Agent",
            instructions="You have access to eSputnik tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())
