What is the Shipmail MCP server?

Shipmail MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. Official Model Context Protocol (MCP) server for Shipmail, a business email provider with REST API, webhooks, and custom-domain inboxes for AI agents.

What you get

Shipmail uses the stateless MCP 2026-07-28 protocol on both transports. Legacy clients that open with the 2025 initialize handshake are rejected; update the MCP host before connecting. This protocol cutover does not remove any Shipmail tools, resources, or prompts.

What the assistant can call

Once Shipmail is connected, these are the calls the assistant has available:

  • MCPMailmcpmail.app
  • MailRiftmailrift.io
  • MCPEmailsmcpemails.com
  • Group — Tools
  • Status — shipmail_status
  • Domains — shipmail_list_domains, shipmail_get_domain, shipmail_get_domain_dns_records, shipmail_create_domain, shipmail_update_domain, shipmail_delete_domain
  • Mailboxes — shipmail_list_mailboxes, shipmail_get_mailbox, shipmail_create_mailbox, shipmail_update_mailbox, shipmail_delete_mailbox, shipmail_suspend_mailbox
  • Cursor — Add to .cursor/mcp.json in the project root, or ~/.cursor/mcp.json for global use:
  • Windsurf — The Windsurf tool exposed by this server

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

Configuration and credentials

You will need one environment variable: SHIPMAIL_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Choosing this one

Plenty of team communication servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Shipmail's toolset — MCPMail, MailRift, MCPEmails and 6 more — is a fair guide to whether it matches your workflow. It is maintained by GitHub Actions; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Before you rely on it

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 9 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Shipmail.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the shipmail mcp server does with a few real requests.
