Documentation Overview
spa-reader-mcp
MCP server that renders JavaScript SPA pages and extracts Markdown via headless Chromium.
Traditional scrapers fail on SPAs because content is rendered client-side. This tool launches Playwright, waits for JS to finish, then extracts clean Markdown using Readability + Turndown.
