Active·★ 11·MIT·Updated 2026-07-29

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.

Features

01Knowledge Graph (Neo4j 2026.x) with native vector support, hybrid search, Montague Grammar, and a Zettelkasten engine for autonomous insight generation.
02LLM-WIKI Integration bridging Obsidian Markdown vaults with the Neo4j graph, offering full page CRUD, automatic index generation, and health checks.
03Web Content Ingestion via 'defuddle' for cleaning and ingesting web pages, and automated processing of local files into the knowledge base.
04Local-Only Embeddings using sentence-transformers or Ollama, ensuring all vector processing and storage happens without relying on paid APIs.
