The rise of Model Context Protocol (MCP) is changing how developers interact with code. This post shares a hands-on session using GitNexus, an MCP server, to understand an entire project. We walk through the setup, the types of queries you can make, and how it accelerates onboarding to unfamiliar codebases. The tool allows you to ask questions about project structure, dependencies, and even specific functions, returning context-aware answers. However, we also note limitations, such as the need for a well-indexed repository and occasional inaccuracies in complex codebases. For developers working with large monorepos or legacy code, this approach offers a promising way to reduce cognitive load. We conclude with tips on integrating MCP tools into your daily workflow and what to watch out for.
