MailX Email Deliverability is a Model Context Protocol (MCP) server: Check SPF/DKIM/DMARC/BIMI, blacklists, SMTP/IMAP; DNS lookups; generate email DNS records. In practice that means any MCP-compatible AI assistant can call MailX Email Deliverability's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://themailx.com/mcp and you're connected, with nothing to install locally. The current release is v1.0.0.
MailX Email Deliverability is listed under Communication on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
