<h1>Code Search MCP</h1>
Universal MCP server for intelligent code search across any programming language
<h2>Overview</h2>
Code Search MCP is a high-performance Model Context Protocol server that enables LLMs to intelligently search and analyze codebases across 12 programming languages with comprehensive AST search support for 15 languages. Built on our universal-ctags wrapper, ripgrep, and ast-grep, it provides fast symbol search, structural AST pattern matching, text search, file search, and dependency analysis with persistent caching for 80%+ faster startup times.
