Enables comprehensive management of Dell PowerStore storage arrays, including storage volumes, host configuration, system health monitoring, network settings, and data protection rules.
Allows n8n automation platforms to programmatically interact with Dell PowerStore storage arrays by exposing MCP tools via an HTTP/SSE transport.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@Dell PowerStore MCP Serverlist all storage volumes and their health status"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Dell PowerStore MCP Server
A Model Context Protocol (MCP) server for Dell PowerStore that automatically generates tools from OpenAPI specifications with a credential-free architecture. Enables AI assistants like Claude and automation platforms like n8n to interact with PowerStore storage arrays.
β¨ Features
Feature | Description |
π Automatic Tool Generation | Dynamically generates 262+ MCP tools from Dell PowerStore OpenAPI specs |
π Credential-Free Architecture | No stored credentials - pass host/username/password with each tool call |
π Multi-Host Support | Manage multiple PowerStore instances from a single server |
π‘οΈ Safe Operations | GET-only operations for read-only PowerStore access |
π Multiple Transports | HTTP/SSE for n8n, stdio for Claude Desktop |
π Health Monitoring | Built-in health checks and metrics endpoints |
π³ Docker Ready | Production-ready container images |

βοΈ Configuration
Environment Variables
Variable | Description | Default |
| Logging level (debug, info, warning, error) |
|
| Log format (text, json) |
|
| Path to OpenAPI specification |
|
| HTTP server port |
|
| HTTP server host |
|
Example .env File
LOG_LEVEL=info
LOG_FORMAT=json
HTTP_PORT=3000β οΈ Important: PowerStore credentials are NOT stored in configuration. They are passed securely with each tool call.
π Usage
HTTP/SSE Mode (for n8n and Web Clients)
# Using the CLI
powerstore-mcp-http
# Using uvicorn directly
uvicorn powerstore_mcp.http_server:app --host 0.0.0.0 --port 3000
# Using the start script
./start-http.shThe server provides:
SSE Endpoint:
http://localhost:3000/sseHealth Check:
http://localhost:3000/healthMetrics:
http://localhost:3000/health(detailed JSON response)
stdio Mode (for Claude Desktop)
# Using the CLI
powerstore-mcp
# Using Python module
python -m powerstore_mcp.main
# Using the start script
./start-python.shDocker Compose
# Start the server
docker-compose up -d
# View logs
docker-compose logs -f
# Stop the server
docker-compose downπ Integration
n8n AI Agent
Add an MCP Client node to your n8n workflow
Configure the connection:
Transport: SSE
URL:
http://localhost:3000/sse
The 262 PowerStore tools will be available to AI agents
Claude Desktop
Add to your Claude Desktop configuration (claude_desktop_config.json):
{
"mcpServers": {
"dell-powerstore": {
"command": "powerstore-mcp",
"args": []
}
}
}Or with explicit Python path:
{
"mcpServers": {
"dell-powerstore": {
"command": "/path/to/venv/bin/python",
"args": ["-m", "powerstore_mcp.main"]
}
}
}Custom MCP Clients
import asyncio
from mcp import ClientSession
from mcp.client.sse import sse_client
async def main():
async with sse_client("http://localhost:3000/sse") as (read, write):
async with ClientSession(read, write) as session:
await session.initialize()
# List available tools
tools = await session.list_tools()
print(f"Found {len(tools.tools)} tools")
# Call a tool
result = await session.call_tool("getAppliance", {
"host": "powerstore.example.com",
"username": "admin",
"password": "password"
})
print(result)
asyncio.run(main())π§ Available Tools
The server dynamically generates 262 tools from the PowerStore OpenAPI specification.
Authentication Parameters
Every tool requires these authentication parameters:
Parameter | Type | Description |
| string | PowerStore hostname or IP |

| string | PowerStore password |
Tool Categories
Category | Example Tools | Description |
Storage |
| Volume and host management |
System |
| System information |

{host, user, pass} Basic Auth HeaderKey Design Principles
No Stored Credentials: Server starts without any PowerStore connection
Per-Request Auth: Each tool call includes host/username/password
Fresh Sessions: New API client created for each request
Multi-Host Ready: Easily manage multiple PowerStore instances
