+
+## Server Architecture
+
+This MCP server supports:
+- **stdio mode** (default): stdin/stdout for MCP clients.
+- **HTTP mode**: Web interface for HTML/browser access over LAN.
+- **Templates directory**: User-provided .docx templates for reuse and fill-in generation.
+- **High-fidelity PDF conversion**: Via LibreOffice (included in Docker image).

+## Docker Image
+
+There is now a single, unified Dockerfile that includes:
+- HTTP server (HTML interface)
+- stdio MCP transport
+- LibreOffice (high-fidelity PDF conversion)
+- Templates directory support
+- Sandboxed, non-root configuration
+
+Build:
+
+```bash
+docker build -t docx-mcp:full .
+```
+
+## Deployment
+
+### HTTP Mode (HTML Interface - LAN)
+
+Run the HTTP server with templates and output directories mounted:
+
+```bash
+docker run --rm \
+    --name docx-mcp-http \
+    -p 3000:3000 \
+    -v /host/path/templates:/templates:ro \
+    -v /host/path/output:/out \
+    -e DOCX_MCP_HTTP=true \
+    -e DOCX_MCP_HTTP_ADDRESS=0.0.0.0:3000 \
+    -e DOCX_MCP_TEMPLATES_DIR=/templates \
+    -e DOCX_MCP_MAX_SIZE=104857600 \
+    -e DOCX_MCP_MAX_DOCS=30 \
+    --memory 1g \
+    --cpus 1.5 \
+    docx-mcp:full
+```
+
+Access:
+- HTML Interface: http://your-server-ip:3000
+- API: http://your-server-ip:3000/api/tools
+- WebSocket: ws://your-server-ip:3000/ws
+
+### stdio Mode (for MCP Clients)
+
+Useful when launched by an MCP client (e.g., Claude Desktop, Cursor).
+
+```bash
+docker run --rm \
+    --name docx-mcp-stdio \
+    -v /host/path/templates:/templates:ro \
+    -v /host/path/output:/out \
+    -e DOCX_MCP_TEMPLATES_DIR=/templates \
+    -e DOCX_MCP_MAX_SIZE=104857600 \
+    -e DOCX_MCP_MAX_DOCS=30 \
+    --memory 1g \
+    --cpus 1.5 \
+    docx-mcp:full
+```
+
+In MCP client config, point "command" to "docker run" with these flags.

+## Monitoring
+
+```bash
+# View logs
+docker logs -f docx-mcp-http
+
+# Check resource usage
+docker stats docx-mcp-http
+
+# Verify security
+docker inspect --format='{{.HostConfig.ReadOnly}}' docx-mcp-http  # Should be true
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. Port already in use:
+   - Use a different port:
+     - -p 8080:8080 -e DOCX_MCP_HTTP_ADDRESS=0.0.0.0:8080
+
+2. Permission denied on temp directory:
+   - Ensure temp directory is writable:
+     - --tmpfs /tmp/docx-mcp:rw
+
+3. Out of memory:
+   - Increase memory:
+     - --memory 2g
+
+4. CORS issues in browser:
+   - CORS is enabled for all origins on LAN by default.
+   - For production, restrict to specific origins as needed.
+
+## API Key
+
+No API key is required. Security relies on:
+- OS-level access controls
+- Container isolation
+- Built-in command security (whitelist/blacklist)
+
+For LAN deployments, rely on:
+- Network-level access controls
+- Firewall rules
+- Application-level authentication at the bridge

+
+## Key Facts
+
+| Item | Value |
+|------|-------|
+| **Transport Method** | stdio (stdin/stdout) |
+| **Network Port** | Not required for local use |
+| **API Key** | Not required |
+| **Authentication** | OS-level + container security |
+
+---
+
+## Port Requirements
+
+### Local Deployment (Recommended)
+**No port required** - the server communicates via stdin/stdout directly.
+
+### Remote Deployment (Optional)
+If remote access is needed, wrap with a stdio-to-network bridge:
+
+| Bridge Type | Port | Protocol |
+|-------------|------|----------|
+| WebSocket | 8080 | ws:// |
+| TCP | 8080 | tcp:// |
+
+---
+
+## Quick Start
+
+### Build
+```bash
+# Minimal (recommended)
+docker build -f Dockerfile.sandboxed -t docx-mcp:sandboxed .
+
+# With LibreOffice (better PDF conversion)
+docker build -f Dockerfile.libreoffice -t docx-mcp:libreoffice .
+```
+
+### Run (Local)
+```bash
+docker run --rm \
+    --name docx-mcp \
+    --read-only \
+    --cap-drop ALL \
+    --tmpfs /tmp/docx-mcp \
+    --memory 512m \
+    docx-mcp:sandboxed

+## 🌐 Transport Modes
+
+The server supports two transport modes:
+
+- **stdio (default)**:
+  - Communicates over stdin/stdout.
+  - Ideal for MCP clients (Claude Desktop, Cursor, etc.).
+
+- **HTTP (for HTML/browser access over LAN)**:
+  - Provides:
+    - A web interface for browsing and using tools.
+    - A REST API for programmatic access.
+    - A WebSocket endpoint for real-time communication.
+
+To enable HTTP mode:
+
+```bash
+# Using command line
+./target/release/docx-mcp --http-mode --http-address 0.0.0.0:3000
+
+# Using environment variables
+export DOCX_MCP_HTTP=true
+export DOCX_MCP_HTTP_ADDRESS=0.0.0.0:3000
+./target/release/docx-mcp
+```
+
+Access:
+- HTML Interface: http://your-server-ip:3000
+- API: http://your-server-ip:3000/api/tools
+- WebSocket: ws://your-server-ip:3000/ws

+
+- **Templates directory**:
+  - Configurable via `--templates-dir` or `DOCX_MCP_TEMPLATES_DIR`.
+  - Intended to be mounted in Docker (e.g., `/templates`).
+- **Template tools**:
+  - `list_templates`: Lists all `.docx` templates available.
+  - `open_template`: Opens a template by name as a working document.
+  - `generate_from_template`: Generates a new document from a template with fill-in fields.
+- **Fill-in fields**:
+  - Use placeholders like `{{CLIENT_NAME}}` in your template.
+  - Provide field values as key-value pairs when calling `generate_from_template`.
+
+Example:
+
+```json
+{
+  "name": "generate_from_template",
