What data it sees

Do you need an account

No: the server works without sign-in

Private, EU-hosted file transfer for AI assistants. Ask what arrived and who downloaded it, share files as expiring links, and email them to people, with every send confirmed by you.

  • Read: transfers, download receipts, collections, folders, guests, contacts.
  • Share: turn content into an expiring link without emailing anyone.
  • Send: email a transfer, only with a separately granted permission and after you confirm the recipients.

Never deletes, revokes or invites. Everything it returns is marked as untrusted data. Sign in once with OAuth (no API key); works on the free plan. Hosted in Germany.

get_accountAnswers: how much storage am I using? how much is left? what plan am I on? what can this connection do? Returns the workspace, its plan and quota, and the key's permissions.
list_transfersAnswers: what have I sent recently? what is expiring soon? which deliveries has nobody picked up? who did I send that to? Returns recent transfers with size, recipients, download count, expiry date and share link.
get_transferAnswers: what is in this transfer? was it delivered? has a specific recipient opened it? is it safe to share? Returns the files with their malware-scan verdicts, plus per-recipient delivery and download status for one transfer id.
get_transfer_downloadsAnswers: did the client download it? when? how many times? Returns download events with timestamps and per-recipient status. One visit can fetch several files: events that share a sessionId belong to the same visit.
list_collectionsAnswers: what collections do I have? which are empty? how big is each one? Returns collections with file counts, sizes and when each was last touched. A collection is a durable space clients are invited into, as opposed to a one-off transfer. Never includes the vault, which is unreadable to this server by design.
get_collectionAnswers: what is the link for this collection? how much is in it? when does it expire? Returns one collection with its secret share link, file count, total size and expiry.
list_collection_filesAnswers: what files are in this collection? what is in this folder? are the raws uploaded yet? Returns filenames, sizes and types. Omit folderId for every file; pass "root" for the top level only, or a folder id. Filenames only — never file contents.
list_foldersAnswers: how is this collection organised? what folders exist? Returns the folder tree. Ordered by depth, then path (not a pre-order traversal). Each folder carries its parentId and its full path.
list_guestsAnswers: who has access to this collection? who did I invite? has someone accepted? Returns the invited guests and their status. Guests are not workspace members — they can view and download this one collection and nothing else.
list_contactsAnswers: what is this client's email address? who do I have saved? Returns the workspace address book. A contact grants no access on its own — it is a convenience, not a permission.
create_transferPrepare a draft transfer for files the user will upload themselves, and return its id. It uploads no files and emails nobody: the user uploads the files and sends the transfer themselves, in the browser or with the Yungle CLI.
create_share_linkUpload one or more small files you have the content of (text, or base64 for binary) as a Yungle transfer and return its link. Nobody is emailed: the link is returned to you, and the user decides where it goes. Up to 25 MB in total. Links expire (7 days on the free plan).
