Notifykit

This one gives Claude direct access to your Next.js notification stack. It exposes MCP tools for sending emails, SMS, and push notifications through a unified interface that works with multiple providers. You'd reach for this when you want your AI agent to trigger alerts, send user notifications, or coordinate multi-channel messaging without you manually wiring up Twilio, SendGrid, or whatever else you're using. It's part of the larger sathergate-toolkit collection, which means it follows the same zero-dependency, stdio transport pattern as their other infrastructure packages. Good fit if you're already running Next.js and want Claude to handle notification logic without leaving the conversation.
