# Agent Browser

> Gives Claude agents a headless browser. Use when you need to fetch JS-rendered pages, interact with UI elements before reading content, or observe network traffic. Invoke the browser_session tool to navigate, click, type, read DOM, take screenshots, and capture network requests — all in one isolated call.

## About

## agent-browser

This skill exposes a headless Chromium browser as the `browser_session` MCP tool.

### When to use

- Fetching content from JS-rendered pages (SPAs, React/Vue apps)
- Interacting with a page before reading its content (login forms, search boxes, navigation)
- Observing API calls a page makes (XHR/fetch requests, WebSocket handshakes)
- Taking visual screenshots of a page state

### Key properties

- **Fully isolated**: Each call gets a fresh browser context. No cookies, localStorage, or session state carries over between calls.
- **Structured output**: Returns `title`, `finalUrl`, `dom`, `screenshot` (base64 PNG), and `networkLog` in a single JSON response.
- **Declarative steps**: Provide an ordered `steps` array — no arbitrary code execution.

### Example usage

```json
{
  "url": "https://example.com",
  "steps": [
    { "type": "wait_for", "selector": "#main-content" },
    { "type": "read_dom", "selector": "article" },
    { "type": "screenshot" }
  ],
  "captureResponseBodies": false
}
```

### Step types

| Type | Required | Optional | Description |
|------|----------|----------|-------------|
| `navigate` | `url` | — | Navigate to a new URL |
| `click` | `selector` | — | Click an element |
| `type` | `selector`, `text` | — | Type text into a field |
| `wait_for` | `selector` | `timeout` (ms) | Wait for element to appear |
| `wait_ms` | `ms` | — | Fixed delay |
| `read_dom` | — | `selector` | Extract text (defaults to body) |
| `screenshot` | — | — | Capture viewport as base64 PNG |
