Validate Email Domains

The `check_disposable` tool runs the full email address against a curated database of temporary providers. This check prevents your agent from generating leads using throwaway domains, which keeps your sender reputation clean. It’s critical for any production system that needs high deliverability.

Guardrails Against Spam

When you pass the email address to `check_disposable`, it immediately returns whether the domain is legitimate or disposable. Your agent's built-in guardrails use this data point, blocking invalid emails *before* they hit your downstream services. This stops fake addresses from corrupting your lead lists.

Advanced Lead Qualification

Use the `check_disposable` tool to qualify incoming contacts right in the agent workflow. If an email fails the disposable check, your agent knows it’s low-quality and can reroute the lead or flag it for manual review. You don't waste time on junk data.

Setup guide

Set up Disposable Email Blocker 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 Disposable Email Blocker tools at runtime.
3

Create your Agent

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

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Disposable Email Blocker 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="Disposable Email Blocker Agent",
            instructions="You have access to Disposable Email Blocker tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())
