MailboxValidator

Verified · yesterday

Email validation MCP server using the MailboxValidator API. It can validate email addresses.

Install

claude mcp add mcp-mailboxvalidator -- npx -y [email protected]

Requires: MAILBOXVALIDATOR_API_KEY

Our take

Straightforward MailboxValidator wrapper with three tools for full email validation, disposable-domain checks, and free-email checks. It is thin but honest: you bring a MailboxValidator API key and get the vendor's JSON back in readable MCP responses. The free allowance is small, so production use likely means a paid API plan.
