Neo4j Graph Database MCP Server

Neo4j Graph Database MCP

The Neo4j MCP integration allows you to interact with Neo4j graph databases directly from your AI assistant. This MCP provides three specialized servers that handle different aspects of Neo4j functionality:

Available Servers

1. Neo4j Cypher Server: Translates natural language into Cypher queries and executes them against your Neo4j database
2. Neo4j Memory Server: Creates and maintains a personal knowledge graph in Neo4j that persists across conversations
3. Neo4j Cloud Aura API Server: Manages your Neo4j Aura cloud instances directly from the chat interface

Installation

To use the Neo4j MCP servers, you'll need to:

1. Clone the repository:

   git clone https://github.com/neo4j-contrib/mcp-neo4j.git
   cd mcp-neo4j
   

2. Install the server you want to use. Each server has its own installation instructions in its respective directory.

3. Configure your MCP client (Claude Desktop, VS Code, Cursor, etc.) to use the server by adding the appropriate configuration to your client's settings.

Neo4j Cypher Server

The Cypher server allows you to:

• Get database schema information
• Execute read and write Cypher queries generated from natural language
• Visualize query results

To use it, you'll need to provide connection details for your Neo4j database.

Neo4j Memory Server

The Memory server enables:

• Storing entities and relationships in a personal knowledge graph
• Retrieving information across different sessions and conversations
• Building a persistent memory of facts and connections

This server requires a Neo4j instance (local or remote) to store the knowledge graph.

Neo4j Cloud Aura API Server

The Aura API server lets you:

• List your Aura instances
• Create new instances with specific configurations
• Find instances by name
• Scale instances up or down
• Enable or disable features
• Delete instances

You'll need to provide your Neo4j Aura API credentials to use this server.

Usage Examples

Here are some examples of what you can ask the Neo4j MCP:

• "What is the schema of my database?"
• "Find all products purchased by customers in California"
• "Store the fact that I worked on Project X with John and Sarah yesterday"
• "What do you remember about my work projects?"
• "List all my Aura instances"
• "Create a new Aura Professional instance named 'project-graph' with 4GB memory"

For detailed usage instructions for each server, refer to the README files in the respective server directories within the repository.
