+CodeContext is a cross-platform C# CLI tool and MCP (Model Context Protocol) server for Mac, Windows, and Linux that turns a codebase into text for an LLM to see its context. It's a code context tool built for prompt engineering: feed a project straight into ChatGPT, Claude, or any other LLM-based coding assistant without manually copy-pasting files.
 
 It scans project directories, generates a structured representation of the project, and extracts relevant file contents while intelligently filtering out unnecessary files and directories. Now with **token budget optimization** and **relevance-based file selection** for agentic coding workflows!
