Shipmail MCP Overview

shipmail-mcp connects MCP-compatible agents to Shipmail, a business email platform for custom-domain inboxes and related workflows. It exposes Shipmail API capabilities over a hosted Streamable HTTP endpoint or a local stdio process, using a Shipmail API key for access. Agents can work with domains, mailboxes, messages, threads, webhooks, calendars, bookings, newsletters, and other account features. Reach for it when an agent needs its own business mailbox that can be shared with REST clients, webhooks, IMAP/SMTP clients, or human users.

Primary Use Cases for Shipmail MCP:
  • Create a dedicated custom-domain mailbox for an AI agent
  • Read and reply to business email through MCP
  • Trigger workflows from Shipmail webhooks
  • Manage newsletters, templates, and audiences
