AI consent flow simplified to three options

When AI agents need to access tools or resources, users see a consent prompt. Previously, the n8n instance UI offered five choices including permanent "Always allow" and "Always deny" options that would remember decisions across sessions.

The new flow presents just three options: "Deny once," "Allow once," and "Allow for session." The default action is now "Allow" instead of "Allow for session," reducing the chance of accidentally granting prolonged access. "Allow for session" remains available but moved to a dropdown.

The CLI tool continues to show all five options since it's a direct human interface where users can intentionally make persistent choices. The distinction is intentional — instance UIs see the simplified flow while CLI retains the full set.

This change targets decision fatigue in AI agent workflows, particularly when agents repeatedly request access to the same resources. By removing permanent decisions from the UI, users aren't burdened with remembering which resources they previously allowed or denied forever.
