Lsp Mcp
Bridges Claude to Language Server Protocol implementations across 13 languages with zero configuration. Point it at a project root and it detects Python, TypeScript, Rust, Go, or whatever else you're using, then spins up the right language servers automatically. Exposes the full LSP toolkit through MCP tools: jump to definition, find references, pull diagnostics, rename symbols, format code, trigger code actions. Runs locally alongside your code (critical for SSH remotes, WSL, containers), persists workspace state across restarts, and handles polyglot repos by running multiple language servers simultaneously. The lsp_init tool appears only when needed and hides itself after successful setup, though most modern clients skip it entirely via MCP Roots auto-detection.

Universal LSP MCP Server
One MCP server to rule all Language Servers — automatic language detection, zero-config setup.
Overview
A Model Context Protocol (MCP) server that gives language models access to Language Server Protocol (LSP) functionality across all major programming languages. Unlike existing LSP-MCP servers, this project supports 13 languages out of the box with zero manual configuration — it automatically detects your codebase, selects the right language server, and exposes all LSP operations through a stable, language-independent tool interface.
