Show HN: Code Index MCP – Codebase Indexing Server for LLMs

Code Index MCP is an MCP server that indexes codebases and provides search capabilities to LLMs. Supports 50+ file types with automatic indexing, regex/fuzzy search, code analysis, and real-time file monitoring.

LLMs can search your entire project, find files with glob patterns, analyze code structure (functions, classes, imports), and get automatic updates when files change. Eliminates the need to manually copy files or explain project structure to overcome context limits.

Built with Python using the Model Context Protocol. Uses pluggable search backends (ugrep/ripgrep/ag/grep).
