+# 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.docker.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
+chmod +x docker/scripts/build.sh
+./docker/scripts/build.sh
+```
+
+### 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
+
+# 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
+
+- `./logs:/app/logs` - Persistent log storage
+- `zen-mcp-config:/app/conf` - Configuration persistence
+
+## 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)
+
+### Configuration File Setup
+
+Add to your Claude Desktop MCP configuration:
+
+```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",
+        "python",
+        "server.py"
+      ],
+      "env": {
+        "DOCKER_BUILDKIT": "1"
+      }
+    }
+  }
+}
+```
+
+### Windows MCP Configuration
+
+For Windows users, use forward slashes in paths:
+
+```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",
+        "python",
+        "server.py"
+      ],
+      "env": {
+        "DOCKER_BUILDKIT": "1"
+      }
+    }
+  }
+}
+```
+
+### Environment File Template
+
+Create `.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
+- **refactor** - Refactoring analysis and suggestions
+- **secaudit** - Security audit workflow
+- **testgen** - Test generation with edge cases
+- **docgen** - Documentation generation
+- **tracer** - Code tracing and dependency mapping
+- **precommit** - Pre-commit validation workflow
+- **listmodels** - Available AI models information
+- **version** - Server version and configuration
+
+## 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
