Configuration

Claude Desktop Configuration

Add the following to your Claude Desktop configuration file:

Windows

Edit %APPDATA%\Claude\claude_desktop_config.json:

{
  "mcpServers": {
    "system-diagnostics": {
      "command": "C:\\path\\to\\venv\\Scripts\\python.exe",
      "args": ["-m", "system_diagnostics_mcp.server"],
      "cwd": "C:\\path\\to\\system-diagnostics-mcp",
      "env": {
        "PYTHONPATH": "C:\\path\\to\\system-diagnostics-mcp"
      }
    }
  }
}

macOS

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "system-diagnostics": {
      "command": "/path/to/venv/bin/python",
      "args": ["-m", "system_diagnostics_mcp.server"],
      "cwd": "/path/to/system-diagnostics-mcp",
      "env": {
        "PYTHONPATH": "/path/to/system-diagnostics-mcp"
      }
    }
  }
}

Linux

Edit ~/.config/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "system-diagnostics": {
      "command": "/path/to/venv/bin/python",
      "args": ["-m", "system_diagnostics_mcp.server"],
      "cwd": "/path/to/system-diagnostics-mcp",
      "env": {
        "PYTHONPATH": "/path/to/system-diagnostics-mcp"
      }
    }
  }
}

Usage Examples

Once configured, you can interact with the system diagnostics server through Claude:

Basic System Check

"What's my current system status?"
"Show me CPU and memory usage"
"How much disk space do I have left?"

Performance Analysis

"My system is running slow, can you diagnose why?"
"Which applications are using the most memory?"
"Are there any performance bottlenecks?"

Battery and Power (Laptops)

"Why is my battery draining so fast?"
"Which apps are consuming the most power?"
"What's my current battery status?"

Hardware Recommendations

"I want to upgrade my system for gaming, what should I upgrade?"
"What hardware changes would improve my development workflow?"
"Should I add more RAM or upgrade my CPU?"

Application Management

"What applications are installed on my system?"
"Show me all running processes sorted by CPU usage"
"Which processes are using network bandwidth?"

Hardware and System Information

"What motherboard do I have?"
"What's my computer model and manufacturer?"
"How many RAM slots does my motherboard have?"
"What's the maximum RAM my system supports?"
"What BIOS version am I running?"
"Can I add more RAM to my system?"
"What memory slots are currently occupied?"
"Show me my motherboard specifications"
"What's my system's serial number?"
"What type of memory does my system use (DDR3/DDR4/DDR5)?"

Available Tools

Permissions

Some features may require elevated permissions:

• Windows: Run as Administrator for complete system access
• macOS: Grant Terminal/Python full disk access in System Preferences
• Linux: Some features may require sudo access

Troubleshooting

Common Issues

1. ImportError for psutil

   pip install --upgrade psutil
   

2. Windows: WMI errors

   pip install --upgrade wmi pywin32
   

3. Permission denied errors

   • Run with appropriate privileges
   • Check file system permissions

4. MCP connection issues

   • Verify the path in Claude Desktop config
   • Ensure Python virtual environment is activated
   • Check that the server starts without errors

Security Considerations

• The server has read-only access to system information
• No sensitive data (passwords, keys) is collected
• Network monitoring shows only connection metadata
• Application listing doesn't include user data
