GitHub Copilot for Visual Studio adds MCP server trust layer and C++ support

GitHub released its June 2026 update for Copilot in Visual Studio, adding a trust layer for Model Context Protocol (MCP) servers, improved usage analytics visibility, and the first C++ language scenarios for the AI coding assistant.

MCP server trust controls

The update introduces a new trust layer for MCP servers, allowing developers to control which external context providers Copilot can access. MCP, initially developed by Anthropic, enables AI assistants to connect to external data sources and tools through a standardized protocol. The trust layer addresses security concerns by requiring explicit permission before Copilot connects to third-party MCP servers.

This follows growing adoption of MCP across development tools, with GitHub positioning the trust controls as essential for enterprise environments where code security and data governance are critical.

Enhanced usage visibility

Developers can now view more detailed analytics about their Copilot usage directly within Visual Studio. According to GitHub, this includes metrics on acceptance rates, which suggestions are being used, and how frequently Copilot is invoked across different file types and projects.

The enhanced visibility aims to help individual developers and teams understand their AI assistance patterns and measure productivity impact.

C++ language support begins

The update includes what GitHub describes as "the first C++ scenarios" for Copilot in Visual Studio. While GitHub has not disclosed specific details about which C++ features are supported, this marks the initial phase of expanding Copilot's capabilities beyond its strongest languages like Python, JavaScript, and TypeScript.

C++ developers have historically received less comprehensive AI assistance compared to higher-level languages due to the complexity of C++'s syntax, build systems, and memory management patterns.

Availability

The June 2026 update is available now for Visual Studio users with active GitHub Copilot subscriptions. Pricing remains unchanged at $10 per month for individuals or $19 per month for Copilot Business.

What this means

The MCP trust layer signals GitHub's recognition that enterprise adoption of AI coding assistants requires granular security controls, particularly as these tools connect to increasingly diverse external data sources. The C++ support, though limited in this initial release, addresses a significant gap for systems programmers who have been underserved by AI coding tools. The enhanced usage analytics may help justify Copilot's ROI for organizations evaluating AI coding assistant adoption at scale.
