Playwright MCP Server

This Actor wraps the playwright-mcp project to provide a serverless Playwright browser in the cloud. A Model Context Protocol (MCP) server that provides browser automation capabilities using Playwright. This server enables LLMs to interact with web pages through structured accessibility snapshots, bypassing the need for screenshots or visually tuned models.
