MCP-Nest vs flexible-graphrag

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.; flexible-graphrag: Flexible GraphRAG is an open-source platform that integrates document processing, automated knowledge graph construction, and hybrid search (full-text, vector, graph) with AI query and chat capabilities. It supports 13 data sources, multiple vector and graph databases, and offers automatic incremental updates to keep data synchronized in real-time.
