Overview

CheckMX is an MCP server that lets you verify emails and review cold email campaigns, mailboxes, replies and deliverability without leaving your AI assistant. Instead of switching between tools, you call CheckMX directly as an MCP resource, letting Claude, Cursor, VS Code and other clients access email verification and campaign insights on demand.

It runs as a remote service hosted at https://checkmx.dev/mcp with no local installation required. Authentication is not needed, making it straightforward to connect. The latest release is v0.1.0.

CheckMX is listed in the Communication category on mcp.site and works with all MCP-compatible clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf and Zed. If you maintain CheckMX, claim this listing to verify your ownership, earn the Verified badge and keep information up to date.
