MCP Playwright

What is mcp-playwright

mcp-playwright is a Model Context Protocol (MCP) server developed by executeautomation. It provides powerful browser automation capabilities using the Playwright framework. This server allows Large Language Models (LLMs) to interact with web pages directly, enabling functionalities such as taking screenshots and executing JavaScript in a real browser environment. By leveraging mcp-playwright, AI systems can perform complex web-based tasks in a secure and efficient manner.

MCP, developed as an open-source protocol by Anthropic, provides a universal standard for AI systems to connect securely with various data sources and tools. Using MCP, AI assistants can access real-time information, tools, and external data sources through a robust client-server architecture.
