Email List Validation MCP

This MCP server enables AI agents to verify email addresses by checking syntax, MX records, SMTP mailbox status, and disposable email indicators. It supports single and batch verification, provides verdicts such as valid, invalid, risky, or unknown, and allows agents to register for API keys and manage credits directly through MCP tools.

Claude Code

Run this once in a terminal. It registers a Streamable HTTP server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http email-list-validation-mcp https://app.emaillistvalidation.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add email-list-validation-mcp --url https://app.emaillistvalidation.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable email-list-validation-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "email-list-validation-mcp": {
      "url": "https://app.emaillistvalidation.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure). The type must be streamableHttp for a remote HTTP server.

Cline configuration

{
  "mcpServers": {
    "email-list-validation-mcp": {
      "type": "streamableHttp",
      "url": "https://app.emaillistvalidation.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start email-list-validation-mcp and inspect its tools.

{
  "servers": {
    "email-list-validation-mcp": {
      "type": "http",
      "url": "https://app.emaillistvalidation.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http email-list-validation-mcp https://app.emaillistvalidation.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Claude Desktop configuration

    "email-list-validation-mcp": {
      "url": "https://app.emaillistvalidation.com/mcp"
    }
  }
}

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "email-list-validation-mcp": {
      "serverUrl": "https://app.emaillistvalidation.com/mcp"
