|

### Capturing XHR/Fetch Requests
|
||||
|
||||
Many SPAs load data through background API calls (XHR/fetch). You can capture these requests by passing a regex URL pattern to `capture_xhr` at the session level:
|
||||
|
||||
```python
|
||||
from scrapling.fetchers import DynamicSession
|
||||

print(xhr.body) # Raw response body as bytes
|

```
|

Each item in `captured_xhr` is a full `Response` object with the same properties (`.url`, `.status`, `.headers`, `.body`, etc.). When `capture_xhr` is not set or is `None`, `captured_xhr` is an empty list.

The Scrapling MCP Server provides nine powerful tools for web scraping:
|
||||
|
||||
### 🚀 Basic HTTP Scraping
|
||||
- **`get`**: Fast HTTP requests with browser fingerprint impersonation, generating real browser headers matching the TLS version, HTTP/3, and more!
|
||||
- **`bulk_get`**: An async version of the above tool that allows scraping of multiple URLs at the same time!
|
||||
|
||||
### 🌐 Dynamic Content Scraping

### 🌐 Dynamic Content Scraping
|
||||
- **`fetch`**: Rapidly fetch dynamic content with Chromium/Chrome browser with complete control over the request/browser, and more!
|
||||
- **`bulk_fetch`**: An async version of the above tool that allows scraping of multiple URLs in different browser tabs at the same time!
|
||||
|
||||
### 🔒 Stealth Scraping
|
||||
- **`stealthy_fetch`**: Uses our Stealthy browser to bypass Cloudflare Turnstile/Interstitial and other anti-bot systems with complete control over the request/browser!

- **`bulk_stealthy_fetch`**: An async version of the above tool that allows stealth scraping of multiple URLs in different browser tabs at the same time!
|
||||
|
||||
### 🔌 Session Management
|
||||
- **`open_session`**: Create a persistent browser session (dynamic or stealthy) that stays open across multiple fetch calls, avoiding the overhead of launching a new browser each time.
|
||||
- **`close_session`**: Close a persistent browser session and free its resources.
|
||||
- **`list_sessions`**: List all active browser sessions with their details.
|
||||
|
||||
### Key Capabilities
|
||||
- **Smart Content Extraction**: Convert web pages/elements to Markdown, HTML, or extract a clean version of the text content
|
||||
- **CSS Selector Support**: Use the Scrapling engine to target specific elements with precision before handing the content to the AI

|
||||
- **Parallel Processing**: Scrape multiple URLs concurrently for efficiency
|
||||
- **Session Persistence**: Reuse browser sessions across multiple requests for better performance
|
||||
- **Prompt Injection Protection**: Automatic sanitization of hidden content (CSS-hidden elements, aria-hidden, zero-width characters, HTML comments, template tags) that could be used for prompt injection attacks

7. **Using Persistent Sessions**
|
||||
|
||||
When scraping multiple pages from the same site, use a persistent browser session to avoid the overhead of launching a new browser for each request:
|
||||
```
|
||||
Open a stealthy browser session with 5 pages maximum pool, then use it to scrape the main details in bulk from the first 5 product pages on https://shop.example.com. Close the session when you're done.
|
||||
```
|
||||
Claude will use `open_session` to create a persistent browser, pass the `session_id` to `bulk_stealthy_fetch` call while opening all pages at the same time, and then call `close_session` at the end. This is significantly faster than launching a new browser for each page.
|
||||
|
||||
!!! danger
|
||||
|
||||
When using persistent sessions, always remember to close the session after you finish or it will stay open!
|
||||
|
||||
|
||||
8. **Using Persistent Session on a long flow**
|
||||
|
||||
Another long test example that makes Clause think:
|
||||
|
||||
```
|
||||
Use Scrapling MCP to do the following in this order:
|
||||
|
||||
1. Open a stealthy browser session with headless mode off.
|
||||
2. Go to this page and collect the number of stars: https://github.com/D4Vinci/Scrapling
|
||||
3. From the README, get the URL that shows the number of downloads and go to it.
|
||||
4. Get the number of downloads and the top 3 countries from the graph.
|
||||
5. Prepare a report with the results.
|
||||
6. Close the browser.
|
||||
```
|
||||
|
||||
And so on, you get the idea. Your creativity is the key here.

