Neo4j MCP Server
A Neo4j MCP server implementation for managing graph database operations through the Model Context Protocol.
🔌 Compatible with both Cursor and Claude Desktop!
Quick Start
You can run the server directly using npx:
# Using a single connection string
NEO4J_CONNECTION=neo4j+s://your-instance.databases.neo4j.io,neo4j,your-password npx neo4j-mcpserver
# Or using separate environment variables
NEO4J_URI=neo4j+s://your-instance.databases.neo4j.io NEO4J_USER=neo4j NEO4J_PASSWORD=your-password npx neo4j-mcpserver
Installation
If you prefer to install the package globally:
npm install -g neo4j-mcpserver
Then run it:
NEO4J_CONNECTION=neo4j+s://your-instance.databases.neo4j.io,neo4j,your-password neo4j-mcpserver
Environment Variables
You can provide the Neo4j connection details in two ways:
Using a single connection string:
NEO4J_CONNECTION=<uri>,<user>,<password>Using separate environment variables:
NEO4J_URI=<your-uri> NEO4J_USER=<your-user> NEO4J_PASSWORD=<your-password>
You can also use a .env file in your project root:
NEO4J_URI=neo4j+s://your-instance.databases.neo4j.io
NEO4J_USER=neo4j
NEO4J_PASSWORD=your-password
Configuration ⚙️
Configuring Cursor 🖥️
To set up the Neo4j MCP server in Cursor:
Open Cursor Settings
Navigate to Features > MCP Servers
Click on the "+ Add New MCP Server" button
Fill out the following information:
Name: Enter a nickname for the server (e.g., "neo4j-mcp")
Type: Select "command" as the type
Command: Enter the command to run the server:
env=NEO4J_URI=your-neo4j-uri,NEO4J_USER=your-neo4j-user,NEO4J_PASSWORD=your-neo4j-password npx -y @neobarrientos/neo4j_mcpserverImportant: Replace the credentials with your actual Neo4j database credentials.
Available Tools 🛠️
neo4j-query
Execute Cypher queries against your Neo4j database.
Example usage in Cursor:
MATCH (n) RETURN n LIMIT 5
Troubleshooting 🔧
If you encounter issues:
Verify Neo4j Credentials
Check that your Neo4j URI, username, and password are correct
Ensure your Neo4j database is accessible
Path Issues
Ensure there are no spaces in the installation path
Use forward slashes (/) in paths
Tool Detection Issues
Try restarting Cursor
Verify the server is running (check Cursor's MCP server list)
Check that environment variables are properly set
Development 👩💻
