Language Server tools for Copilot

A Visual Studio Code extension that exposes any Language Server Protocol (LSP) capabilities as Model Context Protocol (MCP) tools and GitHub Copilot Language Model Tools. This universal extension works with any programming language that has an active language server in VSCode.

I created this because I work on an incredibly large C++ project (with clangd) and Copilot is not able find objects efficiently.

✨ Demo

Here’s a quick example of how the extension enhances GitHub Copilot’s understanding of a C++ codebase.

🎯 Purpose

This extension bridges the gap between any existing language server’s capabilities and MCP clients + GitHub Copilot, enabling AI models and tools to:

• Navigate codebases intelligently across any programming language
• Provide context-aware code suggestions and analysis
• Answer questions about code structure and functionality
• Assist with code refactoring and analysis
• Automatically enhance GitHub Copilot with deep language server insights
