DomainRef - domain and email security check

Overview

DomainRef is a Model Context Protocol server that checks domain and email security across multiple authentication and encryption standards. It verifies SPF, DKIM, DMARC, TLS, DNSSEC, and BIMI configurations, then provides exact fixes for any gaps found. Rather than switching between tools, AI assistants can call DomainRef directly as a set of integrated tools.

The server runs remotely at https://domainref.dev/mcp, requiring only an API key for authentication. No local installation is needed. Version v1.0.0 is the current release. This is a pay-per-call service operated by domainref.dev.

DomainRef belongs in the Security category on mcp.site and works with any MCP client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim the listing to verify ownership and keep information up to date.
