Neo4j MCP Server

Fork of the Neo4j Model Context Protocol (MCP) server with environment variable support and improved configuration options.

Features

  • Environment variable configuration for Neo4j connection
  • Support for custom ports and remote Neo4j instances
  • Improved error handling and logging
  • Compatible with the Model Context Protocol

Configuration

The server can be configured using the following environment variables:

  • NEO4J_URL - Neo4j connection URL (default: "bolt://localhost:7687")
  • NEO4J_USER - Neo4j username (default: "neo4j")
  • NEO4J_PASSWORD - Neo4j password (default: "neo4j")

Example:

NEO4J_URL="bolt://192.168.0.157:28687" \ NEO4J_USER="neo4j" \ NEO4J_PASSWORD="your-password" \ node dist/servers/mcp-neo4j-memory/main.js

Available Tools

mcp-neo4j-memory

Knowledge graph memory stored in Neo4j with the following capabilities:

  • create_entities - Create multiple new entities in the knowledge graph
  • create_relations - Create relations between entities (in active voice)
  • add_observations - Add new observations to existing entities
  • delete_entities - Delete entities and their relations
  • delete_observations - Delete specific observations from entities
  • delete_relations - Delete specific relations
  • read_graph - Read the entire knowledge graph
  • search_nodes - Search for nodes based on a query
  • open_nodes - Open specific nodes by their names

Development

# Install dependencies npm install # Build npm run build # Start the server npm start

Changes from Upstream

  • Added environment variable support for Neo4j connection details
  • Improved error handling and connection management
  • Added detailed logging for debugging
  • Updated configuration to support remote Neo4j instances
