Email Verifier is a Model Context Protocol (MCP) server: Verify email deliverability & find business emails (single or bulk) via the Verifox API. Because it speaks the Model Context Protocol, AI assistants can use Email Verifier as a set of callable tools instead of you copy-pasting between apps.
You can run Email Verifier two ways: connect to the hosted endpoint at https://mcp.verifox.ai/mcp with no local install, or run it on your own machine via the npm package verifox-mcp. Configuration happens through environment variables — you'll need VERIFOX_API_KEY. The current release is v1.2.1, with source at verifoxturnix1/verifox-mcp on GitHub.
On mcp.site, Email Verifier sits in the Communication category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
