langgraph-dev-navigator vs MCP-Nest

langgraph-dev-navigator: LangGraph-Dev-Navigator is a framework that grounds AI coding assistants in the executable truth of a specific, version-controlled codebase, reducing hallucinations and improving code reliability. It uses a local git submodule of the official LangGraph repository as ground truth, combined with a knowledge server providing Retrieval-Augmented Generation (RAG) and Knowledge Graph validation. The goal is to create a development environment where AI-generated code is more reliable and aligned with project-specific best practices.; MCP-Nest: This NestJS module simplifies exposing AI tools, resources, and prompts using the Model Context Protocol (MCP). It integrates seamlessly with NestJS's dependency injection to build complex, enterprise-ready MCP servers.
