From the project README

Plainmail for Claude

Real mailboxes on your own domains, set up and handled from Claude. Ask "set up [email protected]" and Claude adds the domain to Plainmail, writes the MX, SPF, DKIM and DMARC records at your DNS host (Cloudflare, Vercel or Porkbun, or gives you the records to copy anywhere else), waits until they're live and creates the mailbox. After that it can read, send and reply to mail on that address. The mailbox is a normal IMAP account, so it also works in Apple Mail, the Gmail app, Outlook or Thunderbird.

What's inside

  • The Plainmail remote MCP server (https://app.plainmail.dev/api/mcp/mcp), signed in with OAuth. No API key to copy.
  • A set-up-email skill with the setup steps.

Install

/plugin marketplace add jdcodes1/plainmail-claude-plugin
/plugin install plainmail@plainmail

Then run /mcp, pick plainmail and sign in. You choose which permissions to allow: read mail, send and organize mail, and manage domains and mailboxes.

You need a Plainmail account ($5 a month for up to 50 domains).

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
