Connects Claude to your real Chrome/Firefox—not headless. Keeps all your logged-in sessions, bypasses bot detection, uses CSS selectors instead of context-killing snapshots. Claude sees a button, clicks button:has-text('Submit'), verifies results. Perfect for authenticated automation, frontend debugging, testing behind 2FA. Includes 20+ tools: screenshots, network capture, console logs, form filling. Free, open source (Apache 2.0), runs locally with zero telemetry or cloud calls.

Hi Product Hunt! 👋

I built Blueprint MCP after getting frustrated with existing browser automation MCPs.

The problem: They spawn headless browsers (bot detection!), require constant re-auth,
and send massive snapshots that kill your context window.

Demo: 3-minute comparison on Amazon - Browser MCP fails, Blueprint MCP works:

Testimonial:

"This is really nice. It works really well for exploratory and debugging stuff."

Blueprint MCP is different:
✓ Controls YOUR actual browser (Chrome/Firefox)
✓ Uses your logged-in sessions
✓ CSS selectors instead of snapshots
✓ Can verify its own work
✓ Free, open source, runs locally

Perfect for:
- Automating behind login/2FA
- Testing with real sessions
- Debugging frontend issues
- Web scraping without detection

Happy to answer questions!

Blueprint MCP is working flawlessly. Glad someone figured it out with consistency.
