## 🎯 Ready for Production

### Local Development ✅
```bash
# Start local server
mcp-proxy --port 8080 --debug node ./bin/agentic-control-framework-mcp --workspaceRoot $(pwd)

# Test health
curl http://localhost:8080/health
```

### Docker Deployment ✅
```bash
# Deploy locally with Docker
./quick-deploy.sh local --proxy-only
```

### GCP Deployment (Setup Required)
```bash
# 1. Authenticate with GCP
gcloud auth login

# 2. Set project
gcloud config set project YOUR_PROJECT_ID

# 3. Enable APIs
gcloud services enable run.googleapis.com

# 4. Deploy
export GCP_PROJECT_ID=your-project-id
./quick-deploy.sh gcp --with-auth
```

## 🔧 Client Configuration

### Cursor
Add to settings.json:
```json
{
  "mcp.servers": {
    "acf-local": {
      "url": "http://localhost:8080/sse",
      "transport": "sse"
    }
  }
}
```

### Claude Desktop
Add to `~/Library/Application Support/Claude/claude_desktop_config.json`:
```json
{
  "mcpServers": {
    "acf-local": {
      "url": "http://localhost:8080/sse",
      "transport": "sse"
    }
  }
}
```

## 🚀 Next Steps

1. **For Local Development**: Use the local configurations above
2. **For GCP Deployment**: Complete GCP setup and run deployment
3. **For Client Testing**: Add configurations to your preferred MCP client
4. **For Production**: Set up authentication and monitoring

Your ACF MCP-proxy integration is ready! 🎉
