Vibe Coding Notifications: How to Use Courier with Cursor or Claude Code

Courier's MCP server lets AI coding tools like Cursor and Claude Code interact directly with your notification infrastructure. Unlike Knock and Novu's MCP servers that focus on API operations, Courier's includes embedded installation guides for Node, Python, Flutter, React, and other platforms. When you prompt "add Courier to my app," your AI assistant pulls accurate setup instructions rather than relying on outdated training data. OneSignal's MCP is community-maintained, not official. Courier supports 50+ providers, native Slack/Teams integration, drop-in inbox and preference components, and a free tier of 10,000 notifications/month. Configure in Cursor with "url": "https://mcp.courier.com" and "headers": { "api_key": "YOUR_KEY" }.

The Complete Guide to B2B Customer Engagement

Courier provides the notification infrastructure layer for B2B customer engagement, routing messages across email, SMS, push, in-app, Slack, and Teams based on user preferences and product events. Unlike building notification systems in-house—which takes months of engineering time for features like multi-channel routing, preference management, and delivery tracking—Courier handles this infrastructure so product teams can focus on engagement strategy. B2B customer engagement requires multiple layers: notification infrastructure (Courier), customer data platforms (Segment), product analytics (Mixpanel/Amplitude), and channel-specific tools. Companies with strong engagement programs see 15-25% churn reduction. The key is connecting product events to customer communication at the right moment through the right channel, handling complexity like multiple users per account with different notification needs across work channels.

Customer Engagement Platform vs CRM: Key Differences Explained

A CRM stores customer data: contacts, purchases, support tickets, and pipeline. It answers "who are our customers?" A customer engagement platform (CEP) orchestrates communication across email, push, SMS, in-app, and chat. It answers "what should we tell them next?" CRMs focus on historical records. CEPs process real-time behavior and trigger messages based on actions. Most teams need both, plus a third layer: notification infrastructure for reliable multi-channel delivery. Courier bridges CEP and infrastructure by combining routing, failover, and delivery tracking with engagement features like preference management, visual templates, and in-app notification centers.
