Neo4j Aura Database Manager

STDIO

MCP server for managing Neo4j Aura database instances through Neo4j Aura API integration

🚀💖☁️ Neo4j Aura Database Manager MCP Server

🌟 Overview

A Model Context Protocol (MCP) server implementation that provides tools for managing Neo4j Aura database instances through the Neo4j Aura API.

This server allows you to create, monitor, and manage Neo4j Aura instances directly through Claude, making it easy to provision and maintain your graph database infrastructure.

🔑 Authentication

Authentication with the Neo4j Aura API requires:

  • Client ID
  • Client Secret

You can obtain these credentials from the Neo4j Aura console, see the documentation of the Aura API

Here is the API Specification

🔧 Usage with Claude Desktop

💾 Installation

pip install mcp-neo4j-aura-manager

⚙️ Configuration

Add the server to your claude_desktop_config.json:

"mcpServers": {
  "neo4j-aura": {
    "command": "uvx",
    "args": [
      "[email protected]",
      "--client-id",
      "<your-client-id>",
      "--client-secret",
      "<your-client-secret>"
      ]
  }
}

Alternatively, you can set environment variables:

"mcpServers": {
  "neo4j-aura": {
    "command": "uvx",
    "args": [ "[email protected]" ],
    "env": {
      "NEO4J_AURA_CLIENT_ID": "<your-client-id>",
      "NEO4J_AURA_CLIENT_SECRET": "<your-client-secret>"
    }
  }
}

🐳 Using with Docker

"mcpServers": {
  "neo4j-aura": {
    "command": "docker",
    "args": [
      "run",
      "--rm",
      "-e", "NEO4J_AURA_CLIENT_ID=${NEO4J_AURA_CLIENT_ID}",
      "-e", "NEO4J_AURA_CLIENT_SECRET=${NEO4J_AURA_CLIENT_SECRET}",
      "mcp-neo4j-aura-manager:0.4.3"
    ]
  }
}

🏷️ Namespacing for Multi-tenant Deployments

The server supports namespacing to prefix tool names for multi-tenant deployments:

"mcpServers": {
  "neo4j-aura-app1": {
    "command": "uvx",
    "args": [
      "[email protected]",
      "--client-id", "<your-client-id>",
      "--client-secret", "<your-client-secret>",
      "--namespace", "app1"
    ]
  },
  "neo4j-aura-app2": {
    "command": "uvx", 
    "args": [
      "[email protected]",
      "--client-id", "<your-client-id>",
      "--client-secret", "<your-client-secret>",
      "--namespace", "app2"
    ]
  }
}

CLI Usage

# With namespace
mcp-neo4j-aura-manager --client-id <id> --client-secret <secret> --namespace myapp

# Tools become: myapp-list_instances, myapp-create_instance, etc.

Environment Variables

export NEO4J_AURA_CLIENT_ID=your_client_id
export NEO4J_AURA_CLIENT_SECRET=your_client_secret  
export NEO4J_NAMESPACE=myapp
mcp-neo4j-aura-manager

Docker with Namespacing

docker run -e NEO4J_AURA_CLIENT_ID=<id> \
           -e NEO4J_AURA_CLIENT_SECRET=<secret> \
           -e NEO4J_NAMESPACE=myapp \
           mcp-neo4j-aura-manager

🌐 HTTP Transport Mode

The server supports HTTP transport for web-based deployments and microservices:

# Basic HTTP mode (defaults: host=127.0.0.1, port=8000, path=/mcp/)
mcp-neo4j-aura-manager --transport http

# Custom HTTP configuration
mcp-neo4j-aura-manager --transport http --host 127.0.0.1 --port 8080 --path /api/mcp/

Environment variables for HTTP configuration:

export NEO4J_TRANSPORT=http
export NEO4J_MCP_SERVER_HOST=127.0.0.1
export NEO4J_MCP_SERVER_PORT=8080
export NEO4J_MCP_SERVER_PATH=/api/mcp/
export NEO4J_MCP_SERVER_ALLOWED_HOSTS="localhost,127.0.0.1"
export NEO4J_MCP_SERVER_ALLOW_ORIGINS="http://localhost:3000"
export NEO4J_NAMESPACE=myapp
mcp-neo4j-aura-manager

🔄 Transport Modes

The server supports three transport modes:

  • STDIO (default): Standard input/output for local tools and Claude Desktop
  • SSE: Server-Sent Events for web-based deployments
  • HTTP: Streamable HTTP for modern web deployments and microservices

🔒 Security Protection

The server includes comprehensive security protection with secure defaults that protect against common web-based attacks while preserving full MCP functionality when using HTTP transport.

