How to integrate Emailvalidation MCP with Atomic Agent

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Emailvalidation.

This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Emailvalidation account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Emailvalidation

Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.

Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

Connect Emailvalidation to Atomic Agent

1. Sign up or sign in to the Composio dashboard. Copy your API key.
2. In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
3. Ask Atomic Agent to do something in Emailvalidation. It searches Composio for the right tool.
4. On first use, open the sign-in link returned in the chat. Connect your Emailvalidation account, then return to Atomic Agent to continue.

Headless setup

Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

The Emailvalidation MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Emailvalidation account. It provides structured and secure access to email deliverability checks and account quota details, so your agent can validate addresses, assess mailbox and domain signals, identify risky addresses, and monitor credit usage on your behalf.

• Email deliverability checks: Have your agent validate an email address and determine whether it is likely to receive messages.
• Format, mailbox, and domain review: Let the agent inspect an address for valid formatting, mailbox status, and domain quality signals.
• Risky address detection: Direct your agent to identify role-based or disposable email addresses before you add them to a contact list.
• Email quality assessment: Instruct your agent to review the available quality signals for an individual address and flag possible concerns.
• Quota and credit monitoring: Have your agent check monthly and grace credit totals, usage, and remaining balances for your account.

Use Emailvalidation from Atomic Agent

With your account connected, ask Atomic Agent to work with Emailvalidation in natural language. You can connect more apps through the same Composio integration as you need them.
