project-synapse-mcp vs seekstone

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.; seekstone: Seekstone is an Obsidian Model Context Protocol (MCP) server that provides AI agents like Claude direct read and write access to your Obsidian vault. It operates filesystem-direct, eliminating the need for the Obsidian app or its Local REST API plugin, offering significantly faster search and drastically reduced context window usage compared to other MCP servers.