🛡️ DNS Rebinding Protection

TrustedHost Middleware validates Host headers to prevent DNS rebinding attacks:

Secure by Default:

  • Only localhost and 127.0.0.1 hosts are allowed by default
  • Malicious websites cannot trick browsers into accessing your local server

Environment Variable:

export NEO4J_MCP_SERVER_ALLOWED_HOSTS="example.com,www.example.com"

🌐 CORS Protection

Cross-Origin Resource Sharing (CORS) protection blocks browser-based requests by default:

Environment Variable:

export NEO4J_MCP_SERVER_ALLOW_ORIGINS="https://example.com,https://example.com"

🔧 Complete Security Configuration

Development Setup:

mcp-neo4j-aura-manager --transport http \
  --allowed-hosts "localhost,127.0.0.1" \
  --allow-origins "http://localhost:3000"

Production Setup:

mcp-neo4j-aura-manager --transport http \
  --allowed-hosts "example.com,www.example.com" \
  --allow-origins "https://example.com,https://example.com"

🚨 Security Best Practices

For allow_origins:

  • Be specific: ["https://example.com", "https://example.com"]
  • Never use "*" in production with credentials
  • Use HTTPS origins in production

For allowed_hosts:

  • Include your actual domain: ["example.com", "www.example.com"]
  • Include localhost only for development
  • Never use "*" unless you understand the risks

🐳 Docker Deployment

The Neo4j Aura Manager MCP server can be deployed using Docker for remote deployments. Docker deployment should use HTTP transport for web accessibility. In order to integrate this deployment with applications like Claude Desktop, you will have to use a proxy in your MCP configuration such as mcp-remote.

🐳 Using with Docker for Claude Desktop

Here we use the Docker Hub hosted Aura Manager MCP server image with stdio transport for use with Claude Desktop.

Config details:

  • -i: Interactive mode - keeps STDIN open for stdio transport communication
  • --rm: Automatically remove container when it exits (cleanup)
  • -p 8000:8000: Port mapping - maps host port 8000 to container port 8000
  • NEO4J_TRANSPORT=stdio: Uses stdio transport for Claude Desktop compatibility
  • NEO4J_AURA_CLIENT_ID and NEO4J_AURA_CLIENT_SECRET: Your Aura API credentials

🌐 SSE Transport for Legacy Web Access

When using SSE transport (for legacy web clients), the server exposes an HTTP endpoint:

# Start the server with SSE transport
docker run -d -p 8000:8000 \
  -e NEO4J_AURA_CLIENT_ID="your-client-id" \
  -e NEO4J_AURA_CLIENT_SECRET="your-client-secret" \
  -e NEO4J_TRANSPORT="sse" \
  -e NEO4J_MCP_SERVER_HOST="0.0.0.0" \
  -e NEO4J_MCP_SERVER_PORT="8000" \
  --name neo4j-aura-mcp-server \
  mcp-neo4j-aura-manager:latest

# Test the SSE endpoint
curl http://localhost:8000/sse

# Use with MCP Inspector
npx @modelcontextprotocol/inspector http://localhost:8000/sse

🔗 Claude Desktop Integration with Docker

For Claude Desktop integration with a Dockerized server using http transport:

{
  "mcpServers": {
    "neo4j-aura-docker": {
      "command": "npx",
      "args": ["-y", "mcp-remote@latest", "http://localhost:8000/mcp/"]
    }
  }
}

Note: First start your Docker container with HTTP transport, then Claude Desktop can connect to it via the HTTP endpoint and proxy server like mcp-remote.
