📌Overview

Purpose: This framework aims to enhance the code editing experience by providing comprehensive language support and functionality through a Model Context Protocol (MCP) server.

Overview: The language-server-mcp is a TypeScript-based server designed to leverage the Model Context Protocol, facilitating seamless tools for code analysis, completion, and diagnostics. It serves as a model of MCP concepts while targeting primarily TypeScript, with potential for expansion to other languages like Python.

Key Features:

• Language Support: Offers hover information, code completion suggestions, and diagnostic reporting to improve the coding workflow.

• MCP Integration: Implements the MCP protocol for effective communication with clients, exposing various language features as MCP tools.

• Tools: Provides specific functions like get_hover, get_completions, and get_diagnostics that retrieve relevant information based on the language and document position.
