How it works

Attach a file in the side panel. Browsentic reads it once, at attach time, and keeps notes about what it is.

From then on the agent sees those notes — never your filesystem — plus two tools:


`page_listFiles`	Re-read the list, with each file's summary
`page_attachFile`	Put one into an `<input type="file">` on the page

So the agent knows what it is uploading without being able to open anything you did not hand it.

Uploading is gated

page_attachFile is a confirm by default under the file-upload rule: putting a file into a page hands it to whoever runs that site.

For an MCP client, which cannot answer a prompt, it is refused outright.
