+# Zen MCP Server - Docker Setup
+
+## Quick Start
+
+### 1. Prerequisites
+
+- Docker installed (Docker Compose optional)
+- At least one API key (Gemini, OpenAI, xAI, etc.)
+
+### 2. Configuration
+
+```bash
+# Copy environment template
+cp .env.example .env
+
+# Edit with your API keys (at least one required)
+# Required: GEMINI_API_KEY or OPENAI_API_KEY or XAI_API_KEY
+nano .env
+```
+
+### 3. Build Image
+
+```bash
+# Build the Docker image
+docker build -t zen-mcp-server:latest .
+
+# Or use the build script (Bash)
+chmod +x docker/scripts/build.sh
+./docker/scripts/build.sh
+
+# Build with PowerShell
+docker/scripts/build.ps1
+
+```
+
+### 4. Usage Options
+
+#### A. Direct Docker Run (Recommended for MCP)
+
+```bash
+# Run with environment file
+docker run --rm -i --env-file .env \
+  -v $(pwd)/logs:/app/logs \
+  zen-mcp-server:latest
+
+# Run with inline environment variables
+docker run --rm -i \
+  -e GEMINI_API_KEY="your_key_here" \
+  -e LOG_LEVEL=INFO \
+  -v $(pwd)/logs:/app/logs \
+  zen-mcp-server:latest
+```
+
+#### B. Docker Compose (For Development/Monitoring)
+
+```bash
+# Deploy with Docker Compose
+chmod +x docker/scripts/deploy.sh
+./docker/scripts/deploy.sh
+
+# Or use PowerShell script
+docker/scripts/deploy.ps1
+
+# Interactive stdio mode
+docker-compose exec zen-mcp python server.py
+```
+
+## Service Management
+
+### Docker Commands
+
+```bash
+# View running containers
+docker ps
+
+# View logs from container
+docker logs <container_id>
+
+# Stop all zen-mcp containers
+docker stop $(docker ps -q --filter "ancestor=zen-mcp-server:latest")
+
+# Remove old containers and images
+docker container prune
+docker image prune
+```
+
+### Docker Compose Management (Optional)
+
+```bash
+# View logs
+docker-compose logs -f zen-mcp
+
+# Check status
+docker-compose ps
+
+# Restart service
+docker-compose restart zen-mcp
+
+# Stop services
+docker-compose down
+
+# Rebuild and update
+docker-compose build --no-cache zen-mcp
+docker-compose up -d zen-mcp
+```
+
+## Health Monitoring
+
+The container includes health checks that verify:
+- Server process is running
+- Python modules can be imported
+- Log directory is writable  
+- API keys are configured
+
+## Volumes and Persistent Data
+
+The Docker setup includes persistent volumes to preserve data between container runs:
+
+- **`./logs:/app/logs`** - Persistent log storage (local folder mount)
+- **`zen-mcp-config:/app/conf`** - Configuration persistence (named Docker volume)
+- **`/etc/localtime:/etc/localtime:ro`** - Host timezone synchronization (read-only)
+
+### How Persistent Volumes Work
+
+The `zen-mcp` service (used by `zen-docker-compose` and Docker Compose commands) mounts the named volume `zen-mcp-config` persistently. All data placed in `/app/conf` inside the container is preserved between runs thanks to this Docker volume.
