Playwright

About

This tool acts as a Model Context Protocol (MCP) server, offering browser automation capabilities powered by Playwright. It facilitates Large Language Models (LLMs) in interacting with web pages by providing structured accessibility snapshots, thereby eliminating the need for visual input like screenshots or specialized vision models. The server is designed to be fast, lightweight, and LLM-friendly, operating purely on structured data from Playwright's accessibility tree to ensure deterministic tool application and avoid ambiguities often associated with pixel-based or screenshot-driven approaches.

Key Features

• Fast and lightweight browser automation using Playwright's accessibility tree
• LLM-friendly, requiring no vision models and operating on structured data
• Deterministic web interaction, avoiding ambiguity of screenshot-based methods
• Connects to existing browser instances via an extension
• Supports persistent user profiles or isolated sessions for flexibility
• 0 GitHub stars

Use Cases

• Integrating browser automation into various AI development environments (MCP clients)
• Automating web tasks for AI agents and LLMs
• Enabling LLMs to browse and extract information from web pages
