Test Mailbox

Test Mailbox is an MCP server that provides disposable email inboxes for automated testing in development and QA workflows. It exposes endpoints and tools via both a REST API and the MCP protocol, allowing AI assistants or automated systems to create inboxes, receive test emails, extract verification links, and clean up—all programmatically. Integrators can use it for testing email sending, verification flows, and related automations without using real email addresses.
