# Package Search

> Use this tool when you need to access versioned source code from major open-source projects, such as Go, Python, and Rust, to analyze language evolution, find reference implementations, or retrieve canonical code examples. It solves problems related to sourcing reliable code examples, tracking changes in software projects, and researching programming language implementations. The tool takes in configurable patterns and GitHub release tags as input and outputs a curated dataset of indexed source code and documentation.

## Description

This MCP server provides access to versioned source code from major open-source projects including Go, Python CPython, Rust, LLVM, Abseil, and Chroma through GitHub releases integration. The implementation automatically tracks and indexes specific file types (source code, documentation) from tagged releases using configurable patterns, maintaining a curated dataset of programming language implementations and core libraries with version sampling to manage dataset size. Designed for developers, researchers, and AI systems that need access to canonical source code examples, language evolution analysis, or reference implementations from foundational software projects across multiple programming ecosystems.
