This is a Chromium-based browser built for persistent agent workflows with visible human supervision. It exposes MCP tools for navigation, form interaction, page reading, bookmarks with structured metadata (intent, expectedContent, keyFields, agentHints), checkpoint snapshots, and action undo. The browser stays open across sessions, renders pages normally so you can watch what the agent does, and includes a sidebar for approval gates and runtime controls. Reach for this when you want your agent to maintain browser state across long runs, build up a structured bookmark library, or work through multi-step workflows where a human needs to audit and redirect without losing context.
