Nova vs mcp-chrome

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.; mcp-chrome: Chrome MCP Server transforms your Chrome browser into an AI-controlled automation tool by exposing its functionality via the Model Context Protocol. It allows LLMs and AI assistants like Claude to interact with your browser, leveraging your existing user habits and login states for complex tasks.
