Proton Drive CLI MCP

Typed Proton Drive tools that shell out to Proton's official CLI, so sign-in and encryption stay with Proton.

LABSCO SUMMARY

Destructive tools stop and ask.

Anything that removes data or changes the account — trash, delete, empty trash, logout, removing a share — refuses to run unless the call carries confirm: true, which turns an ambiguous instruction into a second explicit step rather than a lost file. The other design choice worth knowing about is that folder listings and job output come back bounded, with counts and a truncated flag, so pointing an assistant at a large Drive does not dump the whole tree into context.

What it is

A stdio server that exposes Proton Drive as schema-checked tools instead of prompt-written command lines. Every operation runs through Proton's official proton-drive CLI, so authentication, session storage and the encrypted Drive behaviour are Proton's code, not a reimplementation. It is an independent wrapper, not a Proton product.

What you get

  • proton_drive_list, proton_drive_info and proton_drive_create_folder browse and build the tree, with list output bounded and paged
  • proton_drive_upload and proton_drive_download move files, with proton_drive_upload_async and proton_drive_download_async returning a job id instead of blocking
  • proton_drive_job_status and proton_drive_job_cancel follow or stop a background job
  • proton_drive_read_text and proton_drive_write_text read and write small UTF-8 files directly, rejecting binary or oversized content
  • proton_drive_rename, proton_drive_copy, proton_drive_move, proton_drive_trash, proton_drive_restore and proton_drive_delete reorganise and remove
  • proton_drive_sharing_invite, proton_drive_sharing_status, proton_drive_sharing_set_url and proton_drive_sharing_remove handle people and public links
  • proton_drive_diagnose and proton_drive_setup report CLI discovery, version, PATH and auth state, and install what is missing

Requirements

Node.js 22+ and the official Proton Drive CLI. Run it as npx -y @borealstack/proton-drive-cli-mcp (package @borealstack/proton-drive-cli-mcp, version 0.1.2) over stdio. If the CLI is missing the server downloads the current official build for your OS and CPU and verifies Proton's SHA-512 checksum before using it; set PROTON_DRIVE_CLI_PATH to point at your own copy, or PROTON_DRIVE_CLI_AUTO_INSTALL=0 to switch that off. Sign-in happens in the browser through the CLI and the session lands in the OS secret store — this server never sees or stores Proton credentials.

Setup effort

One command — npx -y @borealstack/proton-drive-cli-mcp
