# Scrapling MCP Server
22

3-
The Scrapling MCP server exposes nine web scraping tools over the MCP protocol. It supports CSS-selector-based content narrowing (reducing tokens by extracting only relevant elements before returning results), three levels of scraping capability (plain HTTP, browser-rendered, and stealth/anti-bot bypass), and persistent browser session management.

The Scrapling MCP server exposes ten tools over the MCP protocol. It supports CSS-selector-based content narrowing (reducing tokens by extracting only relevant elements before returning results), three levels of scraping capability (plain HTTP, browser-rendered, and stealth/anti-bot bypass), persistent browser session management, and page screenshots returned as real image content blocks.

All scraping tools return a `ResponseModel` with fields: `status` (int), `content` (list of strings), `url` (str).

Start with `get` (fastest, lowest resource cost). Escalate to `fetch` if content requires JS rendering. Escalate to `stealthy_fetch` only if blocked. For multiple pages from the same site, use a persistent session to avoid browser launch overhead.
