This tool functions as a Model Context Protocol (MCP) server, bridging the gap between AI assistants like Claude Desktop and Cursor, and your Proton Drive files. It allows AI clients to perform a wide range of file management operations, including listing, reading, creating, writing, and deleting files and folders directly within your Proton Drive. By integrating with the local Proton Drive desktop app, it operates securely on your filesystem, preserving Proton's end-to-end encryption and requiring no external credentials, thereby enhancing AI-driven productivity for cloud-stored documents.
