project-synapse-mcp vs MCP-Nest

project-synapse-mcp: Project Synapse MCP server creates a persistent, compounding knowledge base by integrating a Neo4j graph database with an Obsidian Markdown wiki. It processes raw text into interconnected graph nodes with vector embeddings, while maintaining a human-readable wiki layer.; 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.
