## Introduction

This guide walks you through connecting Verifiedemail to the OpenAI Agents SDK using the Composio tool router. By the end, you'll have a working Verifiedemail agent that can verify if this email address is valid, check remaining email verification credits, get status of your recent file upload through natural language commands.
This guide will help you understand how to give your OpenAI Agents SDK agent real control over a Verifiedemail account through Composio's Verifiedemail MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## TL;DR

Here's what you'll learn:
- Get and set up your OpenAI and Composio API keys
- Install the necessary dependencies
- Initialize Composio and create a Tool Router session for Verifiedemail
- Configure an AI agent that can use Verifiedemail as a tool
- Run a live chat session where you can ask the agent to perform Verifiedemail operations

## What is OpenAI Agents SDK?

The OpenAI Agents SDK is a lightweight framework for building AI agents that can use tools and maintain conversation state. It provides a simple interface for creating agents with hosted MCP tool support.
Key features include:
- Hosted MCP Tools: Connect to external services through hosted MCP endpoints
- SQLite Sessions: Persist conversation history across interactions
- Simple API: Clean interface with Agent, Runner, and tool configuration
- Streaming Support: Real-time response streaming for interactive applications

## What is the Verifiedemail MCP server, and what's possible with it?

The Verifiedemail MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Verifiedemail account. It provides structured and secure access to your email verification services, so your agent can perform actions like verifying email addresses, cleaning email lists, checking credit balances, and managing credential sharing on your behalf.
- Real-time email verification: Instantly check the validity and deliverability of any email address, ensuring your messages reach real recipients.
- Bulk email list cleaning: Automate the process of uploading and verifying large email lists to maintain high deliverability and reduce bounce rates.
- Credit balance monitoring: Let your agent retrieve and monitor your remaining verification credits so you never run out unexpectedly.
- Credential sharing and management: Fetch and update shared credentials securely, supporting workflows where multiple users need access or updates to verification data.
- File verification status tracking: Poll and check the progress of bulk email verification jobs, helping you stay updated on list cleaning operations.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `VERIFIEDEMAIL_CHECK_CREDITS` | Check Credits | Tool to retrieve the remaining verification credits. Call before VERIFIEDEMAIL_VERIFY_EMAIL operations—especially in bulk or repeated workflows—as VERIFIEDEMAIL_VERIFY_EMAIL fails immediately when credits are exhausted. Use after confirming account authentication to ensure sufficient credits before proceeding. |
| `VERIFIEDEMAIL_CHECK_FILE_STATUS` | Check File Status | Tool to check the status of a previously uploaded file. Use after uploading a file when polling for verification progress. |
| `VERIFIEDEMAIL_GET1_CLICK_USER_DATA` | Get 1-Click User Data | Tool to retrieve data for a user who has completed a 1-Click Signup flow. Use after you have the identityUuid to fetch the verified user's full profile. |
| `VERIFIEDEMAIL_GET_ENTITLEMENTS` | Get Entitlements | Tool to retrieve information about available credits across different entitlement types. Use when you need to check credit availability before performing operations that consume credits. |
| `VERIFIEDEMAIL_GET_SHARED_CREDENTIALS` | Get Shared Credentials | Tool to retrieve a list of shared credential IDs. Use when you need to fetch all credentials shared to your account after authentication. |
| `VERIFIEDEMAIL_LIST_DOWNLOADS` | List Downloads | Tool to get a list of previously created download requests. Use when you need to retrieve information about download requests that have been created for verification results. |
| `VERIFIEDEMAIL_LIST_LISTS` | List Lists | Tool to get all email lists in your account. Use when you need to retrieve and view all verification lists with optional pagination and sorting. |
| `VERIFIEDEMAIL_POST1_CLICK_CREDENTIALS_UPDATE` | Update 1-Click Credentials | Tool to update 1-Click credentials. Use after obtaining a 1-Click session uuid when you need to update user-provided credential values in a non-hosted or trusted flow. |
| `VERIFIEDEMAIL_VERIFY_EMAIL` | Verify Email | Tool to verify the deliverability and validity of an email address. Use when you need to confirm if an email can receive mail by checking server existence, mailbox status, and more. For bulk use, call VERIFIEDEMAIL_CHECK_CREDITS first — this tool fails if verification credits are exhausted. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Verifiedemail MCP server is an implementation of the Model Context Protocol that connects your AI agent to Verifiedemail. It provides structured and secure access so your agent can perform Verifiedemail operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- Composio API Key and OpenAI API Key
- Primary know-how of OpenAI Agents SDK
- A live Verifiedemail project
- Some knowledge of Python or Typescript

### 1. Getting API Keys for OpenAI and Composio

OpenAI API Key
- Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider.
- Keep the API key safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Go to Settings and copy your API key.

