Jonathan Hefner 61cd4ed219 Use content instead of structuredContent in examples Not all MCP clients support structuredContent in MCP tool results, so examples now return data as JSON in content and parse it client-side. Pattern used: - Server: content: [{ type: "text", text: JSON.stringify(data) }] - Client: JSON.parse(result.content!.filter(...).map(...).join("")) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>		2025-12-05 16:35:20 -06:00

Example: System Monitor App

A demo MCP App that displays real-time OS metrics with a stacked area chart for per-core CPU usage and a bar gauge for memory.

Features

Per-Core CPU Monitoring: Stacked area chart showing individual CPU core utilization over a 1-minute sliding window
Memory Usage: Horizontal bar gauge with color-coded thresholds (green/yellow/red)
System Info: Hostname, platform, and uptime display
Auto-Polling: Automatically starts monitoring on load with 2-second refresh interval
Theme Support: Adapts to light/dark mode preferences

Install dependencies:
```
npm install
```
Build and start the server:
```
npm start