+
+In the `docker-compose.yml` file, you will find:
+
+```yaml
+volumes:
+  - ./logs:/app/logs
+  - zen-mcp-config:/app/conf
+  - /etc/localtime:/etc/localtime:ro
+```
+
+and the named volume definition:
+
+```yaml
+volumes:
+  zen-mcp-config:
+    driver: local
+```
+
+## Security
+
+- Runs as non-root user `zenuser`
+- Read-only filesystem with tmpfs for temporary files
+- No network ports exposed (stdio communication only)
+- Secrets managed via environment variables
+
+## Troubleshooting
+
+### Container won't start
+
+```bash
+# Check if image exists
+docker images zen-mcp-server
+
+# Test container interactively
+docker run --rm -it --env-file .env zen-mcp-server:latest bash
+
+# Check environment variables
+docker run --rm --env-file .env zen-mcp-server:latest env | grep API
+
+# Test with minimal configuration
+docker run --rm -i -e GEMINI_API_KEY="test" zen-mcp-server:latest python server.py
+```
+
+### MCP Connection Issues
+
+```bash
+# Test Docker connectivity
+docker run --rm hello-world
+
+# Verify container stdio
+echo '{"jsonrpc": "2.0", "method": "ping"}' | docker run --rm -i --env-file .env zen-mcp-server:latest python server.py
+
+# Check Claude Desktop logs for connection errors
+```
+
+### API Key Problems
+
+```bash
+# Verify API keys are loaded
+docker run --rm --env-file .env zen-mcp-server:latest python -c "import os; print('GEMINI_API_KEY:', bool(os.getenv('GEMINI_API_KEY')))"
+
+# Test API connectivity
+docker run --rm --env-file .env zen-mcp-server:latest python /usr/local/bin/healthcheck.py
+```
+
+### Permission Issues
+
+```bash
+# Fix log directory permissions (Linux/macOS)
+sudo chown -R $USER:$USER logs/
+chmod 755 logs/
+
+# Windows: Run Docker Desktop as Administrator if needed
+```
+
+### Memory/Performance Issues
+
+```bash
+# Check container resource usage
+docker stats
+
+# Run with memory limits
+docker run --rm -i --memory="512m" --env-file .env zen-mcp-server:latest
+
+# Monitor Docker logs
+docker run --rm -i --env-file .env zen-mcp-server:latest 2>&1 | tee docker.log
+```
+
+## MCP Integration (Claude Desktop)
+
+### Recommended Configuration (docker run)
+
+```json
+{
+  "servers": {
+    "zen-docker": {
+      "command": "docker",
+      "args": [
+        "run",
+        "--rm",
+        "-i",
+        "--env-file",
+        "/absolute/path/to/zen-mcp-server/.env",
+        "-v",
+        "/absolute/path/to/zen-mcp-server/logs:/app/logs",
+        "zen-mcp-server:latest"
+      ]
+    }
+  }
+}
+```
+
+### Windows Example
+
+```json
+{
+  "servers": {
+    "zen-docker": {
+      "command": "docker",
+      "args": [
+        "run",
+        "--rm",
+        "-i",
+        "--env-file",
+        "C:/Users/YourName/path/to/zen-mcp-server/.env",
+        "-v",
+        "C:/Users/YourName/path/to/zen-mcp-server/logs:/app/logs",
+        "zen-mcp-server:latest"
+      ]
+    }
+  }
+}
+```
+
+### Advanced Option: docker-compose run (uses compose configuration)
+
+```json
+{
+  "servers": {
+    "zen-docker": {
+      "command": "docker-compose",
+      "args": [
+        "-f",
+        "/absolute/path/to/zen-mcp-server/docker-compose.yml",
+        "run",
+        "--rm",
+        "zen-mcp"
+      ]
+    }
+  }
+}
+```
+
+### Environment File Template
+
+Create a `.env` file with at least one API key:
+
+```bash
+# Required: At least one API key
+GEMINI_API_KEY=your_gemini_key_here
+OPENAI_API_KEY=your_openai_key_here
+
+# Optional configuration
+LOG_LEVEL=INFO
+DEFAULT_MODEL=auto
+DEFAULT_THINKING_MODE_THINKDEEP=high
+
+# Optional API keys (leave empty if not used)
+ANTHROPIC_API_KEY=
+XAI_API_KEY=
+DIAL_API_KEY=
+OPENROUTER_API_KEY=
+CUSTOM_API_URL=
+```
+
+## Quick Test & Validation
+
+### 1. Test Docker Image
+
+```bash
+# Test container starts correctly
+docker run --rm zen-mcp-server:latest python --version
+
+# Test health check
