概览

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.

Key features of MCP Web Snapshot

Fast and lightweight using Playwright’s accessibility tree
LLM-optimized structured data output
Comprehensive network and console message monitoring
Unique element references for interactive elements

常见问题

What are the system requirements?

Python 3.11 or newer and a compatible MCP client (e.g., VS Code, Cursor, Claude Desktop).

How do I install Playwright browsers?

Run `uv run playwright install` after setting up the project dependencies.

Can I customize the viewport size or timeout?

Yes, edit the `CONFIG` dictionary in `src/tools/snapshot_url.py` to adjust viewport, user agent, and timeout settings.

What happens if I provide an invalid URL?

The server returns a helpful error message for malformed URLs.

How is this different from the interactive Playwright MCP?

MCP Web Snapshot focuses on one-shot, structured snapshots with network and console monitoring, while Playwright MCP offers interactive browser control.
