langgraph-dev-navigator vs Contextcore

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.; Contextcore: ContextCore is a local-first MCP server that indexes your local files (text, code, images, audio, video) and provides hybrid search (BM25 + embeddings) via a single MCP server. It reduces token usage by 57% compared to pasting entire files. It works with Claude Desktop, Claude Code, Cursor, Cline, and any MCP-compatible tool.
