nexus-browser-mcp

An event-driven, deterministic browser automation MCP server built on Playwright. It drives browsers for LLMs via the Accessibility Tree, supporting navigation, clicking, typing, reading, and form filling. Key features include deterministic snapshots using MutationObserver, built-in HITL governance gates, multi-task isolation with independent BrowserContexts, self-healing capabilities for crashed tabs, and developer observability for console, errors, and network metadata.
