MCP Neo4j Server

An MCP server that integrates Neo4j graph database with Claude Desktop, enabling natural language interaction for graph database operations. It allows users to interact with Neo4j using natural language through Claude Desktop.

Quick Start

Run the server directly using npx @alanse/mcp-neo4j or integrate it into your Claude Desktop configuration by specifying the command, arguments, and environment variables for Neo4j connection details (URI, username, password).

Features

• execute_query: Executes Cypher queries, supporting all types (READ, CREATE, UPDATE, DELETE) with structured results and parameterization.
• create_node: Creates new nodes with labels and properties, supporting all Neo4j data types.
• create_relationship: Creates relationships between nodes, defining type, direction, and properties, requiring source and target node IDs.

Installation

Install via Smithery using npx -y @smithery/cli install @alanse/mcp-neo4j-server --client claude or clone the repository, install dependencies with npm install, and build with npm run build.

Configuration

Requires environment variables: NEO4J_URI, NEO4J_USERNAME, and NEO4J_PASSWORD.

Usage Examples
