Building notifications into your app just got dramatically easier. Courier's new MCP server brings AI-powered notification assistance directly to your IDE, so you can integrate, test, and manage notifications without ever leaving your workspace.
Ready to see the difference? In the video below, we'll walk through setting up Courier MCP in Cursor and show you how to build a complete notification system in minutes, all through natural conversation with your AI assistant.
Available now for Cursor, Claude Code, VS Code, Windsurf, OpenAI API, and more.
Visit our documentation to get started, or talk with a solutions engineer if you're new to Courier.
If you've been using AI coding tools like Cursor or Claude, you know how they've transformed development, but AI agents can hallucinate API details or provide outdated snippets. Model Context Protocol (MCP) servers solve this by giving AI agents deterministic, precise functionality instead of guessing.
Courier MCP connects your AI assistant directly to Courier's platform, eliminating the bounce between documentation, Postman, and your IDE. When you connect Courier MCP to your workspace, you get two powerful capabilities:
Smart Installation Guidance: Your AI assistant knows exactly how to install Courier SDKs, integrate components like Courier Inbox, and implement the latest patterns with accurate, up-to-date code.
Direct Platform Interaction: Send messages, manage users, create lists, and test notifications using natural language—all powered by Courier's reliable infrastructure.
Courier MCP includes everything developers need for daily notification work while keeping you protected. Use your workspace API key to send messages to users and lists, manage user profiles and subscriptions, create notification templates, test push tokens, and generate authentication JWTs.
We've intentionally excluded destructive operations like deletes and limited administrative updates. You can be productive while staying safe, though remember: if you tell the agent to send thousands of emails, it will try—just like any code you'd write yourself.

The $5.9 Billion Rebuild: Why Healthcare Is Replacing Its Notification Infrastructure
The clinical alert and notification market will reach $5.9 billion by 2032, growing at 12.3% annually. That number represents hardware, software, and services combined. It also represents healthcare's admission that pagers and overhead speakers aren't enough anymore. Healthcare organizations are rebuilding how critical information moves through their systems. Regulatory pressure, workforce shortages, and value-based care economics are forcing the investment. The software layer is where outcomes are won or lost.

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.
