+# DGX Spark MCP Server Playbook
+
+This playbook installs and configures the **DGX Spark MCP Server**, a tool that provides hardware-aware Apache Spark optimization for NVIDIA DGX systems via the Model Context Protocol (MCP).
+
+## Overview
+
+The DGX Spark MCP Server enables MCP clients (like Claude Desktop or Claude Code) to:
+*   **Detect Hardware**: Automatically read DGX GPU topology, memory, and CPU specs.
+*   **Optimize Spark**: Generate tuned Spark configurations (`spark-submit` args) based on detected hardware and workload type (ETL, ML Training, Inference).
+*   **Monitor**: Check real-time GPU availability before submitting jobs.
+
+## Prerequisites
+
+*   **NVIDIA DGX System** (or compatible GPU server)
+*   **NVIDIA Drivers** installed (`nvidia-smi` available)
+*   **Node.js 18+**
+*   **Root access** (for systemd service installation)
+
+## Directory Structure
+
+```
+.
+├── config/
+│   └── default.json       # Default configuration
+├── deploy/
+│   └── dgx-spark-mcp.service # Systemd service file
+└── scripts/
+    └── install.sh         # Automated installer
+```
+
+## Installation
+
+1.  **Run the installer**:
+    ```bash
+    sudo ./scripts/install.sh
+    ```
+    This script will:
+    *   Install `dgx-spark-mcp` globally via `npm`.
+    *   Create a dedicated system user (`dgx`).
+    *   Setup logging directory `/var/log/dgx-spark-mcp`.
+    *   Install and start the systemd service.
+
+2.  **Verify Installation**:
+    ```bash
+    systemctl status dgx-spark-mcp
+    ```
+
+## Configuration
+
+The configuration file is located at `/etc/dgx-spark-mcp/config.json`.
+
+### Key Settings
+
+*   **`mcp.transport`**: `stdio` (default) or `sse`.
+*   **`hardware.enableGpuMonitoring`**: Set to `true` to enable real-time `nvidia-smi` queries.
+*   **`logging.level`**: `info` or `debug`.
+
+## Usage with Claude Desktop
+
+Add the following to your `claude_desktop_config.json`:
+
+```json
+{
+  "mcpServers": {
+    "dgx-spark": {
+      "command": "dgx-spark-mcp"
+    }
+  }
+}
+```
+
+## Troubleshooting
+
+**Service fails to start?**
+Check logs:
+```bash
+journalctl -u dgx-spark-mcp -f
+```
+
+**Permission denied?**
+Ensure the `dgx` user has permissions to access `nvidia-smi`. You may need to add the user to the `video` group:
+```bash
+usermod -a -G video dgx
+```
