System Resource Monitor MCP Server

An MCP server that provides Claude with real-time system monitoring capabilities, including CPU, memory, disk, network, battery, and internet speed metrics using systeminformation and multi-source speed tests.

Tools

• get_cpu_usage

  • Retrieves the current CPU load as a percentage, including overall and per-core usage.
  • Inputs: None
  • Output: Text (e.g., CPU Load: 12.34% (Cores: 10.50, 15.20, 8.90, 14.60%))

• get_memory_usage

  • Reports total, used, and free memory in GB, plus percentage used.
  • Inputs: None
  • Output: Text (e.g., Memory: 65.43% used (7.82GB / 16.00GB))

• get_disk_space

  • Shows disk usage for the largest drive in GB and percentage.
  • Inputs: None
  • Output: Text (e.g., Disk (/): 78.90% used (189.50GB / 250.00GB))

• get_network_usage

  • Returns real-time network RX/TX rates (KB/s) and total data since boot (MB).
  • Inputs: None
  • Output: Text (e.g., Network (eth0): RX: 25.50KB/s, TX: 10.20KB/s (Total: RX 150.34MB, TX 75.89MB))

• get_battery_status

  • Provides battery charge percentage, charging status, and time remaining (if applicable).
  • Inputs: None
  • Output: Text (e.g., Battery: 85% (charging), 120 min remaining or No battery detected)

• get_internet_speed

  • Measures internet speed using multiple download sources (including a user-uploaded file) and upload tests, returning median speeds in Mbps.
  • Inputs: None
  • Output: Text (e.g., Internet Speed: Download 45.67Mbps, Upload 8.45Mbps)

Configuration

Step 1: Clone and Install

Clone this repository:

git clone git@github.com:abhinav7895/system-mcp.git

Navigate to the directory and install dependencies:

cd system-resource-monitor && npm install

Step 2: Build the Project

Compile the TypeScript code:

npm run build

This generates the dist/index.js file, ready to run as an MCP server.

Step 3: Configure Claude Desktop

1. Download Claude Desktop here.
2. Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "system-resource-monitor": {
      "command": "node",
      "args": ["/absolute/path/to/dist/index.js"]
    }
  }
}

Access the config file:

vim ~/Library/Application\ Support/Claude/claude_desktop_config.json

(Adjust the path to dist/index.js based on your project location.)

Step 4: Testing

Ensure Claude Desktop recognizes the tools by checking for the hammer icon:

!Claude Visual Tools

Click the hammer icon to see available tools:

!Available Integration

If all six tools (get_cpu_usage, get_memory_usage, etc.) appear, the integration is active. You can now ask questions like:

• "What’s my CPU usage?"
• "How fast is my internet?"

Step 5: Advanced Customization

• Internet Speed Test: Modify testUrls in index.ts to use different download sources or adjust uploadSizeBytes (default 80KB) for upload tests.
• Logging: Console logs provide detailed test output; disable them in production by removing console.log statements.

Troubleshooting

• Tool Not Showing: Verify the server is running (node dist/index.js) and the config path is correct.
• Internet Speed Errors: Ensure network connectivity and test URLs are accessible. Check console logs for specific failures.
• Refer to the MCP troubleshooting guide
