Proton Drive MCP

A Model Context Protocol (MCP) server that enables AI assistants like Claude Desktop, Cursor, and other MCP-compatible clients to interact with your Proton Drive files.

✨ Features

  • 📁 List files and folders in your Proton Drive

  • 📄 Read file contents directly

  • ✏️ 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)

npm install -g proton-drive-mcp

2. Or install from source

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

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

Cursor

Add to your Cursor settings:

{ "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:

{ "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"
