Claude Code

Claude Code is Anthropic’s agentic coding tool. Connect it to the MailCraft MCP server and it can send email, manage contacts, build automations and fix a domain’s DNS right from your terminal.

Prerequisites

  • Claude Code installed
  • A MailCraft API key with the scopes you want the agent to have — create one under Settings → API keys.

Setup

  1. 1

    Add the server

    Run this in your terminal. It registers MailCraft for your user; use --scope project to share it with a repository instead.

    terminal
    claude mcp add --transport http mailcraft https://mcp.mailcraft.host \
  --header "Authorization: Bearer sk_live_your_api_key"

    Replace sk_live_your_api_key with your key. The agent only gets the tools that key's scopes allow.

  2. 2

    Verify the connection

    Start Claude Code and run /mcp — mailcraft should be listed as connected. Then ask it something:

    claude
    List all my MailCraft domains

Prefer signing in? Run the same command without --header, then choose mailcraft in /mcp and authenticate in your browser.

Example prompts

Once connected, try asking Claude Code:

  • Send a test email from [email protected] to me and show me its delivery status
  • Which of my domains are still missing DNS records?
  • Create a welcome automation that sends the "Welcome" template, waits three days, then sends "Getting started"