+docker run --rm -e GEMINI_API_KEY="test" zen-mcp-server:latest python /usr/local/bin/healthcheck.py
+```
+
+### 2. Test MCP Protocol
+
+```bash
+# Test basic MCP communication
+echo '{"jsonrpc": "2.0", "method": "initialize", "params": {}}' | \
+  docker run --rm -i --env-file .env zen-mcp-server:latest python server.py
+```
+
+### 3. Validate Configuration
+
+```bash
+# Run validation script
+python test_mcp_config.py
+
+# Or validate JSON manually
+python -m json.tool .vscode/mcp.json
+```
+
+## Available Tools
+
+The Zen MCP Server provides these tools when properly configured:
+
+- **chat** - General AI conversation and collaboration
+- **thinkdeep** - Multi-stage investigation and reasoning  
+- **planner** - Interactive sequential planning
+- **consensus** - Multi-model consensus workflow
+- **codereview** - Comprehensive code review
+- **debug** - Root cause analysis and debugging
+- **analyze** - Code analysis and assessment

+
+## Performance Notes
+
+- **Image size**: ~293MB optimized multi-stage build
+- **Memory usage**: ~256MB base + model overhead
+- **Startup time**: ~2-3 seconds for container initialization
+- **API response**: Varies by model and complexity (1-30 seconds)
+
+For production use, consider:
+- Using specific API keys for rate limiting
+- Monitoring container resource usage
+- Setting up log rotation for persistent logs
+- Using Docker health checks for reliability

+# Docker Deployment Guide
+
+This guide covers deploying Zen MCP Server using Docker and Docker Compose for production environments.
+
+## Quick Start
+
+1. **Clone the repository**:
+   ```bash
+   git clone https://github.com/BeehiveInnovations/zen-mcp-server.git
+   cd zen-mcp-server
+   ```
+
+2. **Configure environment variables**:
+   ```bash
+   cp .env.example .env
+   # Edit .env with your API keys
+   ```
+
+3. **Deploy with Docker Compose**:
+   ```bash
+   # Linux/macOS
+   ./docker/scripts/deploy.sh
+   
+   # Windows PowerShell
+   .\docker\scripts\deploy.ps1
+   ```
+
+## Environment Configuration
+
+### Required API Keys
+
+At least one API key must be configured in your `.env` file:
+
+```env
+# Google Gemini (Recommended)
+GEMINI_API_KEY=your_gemini_api_key_here
+
+# OpenAI
+OPENAI_API_KEY=your_openai_api_key_here
+
+# X.AI GROK
+XAI_API_KEY=your_xai_api_key_here
+
+# OpenRouter (unified access)
+OPENROUTER_API_KEY=your_openrouter_api_key_here
+
+# Additional providers
+DIAL_API_KEY=your_dial_api_key_here
+DIAL_API_HOST=your_dial_host
+```
+
+### Optional Configuration
+
+```env
+# Default model selection
+DEFAULT_MODEL=auto
+
+# Logging
+LOG_LEVEL=INFO
+LOG_MAX_SIZE=10MB
+LOG_BACKUP_COUNT=5
+
+# Advanced settings
+DEFAULT_THINKING_MODE_THINKDEEP=high
+DISABLED_TOOLS=
+MAX_MCP_OUTPUT_TOKENS=
+
+# Timezone
+TZ=UTC
+```
+
+## Deployment Scripts
+
+### Linux/macOS Deployment
+
+Use the provided bash script for robust deployment:
+
+```bash
+./docker/scripts/deploy.sh
+```
+
+**Features:**
+- ✅ Environment validation
+- ✅ Exponential backoff health checks
+- ✅ Automatic log management
+- ✅ Service status monitoring
+
+### Windows PowerShell Deployment
+
+Use the PowerShell script for Windows environments:
+
+```powershell
+.\docker\scripts\deploy.ps1
+```
+
+**Additional Options:**
+```powershell
+# Skip health check
+.\docker\scripts\deploy.ps1 -SkipHealthCheck
+
+# Custom timeout
+.\docker\scripts\deploy.ps1 -HealthCheckTimeout 120
+```
+
+## Docker Architecture
+
+### Multi-Stage Build
+
+The Dockerfile uses a multi-stage build for optimal image size:
+
+1. **Builder Stage**: Installs dependencies and creates virtual environment
+2. **Runtime Stage**: Copies only necessary files for minimal footprint
+
+### Security Features
+
+- **Non-root user**: Runs as `zenuser` (UID/GID 1000)
+- **Read-only filesystem**: Container filesystem is immutable
+- **No new privileges**: Prevents privilege escalation
