ezverify-mcp: requires an EzVerify Starter or Business plan

Requires an EzVerify Starter or Business plan. The Free plan is web-app only: its API key is rejected with 403 plan_upgrade_required.

EzVerify MCP server: lets an MCP client such as Claude verify email addresses, run bulk verification jobs and check your credit balance through your EzVerify account.

What is EzVerify MCP Server?

EzVerify MCP Server is a Model Context Protocol (MCP) server that connects Claude and other MCP clients to the EzVerify email verification API. It lets the assistant verify email addresses, submit bulk verification jobs and read your account information on your behalf, from a plain-language conversation.

It calls the EzVerify REST API with your API key, so it needs an EzVerify account on the Starter or Business plan.

Setup

Requires a Starter or Business plan and Node.js 18+. Generate an API key on the API Usage page of your EzVerify dashboard (Dashboard → API Usage). It is shown once, so store it safely; regenerate it if you lose it.

Claude Desktop

Add to claude_desktop_config.json:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "ezverify": {
      "command": "npx",
      "args": ["-y", "ezverify-mcp"],
      "env": {
        "EZVERIFY_API_KEY": "YOUR_EZVERIFY_API_KEY"
      }
    }
  }
}

Restart Claude Desktop after saving.

Claude Code

Add a .mcp.json file at your project root:

{
  "mcpServers": {
    "ezverify": {
      "command": "npx",
      "args": ["-y", "ezverify-mcp"],
      "env": {
        "EZVERIFY_API_KEY": "YOUR_EZVERIFY_API_KEY"
      }
    }
  }
}

Your key is in that file, so do not commit it to source control.

Other MCP clients

Any client that can start a stdio MCP server works the same way: run npx -y ezverify-mcp with the EZVERIFY_API_KEY environment variable set.

How to Use

Once configured, ask your assistant to verify emails in plain English. For example:

• "Verify this email address for me"
• "Check which of these 20 emails are valid"
• "How many credits do I have left?"

Key Features

• Verify a single email address and get a full result including status, deliverability score and detailed flags
• Submit bulk email lists for async verification and poll for results when complete
• Results include disposable-domain, role-account and typo-suggestion flags
• Check your credit usage and remaining balance without logging into the dashboard
• Retrieve your current plan and account information on demand
• Your API key stays in your local configuration and is sent only to ezverify.app; the server does not store or log it
