✨ Features

• ⚡ Lightning Fast: Leverages WizTree's MFT (Master File Table) reading to scan drives in seconds.

• 🧠 AI-Powered Workflows: Ask your AI: "What's eating up space on my C: drive?" or "Analyze my Downloads folder."

• 🛡️ Built-in Guardrails: Comes with a comprehensive /skills directory to teach your AI strict deletion policies and safe handling of files.

• 💻 Developer Focused: Perfect for finding hidden node_modules, stray __pycache__ folders, or giant dangling Docker images.

🧠 AI Agent Skills

Unlike basic MCP servers that just dump raw data, this repository includes a dedicated /skills directory and a SYSTEM_PROMPT.md. These Markdown files teach your AI client how to use the tools effectively and safely.

Available skills include:

• 🛡️ Deletion Policy: Enforces a strict multi-step workflow before any files are deleted.

• 🗑️ Safe Delete: Defines exactly what is safe to delete (e.g., caches) and what should never be touched (e.g., system files).

• 👨‍💻 Developer Cleanup: Gives the AI deep knowledge of where dev tools (Docker, npm, pip) hide their massive cache files.

⚙️ Configuration

Add the server to your MCP client configuration (e.g., mcp_config.json for Antigravity, or claude_desktop_config.json for Claude):

{
  "mcpServers": {
    "wiztree": {
      "command": "C:\\path\\to\\Wiztree-Mcp\\.venv\\Scripts\\python.exe",
      "args": [
        "C:\\path\\to\\Wiztree-Mcp\\server.py"
      ]
    }
  }

⚠️ Note: Replace C:\\path\\to\\ with the exact absolute path to your cloned directory.

🤖 Example Prompts

Once connected, try asking your AI:

• 💬 "Can you find the 15 largest files on my C: drive?"

• 💬 "My SSD is full. Find the largest folders in my user profile, skipping my personal photos."

• 💬 "Do a developer cleanup on my machine to free up at least 20 GB."