+- **Secure tmpfs**: Temporary directories with strict permissions
+
+### Resource Management
+
+Default resource limits:
+```yaml
+deploy:
+  resources:
+    limits:
+      memory: 512M
+      cpus: '0.5'
+    reservations:
+      memory: 256M
+      cpus: '0.25'
+```
+
+## Service Management
+
+### Starting the Service
+
+```bash
+# Start in background
+docker-compose up -d
+
+# Start with logs
+docker-compose up
+```
+
+### Monitoring
+
+```bash
+# View service status
+docker-compose ps
+
+# Follow logs
+docker-compose logs -f zen-mcp
+
+# View health status
+docker inspect zen-mcp-server --format='{{.State.Health.Status}}'
+```
+
+### Stopping the Service
+
+```bash
+# Graceful stop
+docker-compose down
+
+# Force stop
+docker-compose down --timeout 10
+```
+
+## Health Checks
+
+The container includes comprehensive health checks:
+
+- **Process check**: Verifies server.py is running
+- **Import check**: Validates critical Python modules
+- **Directory check**: Ensures log directory is writable
+- **API check**: Tests provider connectivity
+
+Health check configuration:
+```yaml
+healthcheck:
+  test: ["CMD", "python", "/usr/local/bin/healthcheck.py"]
+  interval: 30s
+  timeout: 10s
+  retries: 3
+  start_period: 40s
+```
+
+## Persistent Data
+
+### Volumes
+
+- **Logs**: `./logs:/app/logs` - Application logs
+- **Config**: `zen-mcp-config:/app/conf` - Configuration persistence
+- **Time sync**: `/etc/localtime:/etc/localtime:ro` - Host timezone sync
+
+**Note:** The `zen-mcp-config` is a named Docker volume that persists configuration data between container restarts. All data placed in `/app/conf` inside the container is preserved thanks to this persistent volume. This applies to both `docker-compose run` and `docker-compose up` commands.
+
+### Log Management
+
+Logs are automatically rotated with configurable retention:
+
+```env
+LOG_MAX_SIZE=10MB      # Maximum log file size
+LOG_BACKUP_COUNT=5     # Number of backup files to keep
+```
+
+## Networking
+
+### Default Configuration
+
+- **Network**: `zen-network` (bridge)
+- **Subnet**: `172.20.0.0/16`
+- **Isolation**: Container runs in isolated network
+
+### Port Exposure
+
+By default, no ports are exposed. The MCP server communicates via stdio when used with Claude Desktop or other MCP clients.
+
+For external access (advanced users):
+```yaml
+ports:
+  - "3000:3000"  # Add to service configuration if needed
+```
+
+## Troubleshooting
+
+### Common Issues
+
+**1. Health check failures:**
+```bash
+# Check logs
+docker-compose logs zen-mcp
+
+# Manual health check
+docker exec zen-mcp-server python /usr/local/bin/healthcheck.py
+```
+
+**2. Permission errors:**
+```bash
+# Fix log directory permissions
+sudo chown -R 1000:1000 ./logs
+```
+
+**3. Environment variables not loaded:**
+```bash
+# Verify .env file exists and is readable
+ls -la .env
+cat .env
+```
+
+**4. API key validation errors:**
+```bash
+# Check environment variables in container
+docker exec zen-mcp-server env | grep -E "(GEMINI|OPENAI|XAI)"
+```
+
+### Debug Mode
+
+Enable verbose logging for troubleshooting:
+
+```env
+LOG_LEVEL=DEBUG
+```
+
+## Production Considerations
+
+### Security
+
+1. **Use Docker secrets** for API keys in production:
+   ```yaml
+   secrets:
+     gemini_api_key:
+       external: true
+   ```
+
+2. **Enable AppArmor/SELinux** if available
+
+3. **Regular security updates**:
+   ```bash
+   docker-compose pull
+   docker-compose up -d
+   ```
+
+### Monitoring
+
+Consider integrating with monitoring solutions:
+
+- **Prometheus**: Health check metrics
+- **Grafana**: Log visualization
+- **AlertManager**: Health status alerts
+
+### Backup
+
+Backup persistent volumes:
+```bash
+# Backup configuration
+docker run --rm -v zen-mcp-config:/data -v $(pwd):/backup alpine tar czf /backup/config-backup.tar.gz -C /data .
