Nova vs playwright-mcp

Nova: Nova is a Rust-native implementation of "computer use" capability for LLM agents, enabling AX-first control over macOS and Windows through semantic UI interactions, screenshots, OCR, and various input methods. It acts as a Model Context Protocol server, offering robust and direct system-level automation without relying on Python/JS stacks.; playwright-mcp: Playwright MCP is a server that leverages Playwright's browser automation capabilities to enable Large Language Models (LLMs) to interact with web pages. It utilizes structured accessibility snapshots, allowing LLMs to process web content without relying on visual input or traditional screenshots.

When to choose:
  • You want an agent to drive a real browser through structured accessibility snapshots instead of screenshots, so no vision model is needed.
  • You need Firefox, WebKit or Edge as well as Chrome: the README's --browser option lists chrome, firefox, webkit and msedge.
  • You want to test or script flows with isolated in-memory profiles (--isolated), device emulation (--device) or saved Playwright traces (--save-trace).
When to skip:
  • Your main goal is debugging or performance analysis of a page; Chrome DevTools MCP exposes performance traces and network inspection as dedicated tools.
  • You need proxies, CAPTCHA handling or large-scale scraping of protected sites; that is outside what the README claims for this server.
  • You want to treat it as a sandbox: the project says its origin allow and block lists are not a security boundary.
