The MCP Language Server is designed to enhance code navigation and analysis by integrating language server protocols for various programming languages into MCP-enabled systems. It provides features like semantic analysis and diagnostics to improve the workflow of developers using LLMs.

MCP Language Server

This project is an MCP server that runs and exposes a language server to LLMs (Large Language Models), enhancing the navigation and analysis of codebases. It provides semantic tools such as get definition, references, rename, diagnostics, and more. Features include support for different languages through their respective servers like gopls for Go, rust-analyzer for Rust, pyright for Python, etc.

Demo

MCP Language Server aids MCP-enabled clients in navigating codebases effectively with tools such as semantic analysis, diagnostic reports, and more.
