# Agent Browser

A fast, native Rust CLI that gives AI agents full browser control via Chrome DevTools Protocol (CDP). Agents navigate pages, read accessibility-tree snapshots with compact element refs, click, fill, screenshot, manage tabs, handle auth, and run multi-step web workflows — all without Playwright or Node.js.

## Install

```bash
curl -fsSL https://agent-browser.sh | bash
```

Or via npm:

```bash
npx agent-browser@latest
```

## Load the skill prompt at runtime

```bash
agent-browser skills get core
```

This fetches the up-to-date workflow prompt directly from the source — avoids stale context.

## Key commands

```bash
# Open a page and get an accessibility snapshot
agent-browser navigate https://example.com

# Click an element by ref ID (from a prior snapshot)
agent-browser click @e3

# Fill a form field
agent-browser fill @e7 "hello@example.com"

# Take a screenshot
agent-browser screenshot

# Natural language control via AI Gateway
agent-browser chat "go to zynkr.ai and find the pricing section"
```

## Cloud providers

Supports local Chrome/Chromium, Browserbase, Browserless, Browser Use, Kernel, and AWS Bedrock AgentCore. Configure via environment variables or `~/.agent-browser/config.toml`.
