File viewer and discussions

A new document opens in the Fermium viewer when you share its link. The viewer frames the file under a Fermium header and adds a discussion. Documents published before 3 November 2026 keep the setting they already had.

What readers see

• The file itself, shown from the content origin. See two origins.
• Comment threads with replies. A thread is pinned to the version it was written on.
• People with comment access can resolve threads. Comments are part of the paid plans; see plans and limits.

Choose File only

In the document's inspector, choose File only instead of Fermium viewer when the link should serve the file with no header, for example for an embed or a download. Closing comments keeps the feedback already written. Link choice never changes who can open the document.

Forms and Agent files keep their own screens, so this setting does not apply to them. The url of a document still serves the file. Only share_url follows the presentation you chose.

From an agent

Call get_file_presentation to read the current setting and revision. Call set_file_presentation with that revision to change it. Use list_comments, add_comment and resolve_comment for the discussion. The steps are in the MCP reference and in usage_guide.
