Glossary

Each entry gives what the word means in Libretto, the label the admin shows for it (where there is one), and the guide page that explains it. Labels are quoted as the English admin shows them; the Italian glossary lists the Italian labels.

A #

• Access token. A named key, tied to one site and your role, that lets an agent act for you. It lasts 30 or 90 days and can be revoked at any time. You make it in the sidebar under People & access › Agents & MCP access (Persone e accessi › Agenti e accessi MCP), and see it once. See MCP.
• Activate (a version). Make an older published version the live site again. Your current draft is replaced by that version. Admin: Make live. See Publish and versions.
• Activity. The site's log of changes, one sentence per change, with Undo on each row. Super admins only. Admin: Activity, page title Activity log. See Hand a site to a client.
• Agent. A program, often an AI assistant, that edits a site through MCP or the CLI with the same operations as the editor. See Agents and API.

B #

• Batch. A list of up to 100 operations sent together. It succeeds or fails as a whole, and is recorded once in Activity. Not shown in the admin. See Batches.

• Blueprint. The starting point of a new site: its pages, components, menus and design system. The design system keeps the blueprint's values as the layer you can reset to. Admin: Blueprint. See Your first site.
• Brand client. A role that only creates brand assets for one site. It does not edit pages. Admin: Brand client. See Your workspace.
• Breakpoint. A screen width from which a style applies. Sites start with base, sm, md, lg and xl, mobile first. Admin: Breakpoints. See Layers and canvas.

• Detach. Turn an instance of a site component back into ordinary elements, so it no longer follows the component. Admin: Detach. See Site components.
• Domain. An address the site answers on, such as studio-rossi.it. One domain is the primary; the others redirect to it. Admin: Domains, Primary. See Domains.

M #
