The momentum of Build 2025 continues, with Microsoft unveiling yet another major advancement—this time focused on deepening the role of artificial intelligence in Windows 11.
The company has announced the integration of a new open standard called the Model Context Protocol (MCP), which is set to reshape how AI models interact with applications and system-level data.
What Is the Model Context Protocol?
At its core, the Model Context Protocol is a framework designed to give AI models access to relevant information beyond the boundaries of a single app. This enables smarter, more context-aware interactions. Instead of relying solely on data from one source, AI agents can draw from a broader ecosystem, improving accuracy, relevance, and usefulness.
To support this, Microsoft has introduced two key components:
- MCP Registry: A secure directory that helps AI agents locate and connect to MCP-enabled servers on a user’s device.
- MCP Servers: These servers grant controlled access to essential system functions—such as the file system, window management, and even the Windows Subsystem for Linux—allowing AI models to work more seamlessly with the OS and user data.
Why It Matters
The introduction of MCP brings several advantages to developers and end users:
- Enhanced Interoperability: AI agents can now collaborate across applications, creating a more unified and intelligent user experience.
- Stronger Security Framework: MCP is built with privacy in mind, ensuring user data is protected while still enabling smarter features.
- Simplified Development: Developers can more easily integrate advanced AI functionality into their apps without reinventing core capabilities.
Industry Adoption Already Underway
Microsoft is already partnering with companies like Figma, Anthropic, and Perplexity to explore MCP’s potential in real-world applications. Interestingly, there was no mention of OpenAI during the announcement, which raises some questions about the dynamics of Microsoft’s broader AI partnerships.
As Microsoft continues to expand the MCP’s reach and capabilities, its long-term impact on Windows 11 and app development could be significant. For now, all eyes are on how this protocol will be implemented and whether it delivers on its promise of smarter, more integrated AI experiences.
