Blueprint MCP
Browser automation via MCP for Chrome and Firefox
Ads
Overview
> Control your real browser with AI through the Model Context Protocol An MCP (Model Context Protocol) server that lets AI assistants control your actual browser (Chrome, Firefox, or Opera) through a browser extension. Unlike headless automation tools, this uses your real browser profile with all your logged-in sessions, cookies, and extensions intact. Perfect for: AI agents that need to interact with sites where you're already logged in, or that need to avoid bot detection. Chrome / Edge / Opera - Chrome Web Store (works for all Chromium browsers) - Manual: Download from Releases, then load unpacked at chrome://extensions/ (Chrome), edge://extensions/ (Edge), or opera://extensions/ (Opera)

- Navigate and read pages in your real browser
Ask the assistant to go to a URL with `browser_navigate` and extract the accessible content via `browser_snapshot` or `browser_extract_content`.
- Interact with page elements
Use `browser_interact` or `browser_click`, `browser_type`, `browser_fill_form`, and `browser_select_option` to click, type, fill forms, and choose dropdown options.
- Monitor network activity
Inspect, filter, and replay captured requests with `browser_network_requests`, including JSONPath filtering on response bodies.
- Capture visual state
Take a screenshot of the current page with `browser_take_screenshot` or save it as a PDF using `browser_pdf_save`.
- Manage tabs and windows
List, create, attach to, or close tabs via `browser_tabs`, and resize or minimize the window with `browser_window`.
- Run custom JavaScript and handle dialogs
Execute arbitrary scripts in the page using `browser_evaluate` and manage alerts, confirms, or prompts with `browser_handle_dialog`.
