# 🧠🕸️ Neo4j Knowledge Graph Memory MCP Server mcp-name: io.github.neo4j-contrib/mcp-neo4j-memory ## 🌟 Overview A Model Context Protocol (MCP) server implementation that provides persistent memory capabilities through Neo4j graph database integration. By storing information in a graph structure, this server maintains complex relationships between entities as memory nodes and enables long-term retention of knowledge that can be queried and analyzed across multiple conversations or sessions. With [Neo4j Aura](https://console.neo4j.io) you can host your own database server for free or share it with your collaborators. Otherwise you can run your own Neo4j server locally. The MCP server leverages Neo4j's graph database capabilities to create an interconnected knowledge base that serves as an external memory system. Through Cypher queries, it allows exploration and retrieval of stored information, relationship analysis between different data points, and generation of insights from the accumulated knowledge. This memory can be further enhanced with Claude's capabilities. ### 🕸️ Graph Schema * `Memory` - A node representing an entity with a name, type, and observations. * `Relationship` - A relationship between two entities with a type. ### 🔍 Usage Example ``` Let's add some memories I, Michael, living in Dresden, Germany work at Neo4j which is headquartered in Sweden with my colleagues Andreas (Cambridge, UK) and Oskar (Gothenburg, Sweden) I work in Product Management, Oskar in Engineering and Andreas in Developer Relations. ``` Results in Claude calling the create_entities and create_relations tools.   ## 📦 Components ### 🔧 Tools The server offers these core tools: #### 🔎 Query Tools - `read_graph` - Read the entire knowledge graph - No input required - Returns: Complete graph with entities and relations - `search_nodes` - Search for nod…
