SEAL Box: a browser inbox for files from your AI agent

[MariaLi]

I'm Maria, working on SEAL.

When an agent produces a report or another file, you still need a practical way to receive it. SEAL Box provides a browser inbox for agent-generated files. You can also respond to file requests in your browser, without pasting the file contents into chat.

SEAL's web transfer encrypts files in the browser before upload. The basic sharing flow does not require an account or email. You can set expiry and password protection, use single-use access, and revoke future access. Revocation does not remove copies someone has already downloaded.

For agent workflows, we provide MCP and CLI tools. Our published Claude Code skill guides an agent in using those tools for delivery, inboxes, requests and revocation. The skill is guidance, not a separate transfer service.

Two practical details: save your Box recovery key privately, and review your agent host's permissions. A file path is not a security boundary if the agent can read that file.

If you work with agent-generated reports, what is missing from your current delivery workflow? I'd value feedback on the handoff and inbox experience.

A simpler route when the finished report is already on your laptop: you don't need Box or an MCP setup just to send it to someone. I work on SEAL; here's the ordinary browser flow.

1. Open https://seal.net and choose Tap to send.
2. Select your PDF or ZIP, choose how long the link should work, and create the transfer.
3. Send the recipient link in your existing email or chat. Neither person needs a SEAL account. Keep the separate management link private.

The free option supports up to 1 GB per transfer and up to 7 days. If several colleagues need the file, don't choose single-use access. For a password-protected handoff, send the password through a separate channel.

This is temporary delivery, not a permanent archive. Expiry or revocation stops future access through the link; it cannot remove a copy someone has already downloaded.
