You can validate email addresses for outbound campaigns in a lightweight MCP server. It exposes a simple tool that checks an email and returns a straightforward JSON response indicating whether the address exists, making it easy to filter invalid leads before you send messages.

How to use

Use an MCP client to connect to the Email Checker MCP Server and invoke the validate_email tool. Pass the email address you want to validate as a string. The tool returns a small JSON payload that tells you whether the email exists.

How to install

# Prerequisites
- Python 3.x

# Step 1: Clone the project
git clone https://github.com/ravinahp/email-checker-mcp.git

Additional sections

Configuration for running as an MCP server is provided as a stdio-based entry. This uses the uv tool to run the local MCP server binary inside your installation directory. Use this exact configuration in your MCP client setup.

{
  "email-checker-mcp": {
    "command": "uv",
    "args": [
      "--directory",
      "/Users/YOUR_USERNAME/Code/email-checker-mcp",
      "run",
      "email-checker-mcp"
    ]
  }
}

Usage example

Example usage from an MCP client: you pass the email to validate and receive a response that indicates existence.

{
  "exist": true
}
