About Blueprint MCP

Blueprint MCP for Chrome connects AI assistants that speak the Model Context Protocol to your actual Chrome browser. Because it controls the browser you already use, you stay logged in to your sites, keep your extensions and present your normal browser fingerprint, which avoids many headless-browser and bot-detection problems.

Its main design choice is to avoid sending a full page snapshot after every action. Instead, the assistant clicks, types and navigates with CSS selectors and fetches page content only when needed, which keeps the model's context small and makes long multi-step workflows practical.

It is aimed at developers using Claude Code, Claude Desktop, Cursor or any MCP-compatible client who would otherwise reach for Playwright, Puppeteer or Selenium. The Chrome Web Store listing, published by 404 Software Labs SL, describes it as open source with zero telemetry.
