An MCP tool that lets AI agents send files end-to-end encrypted. Files are encrypted on your computer before upload, deleted after one download, and the model
What it is
VitalSend™ is a one-time encrypted file transfer service for AI agents integrated with Claude, Cursor and Claude Desktop. Files are encrypted with XChaCha20-Poly1305 in the sender's browser before upload. Each transfer allows exactly one complete download, after which the file is automatically destroyed or after 7 days if undownloaded. The encryption key resides in the URL fragment that servers never see, so VitalSend™ stores only unreadable ciphertext. Recipients need the password sent separately to decrypt. Transfers up to 1 TB are supported. The service operates from Gothenburg, Sweden under strict irreversibility guarantees: no transfer history is kept, files cannot be recovered, and continued existence is prevented by design.

Quick answers
- How does VitalSend™ work?
- Files are encrypted on your device before upload and can only be decrypted by the recipient. Each transfer allows exactly one successful download. After download, or after 7 days if nobody downloads it, the file is automatically destroyed. VitalSend™ is designed for secure handover, not long-term storage or collaboration.
- Can VitalSend™ read my files?
- No. Files are encrypted before upload and stored encrypted. Only the recipient can decrypt the file contents. VitalSend™ cannot access or read uploaded files. The encryption code that runs in your browser is open source.
- What happens if the link leaks?
- After one successful download, the file is destroyed and the link becomes useless. If password protection is enabled, the correct password is required before download. Repeated incorrect attempts destroy the transfer.
- How do credits work?
- All plans include monthly transfer credits. Without a plan, an account with a verified email gets 3 free credits each month. Transfers consume credits based on file size: up to 1 GB uses 1 credit, up to 10 GB uses 2 credits, up to 100 GB uses 4 credits, up to 1 TB uses 8 credits. Additional credits can be purchased when needed.
- Does VitalSend™ support large file transfers?
- Yes. VitalSend™ supports transfers up to 1 TB on every plan. Larger files use more credits. Large uploads can be resumed if they are interrupted.
