The End of App Switching: How MCP Servers Will Make Traditional UIs Obsolete

Picture this: You're a sales manager who needs to check your pipeline in Salesforce, update a marketing campaign in HubSpot, review code in GitHub, and schedule a meeting in Calendar. This means opening four different browser tabs, remembering four different interfaces, and context-switching between completely different workflows.

What if I told you that soon, you'll do all of this from a single chat window?

The future of software interaction isn't about better buttons or sleeker interfaces. It's about eliminating interfaces altogether. Thanks to a revolutionary technology called Model Context Protocol (MCP), the only UI you'll need is a simple chat box—the same one you're already using in applications like Cursor or Claude.

This isn't just another productivity hack. It's a fundamental shift in how we interact with software, and it's happening right now.

What is MCP? The Protocol That's Changing Everything

Model Context Protocol (MCP) is a standardized way for AI assistants to connect directly with your tools and applications. Think of it as a universal translator that allows your AI to speak fluently with any software you use.

Instead of you learning how to navigate Salesforce's interface, your AI learns how to interact with Salesforce's data and functions. Instead of you clicking through HubSpot's menus, your AI accesses HubSpot's capabilities directly. The AI becomes your interface to every application you use.

But here's the key innovation: MCP doesn't just connect to one tool at a time. It creates what we call "packs of contexts" which are curated collections of tools and data sources that work together seamlessly. Your sales context might include Salesforce, Gmail, Calendar, and your CRM analytics. Your development context might include GitHub, Jira, Docker, and your deployment tools.

You choose which pack of contexts to activate, and suddenly your AI has access to everything you need for that specific workflow. No clicking through 12 buttons on Salesforce to find the correct customer.
