SimpleVerifier MCP

A remote Model Context Protocol server that provides email verification, phone format checking, and domain analysis tools for AI agents. It performs live SMTP mailbox checks to determine if an email is valid, risky, or invalid, and verifies phone number formats and domain DNS records like MX, SPF, and DMARC.

Claude Code

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

Claude Code configuration

claude mcp add --transport http simpleverifier-mcp https://simpleverifier.com/api/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 simpleverifier-mcp --url https://simpleverifier.com/api/mcp

Cursor

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

Cursor configuration

{
  "mcpServers": {
    "simpleverifier-mcp": {
      "url": "https://simpleverifier.com/api/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
