YAFL — Yet Another File Layer (MCP server + CLI) tools 7
upload_fileEncrypts and uploads exactly the file or directory at the given local `path` (absolute, or relative to the current working directory). A directory is zipped client-side into a single archive before upload. Reads only that one path – never scans unrelated files or directories. Returns a shareable link (24h expiry, 100MB cap) with the decryption key embedded in the URL fragment; the key is never sent to the API. Optionally make the link one-time (burned after the first download) or password-protected.get_statusChecks whether the YAFL share link at the given `url` is still live — live, expired, or not found — without downloading or decrypting anything. Returns liveness, size, and expiry only. Does not read the decryption key even if present in the URL fragment, and never fetches any file bytes.download_fileDownloads and decrypts exactly the one file referenced by the given YAFL share `url`, writing it only into `destDir` (default: the current working directory) — never anywhere else. Requires the decryption key embedded in the URL fragment; the key is used only locally to decrypt and is never sent to the API. No YAFL API key is required for retrieval — anyone holding the link can download it; only uploading or managing files requires a key. Optionally pass a `password` for password-protected links.list_filesLists the caller's OWN YAFL transfers only — metadata only (id, size, status, expiry, and a download path). Never returns file contents, never a decrypted name, and never another account's files. Optionally cap the number of results with `limit`.delete_filePermanently deletes ONE of the caller's own YAFL transfers, identified by `id` (a bare transfer id or a full share URL — the fragment/key, if present, is never read). This cannot be undone: the R2 object is purged and the transfer record is removed. Destructive action.email_linkEmails this YAFL share link to a recipient. The link carries the decryption key in its fragment – anyone with access to that inbox can open the file. Requires a verified account.loginStarts a device-code login for an MCP agent that has no shell. Returns a verification URL and a short user code for the human to open and approve in a browser; approving is a one-time email-link sign-in that proves the human controls the account. This tool does NOT open a browser itself - relay the returned URL and code to the human. Once approved, the minted API key is stored locally and subsequent tool calls in this session authenticate automatically, with no further action needed.
