Model Context Protocol (MCP) server for the Kraiter email platform. Lets Claude and other AI assistants manage contacts, send emails, run sequences, and more — via natural language.

npm install -g @kraiter/mcp-server

The server requires a KRAITER_API_KEY environment variable. Generate one from Settings in the dashboard.

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "kraiter": {
      "command": "npx",
      "args": ["-y", "@kraiter/mcp-server"],
      "env": {
        "KRAITER_API_KEY": "your-api-key-here"
      }
    }
  }
}

claude mcp add kraiter -- npx -y @kraiter/mcp-server

Then set the environment variable in your project's .claude/settings.json:

{
  "env": {
    "KRAITER_API_KEY": "your-api-key-here"
  }
}

Or add the full server config manually:

{
  "mcpServers": {
    "kraiter": {
      "command": "npx",
      "args": ["-y", "@kraiter/mcp-server"],
      "env": {
        "KRAITER_API_KEY": "your-api-key-here"
      }
    }
  }
}

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "kraiter": {
      "command": "npx",
      "args": ["-y", "@kraiter/mcp-server"],
      "env": {
        "KRAITER_API_KEY": "your-api-key-here"
      }
    }
  }
}

Add to .cursor/mcp.json or via Cursor Settings > MCP:

{
  "mcpServers": {
    "kraiter": {
      "command": "npx",
      "args": ["-y", "@kraiter/mcp-server"],
      "env": {
        "KRAITER_API_KEY": "your-api-key-here"
      }
    }
  }
}

Once configured, you can ask Claude things like:

• "Create a contact for alice@example.com with firstName Alice"
• "Send a welcome email to alice@example.com using the welcome-template"
• "List all active campaigns"
• "Show me the timeline for bob@example.com"
