Codeix

Codeix is an open-source MCP (Model Context Protocol) server that delivers fast, semantic code search and navigation features to AI coding agents and assistants like Claude and Cursor. It provides a pre-built, shareable structured index of your codebase, allowing LLM-powered agents to instantly find symbols, references, callers, and other code structures without expensive token usage or manual scanning. Codeix is designed for developers, AI agent builders, and teams working on large or multi-repo codebases, and integrates with major platforms (Git, npm, PyPI, crates.io) to deliver portable, queryable code intelligence.
