GitHub Copilot CLI adds Microsoft C++ Language Server plugin with automated setup

GitHub has added the Microsoft C++ Language Server as a plugin to the Copilot Plugins marketplace. The plugin includes a built-in setup skill that automates C++ project configuration.

The integration allows developers to use Copilot CLI to configure C++ language server settings without manual setup. According to GitHub, the new skill helps automate project setup tasks.

What's included

The plugin provides:

• Microsoft C++ Language Server integration through the Copilot Plugins marketplace
• Built-in setup skill for automated project configuration
• CLI-based access to language server capabilities

The plugin is available now through the Copilot Plugins marketplace. GitHub did not disclose pricing details or whether the plugin requires a specific Copilot subscription tier.

Technical context

Language servers implement the Language Server Protocol (LSP), which standardizes communication between development tools and language-specific features like autocomplete, go-to-definition, and error checking. The Microsoft C++ Language Server (also known as clangd or the MSVC language server) provides these capabilities for C++ codebases.

Integrating the language server into Copilot CLI means developers can configure and manage C++ project settings through natural language commands rather than editing configuration files manually.

What this means

This update expands Copilot CLI's language support and reduces friction in C++ development workflows. The automation of language server setup addresses a common pain point: configuring LSP settings across different projects and build systems. For teams working with C++ codebases, this could reduce onboarding time and standardize development environment configuration. The move also signals GitHub's continued investment in making Copilot CLI a general-purpose developer tool beyond code generation.