+
+# Restore configuration
+docker run --rm -v zen-mcp-config:/data -v $(pwd):/backup alpine tar xzf /backup/config-backup.tar.gz -C /data
+```
+
+## Performance Tuning
+
+### Resource Optimization
+
+Adjust limits based on your workload:
+
+```yaml
+deploy:
+  resources:
+    limits:
+      memory: 1G        # Increase for heavy workloads
+      cpus: '1.0'       # More CPU for concurrent requests
+```
+
+### Memory Management
+
+Monitor memory usage:
+```bash
+docker stats zen-mcp-server
+```
+
+Adjust Python memory settings if needed:
+```env
+PYTHONMALLOC=pymalloc
+MALLOC_ARENA_MAX=2
+```
+
+## Integration with Claude Desktop
+
+Configure Claude Desktop to use the containerized server. **Choose one of the configurations below based on your needs:**
+
+### Option 1: Direct Docker Run (Recommended)
+
+**The simplest and most reliable option for most users.**
+
+```json
+{
+  "mcpServers": {
+    "zen-mcp": {
+      "command": "docker",
+      "args": [
+        "run",
+        "--rm",
+        "-i",
+        "--env-file",
+        "/absolute/path/to/zen-mcp-server/.env",
+        "-v",
+        "/absolute/path/to/zen-mcp-server/logs:/app/logs",
+        "zen-mcp-server:latest"
+      ]
+    }
+  }
+}
+```
+
+**Exemple Windows** :
+```json
+{
+  "mcpServers": {
+    "zen-mcp": {
+      "command": "docker",
+      "args": [
+        "run",
+        "--rm",
+        "-i",
+        "--env-file",
+        "C:/path/to/zen-mcp-server/.env",
+        "-v",
+        "C:/path/to/zen-mcp-server/logs:/app/logs",
+        "zen-mcp-server:latest"
+      ]
+    }
+  }
+}
+```
+
+### Option 2: Docker Compose Run (one-shot, uses docker-compose.yml)
+
+**To use the advanced configuration from docker-compose.yml without a persistent container.**
+
+```json
+{
+  "mcpServers": {
+    "zen-mcp": {
+      "command": "docker-compose",
+      "args": [
+        "-f", "/absolute/path/to/zen-mcp-server/docker-compose.yml",
+        "run", "--rm", "zen-mcp"
+      ]
+    }
+  }
+}
+```
+
+### Option 3: Inline Environment Variables (Advanced)
+
+**For highly customized needs.**
+
+```json
+{
+  "mcpServers": {
+    "zen-mcp": {
+      "command": "docker",
+      "args": [
+        "run",
+        "--rm",
+        "-i",
+        "-e", "GEMINI_API_KEY=your_key_here",
+        "-e", "LOG_LEVEL=INFO",
+        "-e", "DEFAULT_MODEL=auto",
+        "-v", "/path/to/logs:/app/logs",
+        "zen-mcp-server:latest"
+      ]
+    }
+  }
+}
+```
+
+### Configuration Notes
+
+**Important notes:**
+- Replace `/absolute/path/to/zen-mcp-server` with the actual path to your project.
+- Always use forward slashes `/` for Docker volumes, even on Windows.
+- Ensure the `.env` file exists and contains your API keys.
+- **Persistent volumes**: Docker Compose options (Options 2) automatically use the `zen-mcp-config` named volume for persistent configuration storage.
+
+**Environment file requirements:**
+```env
+# At least one API key is required
+GEMINI_API_KEY=your_gemini_key
+OPENAI_API_KEY=your_openai_key
+# ... other keys
+```
+
+**Troubleshooting:**
+- If Option 1 fails: check that the Docker image exists (`docker images zen-mcp-server`).
+- If Option 2 fails: verify the compose file path and ensure the service is not already in use.
