kglite vs MCP-Nest

kglite: KGLite is an embedded, Cypher-queryable knowledge graph engine for Python and Rust, designed to serve applications, analysts, and LLM agents without an external database. It offers advanced features like schema-aware descriptions for LLMs, temporal querying over historical data, and a declared ontology for data quality.; 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.