### 2. Install dependencies

Install the Composio SDK and the OpenAI Agents SDK.
```python
pip install composio_openai_agents openai-agents python-dotenv
```

```typescript
npm install @composio/openai-agents @openai/agents dotenv
```

### 3. Set up environment variables

Create a .env file and add your OpenAI and Composio API keys.
```bash
OPENAI_API_KEY=sk-...your-api-key
COMPOSIO_API_KEY=your-api-key
USER_ID=composio_user@gmail.com
```

### 4. Import dependencies

What's happening:
- You're importing all necessary libraries.
- The Composio and OpenAIAgentsProvider classes are imported to connect your OpenAI agent to Composio tools like Verifiedemail.
```python
import asyncio
import os
from dotenv import load_dotenv

from composio import Composio
from composio_openai_agents import OpenAIAgentsProvider
from agents import Agent, Runner, HostedMCPTool, SQLiteSession
```

```typescript
import 'dotenv/config';
import { Composio } from '@composio/core';
import { OpenAIAgentsProvider } from '@composio/openai-agents';
import { Agent, hostedMcpTool, run, OpenAIConversationsSession } from '@openai/agents';
import * as readline from 'readline';
```

### 5. Set up the Composio instance

No description provided.
```python
load_dotenv()

api_key = os.getenv("COMPOSIO_API_KEY")
user_id = os.getenv("USER_ID")

if not api_key:
    raise RuntimeError("COMPOSIO_API_KEY is not set. Create a .env file with COMPOSIO_API_KEY=your_key")

# Initialize Composio
composio = Composio(api_key=api_key, provider=OpenAIAgentsProvider())
```

```typescript
dotenv.config();

const composioApiKey = process.env.COMPOSIO_API_KEY;
const userId = process.env.USER_ID;

if (!composioApiKey) {
  throw new Error('COMPOSIO_API_KEY is not set. Create a .env file with COMPOSIO_API_KEY=your_key');
}
if (!userId) {
  throw new Error('USER_ID is not set');
}

// Initialize Composio
const composio = new Composio({
  apiKey: composioApiKey,
  provider: new OpenAIAgentsProvider(),
});
```

### 6. Create a Tool Router session

What is happening:
- You give the Tool Router the user id and the toolkits you want available. Here, it is only verifiedemail.
- The router checks the user's Verifiedemail connection and prepares the MCP endpoint.
- The returned session.mcp.url is the MCP URL that your agent will use to access Verifiedemail.
- This approach keeps things lightweight and lets the agent request Verifiedemail tools only when needed during the conversation.
```python
# Create a Verifiedemail Tool Router session
session = composio.create(
    user_id=user_id,
    toolkits=["verifiedemail"]
)

mcp_url = session.mcp.url
```

```typescript
// Create Tool Router session for Verifiedemail
const session = await composio.create(userId as string, {
  toolkits: ['verifiedemail'],
});
const mcpUrl = session.mcp.url;
```

### 7. Configure the agent

No description provided.
```python
# Configure agent with MCP tool
agent = Agent(
    name="Assistant",
    model="gpt-5",
    instructions=(
        "You are a helpful assistant that can access Verifiedemail. "
        "Help users perform Verifiedemail operations through natural language."
    ),
    tools=[
        HostedMCPTool(
            tool_config={
                "type": "mcp",

                "require_approval": "never",
            }
        )
    ],
)
```

```typescript
// Configure agent with MCP tool
const agent = new Agent({
  name: 'Assistant',
  model: 'gpt-5',
  instructions:
    'You are a helpful assistant that can access Verifiedemail. Help users perform Verifiedemail operations through natural language.',
  tools: [
    hostedMcpTool({
      serverLabel: 'tool_router',
      serverUrl: mcpUrl,
      headers: { 'x-api-key': composioApiKey },
      requireApproval: 'never',
    }),
  ],
});
```

## Conclusion

This was a starter code for integrating Verifiedemail MCP with OpenAI Agents SDK to build a functional AI agent that can interact with Verifiedemail.
Key features:
- Hosted MCP tool integration through Composio's Tool Router
- SQLite session persistence for conversation history
- Simple async chat loop for interactive testing
You can extend this by adding more toolkits, implementing custom business logic, or building a web interface around the agent.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Verifiedemail MCP?

With a standalone Verifiedemail MCP server, the agents and LLMs can only access a fixed set of Verifiedemail tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Verifiedemail and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with OpenAI Agents SDK?

Yes, you can. OpenAI Agents SDK fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Verifiedemail tools.

### Can I manage the permissions and scopes for Verifiedemail while using Tool Router?

Yes, absolutely. You can configure which Verifiedemail scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Verifiedemail data and credentials are handled as safely as possible.
