- ✏️ **Create and write files** to Proton Drive
- 🗑️ **Delete files and folders**
- 📂 **Create new folders**
- 🔄 **Cross-platform support** (Windows, macOS, Linux)
- 🔒 **Secure** - Works through local filesystem, no credentials needed
- 🚀 **Easy to install** - Just npm install and configure

## 📋 Prerequisites

- Node.js 16 or higher
- Proton Drive desktop app installed and synced
- Claude Desktop, Cursor, or any MCP-compatible client

## 🚀 Quick Start

### 1. Install from npm (Recommended)

```bash
npm install -g proton-drive-mcp
```

### 2. Or install from source

```bash
git clone https://github.com/anyrxo/proton-drive-mcp.git
cd proton-drive-mcp
npm install
npm run build
```

## ⚙️ Configuration

### Finding your Proton Drive path

The MCP will try to auto-detect your Proton Drive location, but you can also set it manually:

- **macOS**: `~/Library/CloudStorage/ProtonDrive-[email]-folder`
- **Windows**: `C:\Users\[username]\Proton Drive`
- **Linux**: `~/ProtonDrive`

### Claude Desktop

Add to your Claude Desktop config:

**macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
**Windows**: `%APPDATA%\Claude\claude_desktop_config.json`

```json
{
  "mcpServers": {
    "proton-drive": {
      "command": "node",
      "args": ["path/to/proton-drive-mcp/dist/index.js"]
    }
  }
}
```

### Cursor

Add to your Cursor settings:

```json
{
  "mcp.servers": {
    "proton-drive": {
      "command": "node",
      "args": ["path/to/proton-drive-mcp/dist/index.js"]
    }
  }
}
```

### Custom Proton Drive Path

If your Proton Drive is in a non-standard location:

```json
{
  "mcpServers": {
    "proton-drive": {
      "command": "node",
      "args": ["path/to/proton-drive-mcp/dist/index.js"],
      "env": {
        "PROTON_DRIVE_PATH": "/custom/path/to/ProtonDrive"
      }
    }
  }
}
```

## 🎯 Usage Examples

Once configured, you can ask your AI assistant:

- "List all files in my Proton Drive"
- "Create a new file called notes.txt with some content"
- "Read the contents of Documents/report.pdf"
- "Create a new folder called Projects"
- "Delete the file old-notes.txt"

## 🛠️ Available Tools

The MCP provides these tools:

| Tool | Description |
|------|-------------|
| `check_mount` | Verify Proton Drive is accessible |
| `list_files` | List contents of a directory |
| `read_file` | Read file contents |
| `write_file` | Create or overwrite files |
| `delete_file` | Remove files or folders |
| `create_folder` | Create new directories |

## 🧪 Testing

Test if the MCP is working:

```bash
# Check if Proton Drive is detected
npm run test:connection

# Run all tests
npm test
```

## 🔧 Troubleshooting

### Proton Drive not found

1. Make sure Proton Drive desktop app is running
2. Check if your files are synced
3. Set `PROTON_DRIVE_PATH` environment variable manually

### Permission errors

- Ensure the MCP has read/write access to your Proton Drive folder
- On macOS, you may need to grant permissions in System Preferences

1. Restart your AI client after configuration
2. Check the logs for any error messages
3. Verify the path to the MCP is correct
