e2a MCP

An open-source email API and hosted MCP server that provides AI agents with dedicated two-way inboxes. It enables agents to send transactional emails, receive inbound messages with structured SPF/DKIM/DMARC verification, reply in-thread, and utilize human-in-the-loop approval gates for outbound messages. It supports OAuth authentication without API keys for interactive clients.
