Overview

Domain Mail Check is a Model Context Protocol server that inspects how a domain is configured for email and reveals its registrar by querying public DNS records. It exposes domain email setup details as tools your AI assistant can invoke directly, without needing to leave your chat or code editor.

The server runs remotely at https://mailcheck.openkrill.app/mcp, so there's nothing to install locally and no authentication required. Version v1.0.0 is the current release.

Domain Mail Check is listed in the Communication category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this server for openkrill.app, you can claim this listing to verify ownership and keep the information up to date.

▸Hosted endpoint — Streamable HTTP · https://mailcheck.openkrill.app/mcp