+- Permission issues: make sure the `logs` folder is writable.
+
+## Advanced Configuration
+
+### Custom Networks
+
+For complex deployments:
+```yaml
+networks:
+  zen-network:
+    driver: bridge
+      ipam:
+        config:
+          - subnet: 172.20.0.0/16
+            gateway: 172.20.0.1
+```
+
+### Multiple Instances
+
+Run multiple instances with different configurations:
+```bash
+# Copy compose file
+cp docker-compose.yml docker-compose.dev.yml
+
+# Modify service names and ports
+# Deploy with custom compose file
+docker-compose -f docker-compose.dev.yml up -d
+```
+
+## Migration and Updates
+
+### Updating the Server
+
+```bash
+# Pull latest changes
+git pull origin main
+
+# Rebuild and restart
+docker-compose down
+docker-compose build --no-cache
+./docker/scripts/deploy.sh
+```
+
+### Data Migration
+
+When upgrading, configuration is preserved in the named volume `zen-mcp-config`.
+
+For major version upgrades, check the [CHANGELOG](../CHANGELOG.md) for breaking changes.
+
+## Support
+
+For any questions, open an issue on GitHub or consult the official documentation.
+
+
+---
+
+**Next Steps:**
+- Review the [Configuration Guide](configuration.md) for detailed environment variable options
+- Check [Advanced Usage](advanced-usage.md) for custom model configurations
+- See [Troubleshooting](troubleshooting.md) for common issues and solutions

+# Cross-Platform Compatibility Patches
+
+This directory contains patch scripts to improve the cross-platform compatibility of the zen-mcp server.
+
+## Files
+
+### `patch_crossplatform.py`
+Main script that automatically applies all necessary fixes to resolve cross-platform compatibility issues.
+
+**Usage:**
+```bash
+# From the patch/ directory
+python patch_crossplatform.py [--dry-run] [--backup] [--validate-only]
+```
+
+**Options:**
+- `--dry-run`: Show changes without applying them
+- `--backup`: Create a backup before modifying files
+- `--validate-only`: Only check if the fixes are already applied
+
+### `validation_crossplatform.py`
+Validation script that tests whether all fixes work correctly.
+
+**Usage:**
+```bash
+# From the patch/ directory
+python validation_crossplatform.py
+```
+
+## Applied Fixes
+
+1. **HOME DIRECTORY DETECTION ON WINDOWS:**
+   - Linux tests (/home/ubuntu) failed on Windows
+   - Unix patterns were not detected due to backslashes
+   - Solution: Added Windows patterns + double path check
+
+2. **UNIX PATH VALIDATION ON WINDOWS:**
+   - Unix paths (/etc/passwd) were rejected as relative paths
+   - Solution: Accept Unix paths as absolute on Windows
+
+3. **CROSS-PLATFORM TESTS:**
+   - Assertions used OS-specific separators
+   - The safe_files test used a non-existent file on Windows
+   - Solution: Use Path.parts + temporary files on Windows
+
+4. **SHELL SCRIPT COMPATIBILITY ON WINDOWS:**
+   - Shell scripts did not detect Windows virtual environment paths
+   - Solution: Added detection for .zen_venv/Scripts/ paths
+
+5. **COMMUNICATION SIMULATOR LOGGER BUG:**
+   - AttributeError: logger used before initialization
+   - Solution: Initialize logger before calling _get_python_path()
+
+6. **PYTHON PATH DETECTION ON WINDOWS:**
+   - The simulator could not find the Windows Python executable
+   - Solution: Added Windows-specific detection
+
+## How to Use
+
+1. **Apply all fixes:**
+   ```bash
+   cd patch/
+   python patch_crossplatform.py
+   ```
+
+2. **Test in dry-run mode (preview):**
+   ```bash
+   cd patch/
+   python patch_crossplatform.py --dry-run
+   ```
+
+3. **Validate the fixes:**
+   ```bash
+   cd patch/
+   python validation_crossplatform.py
+   ```
+
+4. **Check if fixes are already applied:**
+   ```bash
+   cd patch/
+   python patch_crossplatform.py --validate-only
+   ```
+
