Overview

What is MCP Web Snapshot?

MCP Web Snapshot is a Model Context Protocol server that uses Playwright to capture comprehensive website snapshots, including accessibility trees, network requests, and console messages, designed for LLM-based analysis. It is built for developers using MCP clients such as VS Code, Cursor, Windsurf, or Claude Desktop.

How to use MCP Web Snapshot?

Install dependencies with uv sync and Playwright browsers with uv run playwright install, then configure the server in your MCP client using a JSON object with command: "uv" and args: ["--directory", "/path/to/mcp-web-snapshot", "run", "python", "src/server.py"]. After setup, invoke the website_snapshot tool with a valid URL.
