agent-browser is a native Rust CLI tool designed for browser automation specifically tailored for AI agent workflows. It employs a client-daemon architecture where the Rust daemon manages persistent browser sessions via Chrome DevTools Protocol (CDP) or WebDriver, while the CLI provides command-line interface for controlling browsers. The system includes a Next.js dashboard for manual session monitoring and control, an MCP server for standardized AI agent tool integration, and a skills system for sharing and discovering agent workflows. Key features include snapshot-ref-act workflows for interactive element manipulation, secure credential vaults, provider integrations (Browserbase, Browserless, etc.), AI chat panels via Vercel AI Gateway, and extensive observability capabilities. The project emphasizes security through content boundaries, domain allowlists, and action policies, making it suitable for production AI agent deployments.
