Domain Health

Overview

Domain Health is an MCP server that audits domain configuration and security posture by checking SPF, DKIM, DMARC, BIMI, MTA-STS, SSL/TLS and HTTP security headers. It gives you programmatic access to these critical email and web security checks through the Model Context Protocol, so AI assistants can run audits directly without manual steps.

Domain Health is hosted remotely at https://mcp.modernmustardseed.com/domain-health and requires no local installation or authentication. Version 1.0.0 is the current release. Full documentation is available at https://mcp.modernmustardseed.com/docs/domain-health.

Domain Health is listed 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.
