mcp-neo4j

MCP.Pizza Chef: neo4j-contrib

The mcp-neo4j server is an MCP server integration that connects large language models with Neo4j graph databases. It allows users to interact with Neo4j using natural language commands, which are translated into Cypher queries for execution. This server supports querying database schemas, reading and writing graph data, and managing knowledge graph memory. It integrates with MCP clients like Claude Desktop, VS Code, and others, enabling tasks such as visualizing top products, listing instances, creating new Aura instances, and storing collaborative work facts. The mcp-neo4j server streamlines graph data operations by bridging LLMs and Neo4j, enhancing productivity and data insight through conversational AI.

Neo4j MCP Clients & Servers

Model Context Protocol (MCP) is a standardized protocol for managing context between large language models (LLMs) and external systems.

This lets you use Claude Desktop, or any other MCP Client (VS Code, Cursor, Windsurf), to use natural language to accomplish things with Neo4j and your Aura account, e.g.:

  • What is in this graph?
  • Render a chart from the top products sold by frequency, total and average volume
  • List my instances
  • Create a new instance named mcp-test for Aura Professional with 4GB and Graph Data Science enabled
  • Store the fact that I worked on the Neo4j MCP Servers today with Andreas and Oskar
