What is BRYG?

BRYG implements the Model Context Protocol (MCP) so any compatible client — such as Claude Code — can control a Chromium browser on your machine. It gives your AI assistant 43 tools covering perception, action, and observation, designed from daily QA work rather than demos.

Note: This repository hosts BRYG's public documentation and issue tracker. The product itself is distributed as a signed binary via the installer below.

Get started

BRYG is a licensed product — you need a key to activate it. It takes about a minute:

1. Get a license key — start your 14-day free trial at bryg.pages.dev. Your license key is emailed to you (billing, cancellation, and refunds are handled in the customer portal linked in that email).
2. Install — run the one-line installer for your OS (below).
3. Activate — the guided setup asks for your key during install, or run bryg activate <key> anytime.

Install

macOS

curl -fsSL https://bryg.pages.dev/install.sh | sh

Windows (PowerShell)

irm https://bryg.pages.dev/install.ps1 | iex

The installer downloads the right binary for your OS/architecture to ~/.bryg/bin/ (%USERPROFILE%\.bryg\bin\ on Windows), verifies its SHA-256 checksum, then runs a guided setup that registers BRYG with your MCP client(s), optionally installs OCR support, and activates your license key.

Why BRYG

• Sees pages like structure — accessibility-tree snapshots with stable element refs ([ref=N]); compact and reliable for AI to act on, with coordinate fallback.
• OCR & QR built in — reads text from canvas, images, and games (multi-strategy OCR, any tesseract language) and decodes QR codes on the page.
• Network capture — record everything, keyword-filtered, or failures-only. Sensitive headers and password/token-like fields are masked by default.
• Credentials stay local — secrets never enter AI conversations.
• Headful by design — a dedicated browser instance you can watch and take over at any time.
• Zero telemetry — runs entirely on your machine; the only network calls are license validation and an anonymous update check.

Perception — browser_snapshot · browser_read · browser_screenshot · browser_ocr · browser_qr Action — navigate · click · type · fill · scroll · press keys · drag · upload · select, and more Observation — network_start · network_stop · network_status
