{
  "mcpServers": {
    "getmailer": {
      "command": "npx",
      "args": ["getmailer-mcp"]
    }
  }
}

2. Ask Claude to sign you up:

"Sign me up for GetMailer with email [email protected] and password MyPassword123"

3. Claude will return your API key. Update your config:

{
  "mcpServers": {
    "getmailer": {
      "command": "npx",
      "args": ["getmailer-mcp"],
      "env": {

      }
    }
  }
}

4. Restart Claude Desktop and start sending emails!
