Microsoft, a corporate parent of Github and Github, joined the MCP Steering Committee, an Anthropic standard for connecting AI models to systems where data resides.

The announcement was presented at the Microsoft Build 2025 conference on Monday, as MCP gained Steam in the AI ​​industry. Earlier this year, both OpenAI and Google said they will support MCP in their respective AI products.

MCP allows models to plot data from sources such as business tools and software to complete tasks, as well as content repositories and application development environments. This protocol enables developers to build bidirectional connections between data sources and AI-powered applications such as chatbots.

Developers can expose data through "MCP Server" and build "MCP clients" (e.g., applications and workflows) to connect to these servers on commands.

Microsoft and Github say they will provide "widespread first-party support" for MCP in their platforms and services, including Microsoft Azure and Windows 11. For example, in the next few months, Windows will get MCP integration, allowing developers to expose the functionality of an application as a model enabled by MCP.

"Developers will be able to wrap the required features and functionality in their applications as MCP servers and make them for Windows (…)." Microsoft explains. "This will include Windows system features such as file systems, windows and Windows subsystems as Linux as the MCP server to which (model) interacts."

Github and Microsoft have also made some contributions to the MCP standard.

Microsoft said its identity and security team worked with humans, the MCP steering committee and the broader MCP community to design an updated authorization specification that allows MCP-connected applications to connect to MCP servers more securely. This specification enables people to use a “trusted login method” that enables AI-powered applications to access data and services, including personal storage drives and subscription plans.

Meanwhile, Github said IT and the MCP Steering Committee worked together to design registry services for MCP servers. This service allows developers to implement public or private centralized repositories for MCP server entries and facilitates and manages related configurations for various MCP implementations.
