# Performance Tier: A (Previously: F)
```

## 🏁 Quick Start (For Judges)

**1-Minute Setup & Verification:**

```bash
# 1. Clone and enter directory
git clone https://github.com/leksval/canrun
cd canrun

# 2. Install dependencies with uv (recommended)
uv sync

# 3. Test the official G-Assist protocol
python test/test_official_g_assist_protocol.py
# Expected: All tests PASSING with official protocol

# 4. Test enhanced G-Assist plugin
uv run python plugin.py --function check_compatibility --game "Diablo 4" --show-steam
# Expected: Enhanced G-Assist response with Steam Compare UI

# 5. Test natural language auto-detection

# Expected: Automatic routing to compatibility check
```

**Enhanced G-Assist Voice Commands (v5.1 Ready):**
- "Can my system run Diablo 4?" → Enhanced compatibility check with Steam Compare UI
- "Check compatibility for Cyberpunk 2077" → Full compatibility analysis with optimization tips
- "What are my system specs?" → Gaming-focused hardware detection with performance assessment
- "Compare Cyberpunk vs Elden Ring" → Multi-game performance comparison

## 📦 G-Assist Plugin Installation

### Ready-to-Use Executable
The G-Assist plugin is available as a pre-built executable in the root directory:
- **Executable**: [`plugin.exe`](plugin.exe) - Ready for G-Assist installation
- **Installer**: [`install_plugin.bat`](install_plugin.bat) - Automated installation script

### Quick Installation
```bash
# Run the automated installer
.\install_plugin.bat

# This will:
# 1. Create %USERPROFILE%\canrun\ directory
# 2. Copy canrun-g-assist-plugin.exe and required files
# 3. Install data files and dependencies
# 4. Test the plugin functionality
```

### **🚀 READY FOR G-ASSIST INTEGRATION**

**Next Steps for Users:**
1. **Rebuild Plugin**: `pyinstaller --onefile --name plugin --distpath . plugin.py`
2. **Install Plugin**: `.\install_plugin.bat` (as Administrator)  
3. **Test with G-Assist**: "Hey canrun, can I run Diablo 4?"

## 🤖 MCP Server Functionality (NEW!)

CanRun now includes a full-featured **Model Context Protocol (MCP) server** that allows G-Assist to directly integrate with the CanRun compatibility engine. This provides seamless AI-assisted game compatibility checking through the official NVIDIA MCP standard.

### MCP Tools and Capabilities

The MCP server exposes the following tools to G-Assist:

- **check_game_compatibility**: Analyze if a specific game can run on the current system
  - Input: Game name (e.g., "Diablo 4")
  - Output: Detailed compatibility analysis with performance tier

- **detect_hardware**: Provides comprehensive hardware detection for gaming systems
  - Output: Detailed hardware specifications focused on gaming performance

### Running the MCP Server

```bash
# Start the MCP server with auto port discovery
python app.py

# The server will be available at:
# http://localhost:xxxx (where xxxx is an available port)
```

### G-Assist MCP Integration

G-Assist can automatically discover and use the CanRun MCP server when both are running. This enables advanced conversational interactions like:

- "G-Assist, ask CanRun if I can play Starfield"
- "G-Assist, check if my system meets Diablo 4 requirements"
- "G-Assist, what's my gaming hardware like?"
