Gamedev MCP Hub

GameDev MCP Hub

Version: 1.0.0
Status: Production Ready
Build: ✅ Passing

A comprehensive Model Context Protocol (MCP) hub that aggregates 600+ game development tools through multiple MCP servers, providing a unified interface for AI assistants (Claude, LM Studio, etc.) with intelligent routing and skills integration.

🚀 Quick Start

Prerequisites

• Node.js 18+ (for the hub)
• Python 3.11+ (for Python-based servers like Meshy)
• Git (for GitHub integration)

Installation & Startup

# 1. Install dependencies
npm install

# 2. Configure environment
copy .env.example .env
# Edit .env and add your API keys

# 3. Start the hub (recommended)
START_ALL.bat

# Or start with browser auto-open
start-gui-with-browser.bat

The hub will automatically:

• ✅ Start the GUI dashboard on http://localhost:3100
• ✅ Connect to all enabled MCP servers
• ✅ Be ready for AI client connections on http://localhost:3000/sse

🔧 Configuration

Environment Variables

Create .env file with:

# Required for GitHub integration
GITHUB_TOKEN=ghp_your_token_here

# Optional: For enhanced features
MESHY_API_KEY=your_meshy_key_here
SENTRY_AUTH_TOKEN=your_sentry_token_here

Server Configuration

Edit config/mcp-servers.json to enable/disable servers:

{
  "servers": {
    "obsidian": {
      "enabled": true,
      "command": "path/to/mcp-server.exe"
    },
    "meshy": {
      "enabled": true,
      "command": "python",
      "args": ["-m", "src.server"],
      "cwd": "external-servers/meshy-ai-mcp-server"
    }
  }
}

🧪 Testing

2. Open LM Studio: Load a model with large context (8K+ tokens)
3. Enable MCP: Toggle "gamedev-hub" in Program tab
4. Test: Ask "What tools do you have access to?"

See TEST_LM_STUDIO_NOW.md for detailed testing guide.

🐛 Troubleshooting

Hub Won't Start

Check prerequisites:

node --version  # Should be 18+
npm --version   # Should be 9+

Rebuild:

npm run build

Servers Not Connecting

Check logs:

logs/hub.log     # Main hub logs
logs/error.log   # Error logs

Test individual server:

# Test Blender server
blender --python path/to/blender-mcp/server.py

# Test Meshy server
cd external-servers/meshy-ai-mcp-server
python -m src.server

Port Already in Use

The hub automatically finds available ports (3100-3109). If all ports are in use:

# Find process using port 3100
netstat -ano | findstr "3100"

# Kill process by PID
taskkill /PID <pid> /F