## Best Practices
|

@@ -278,6 +313,24 @@ Here is some technical advice for you.
|
||||
- Use `main_content_only=true` to avoid navigation/ads
|
||||
- Choose an appropriate `extraction_type` for your use case
|
||||
|
||||
### 5. Prompt Injection Protection
|
||||
The MCP server automatically sanitizes scraped content when `main_content_only` is enabled (the default). This strips hidden content that malicious websites could use to inject instructions into the AI's context:
|
||||
|
||||
- **CSS-hidden elements**: `display:none`, `visibility:hidden`, `opacity:0`, `font-size:0`, `height:0`, `width:0`
|
||||
- **Accessibility-hidden elements**: `aria-hidden="true"`
|
||||
- **Template tags**: `<template>` elements
|
||||
- **HTML comments**: `<!-- ... -->`
|
||||
- **Zero-width characters**: Invisible unicode characters like zero-width spaces
|
||||
|
||||
This protection runs automatically on all MCP tool responses. Keep `main_content_only=true` (the default) for maximum protection.
|
||||
|
||||
### 6. Use Sessions for Multiple Requests
|
||||
- Use `open_session` to create a persistent browser session when scraping multiple pages
|
||||
- Pass the `session_id` to `fetch` or `stealthy_fetch` calls to reuse the same browser
|
||||
- Always close sessions with `close_session` when done to free resources
|
||||
- Use `list_sessions` to check which sessions are still active
|
||||
- A `session_id` from a dynamic session can only be used with `fetch`/`bulk_fetch`, and a stealthy session can only be used with `stealthy_fetch`/`bulk_stealthy_fetch`

### Capturing XHR/Fetch Requests
|

|

Many SPAs load data through background API calls (XHR/fetch). You can capture these requests by passing a regex URL pattern to `capture_xhr` at the session level:
|
||||
|
||||
```python
|
||||
from scrapling.fetchers import DynamicSession
|
||||
|

with DynamicSession(capture_xhr=r"https://api\.example\.com/.*", headless=True) as session:
|

page = session.fetch('https://example.com')

print(xhr.url, xhr.status)
|
||||
print(xhr.body) # Raw response body as bytes
|
||||
```
|
||||
|
||||
Each item in `captured_xhr` is a full `Response` object with the same properties (`.url`, `.status`, `.headers`, `.body`, etc.). When `capture_xhr` is not set or is `None`, `captured_xhr` is an empty list.

4. The **session** fetches the page and returns a [Response](../fetching/choosing.md#response-object) object to the **Crawler Engine**. The engine records statistics and checks for blocked responses. If the response is blocked, the engine retries the request up to `max_blocked_retries` times. Of course, the blocking detection and the retry logic for blocked requests can be customized.
|
||||
5. The **Crawler Engine** passes the [Response](../fetching/choosing.md#response-object) to the request's callback. The callback either yields a dictionary, which gets treated as a scraped item, or a follow-up request, which gets sent to the scheduler for queuing.
|
||||
6. The cycle repeats from step 2 until the scheduler is empty and no tasks are active, or the spider is paused.

7. If `crawldir` is set while starting the spider, the **Crawler Engine** periodically saves a checkpoint (pending requests + seen URLs set) to disk.

If you have been doing Web Scraping for a long time, you probably noticed that there are repeating problems with Web Scraping, like:
|
||||
|
||||
1. **Rapidly changing website structures** — Sites frequently update their DOM structures, breaking static XPath/CSS selectors.
|
||||
2. **Unstable selectors** — Class names and IDs often change or use randomly generated values that break scrapers or make scraping these websites difficult.
|
||||
3. **Increasingly complex anti-bot measures** — CAPTCHA systems, browser fingerprinting, and behavior analysis make traditional scraping difficult

If you start thinking about bigger goals like Broad Scraping or Generic Web Scraping, or what you like to call it, then the above issues intensify, and you will face new issues like:

1. **Extreme Website Diversity** — Generic scraping must handle countless variations in HTML structures, CSS usage, JavaScript frameworks, and backend technologies.
|

2. **Identifying Relevant Data** — How does the scraper know what data is important on a page it has never seen before?

### Solving issue T3: Increasingly complex anti-bot measures
|
||||
It's well known that creating an undetectable spider requires more than residential/mobile proxies and human-like behavior. It also needs a hard-to-detect browser, which Scrapling provides two main options to solve:
|
||||
|
||||
1. [DynamicFetcher](https://scrapling.readthedocs.io/en/latest/fetching/dynamic.html) — This fetcher provides flexible browser automation with multiple configuration options and little under-the-hood stealth improvements.
|
||||
2. [StealthyFetcher](https://scrapling.readthedocs.io/en/latest/fetching/stealthy.html) — Because we live in a harsh world and you need to take [full measure instead of half-measures](https://www.youtube.com/watch?v=7BE4QcwX4dU), `StealthyFetcher` was born. This fetcher uses our stealthy browser -- a version of [DynamicFetcher](https://scrapling.readthedocs.io/en/latest/fetching/dynamic.html) that nearly bypasses all annoying anti-protections, provides tools to handle the rest, and automatically bypasses all types of Cloudflare's Turnstile/Interstitial!

### Solving issue B3: Pagination variations
|
||||
This issue, Scrapling currently doesn't have a direct method to automatically extract pagination's URLs for you, but it will be added with the upcoming updates :)
|
||||
|
||||
But you can handle most websites if you search for the most common patterns with `page.find_by_text('Next')['href']` or `page.find_by_text('load more')['href']` or selectors like `'a[href*="?page="]'` or `'a[href*="/page/"]'`—you get the idea.

:param useragent: Pass a useragent string to be used. Otherwise the fetcher will generate a real Useragent of the same browser and use it.
|
||||
:param cdp_url: Instead of launching a new browser instance, connect to this CDP URL to control real browsers through CDP.
