# Scrapling MCP Server
|
|
|
|
The Scrapling MCP server exposes six web scraping tools over the MCP protocol. It supports CSS-selector-based content narrowing (reducing tokens by extracting only relevant elements before returning results) and three levels of scraping capability: plain HTTP, browser-rendered, and stealth (anti-bot bypass).
|
|
|
|
All tools return a `ResponseModel` with fields: `status` (int), `content` (list of strings), `url` (str).
|
|
|
|
## Tools
|
|
|
|
### `get` -- HTTP request (single URL)
|
|
|
|
Fast HTTP GET with browser fingerprint impersonation (TLS, headers). Suitable for static pages with no/low bot protection.
|
|
|
|
**Key parameters:**
|

|
|
| `follow_redirects` | bool | true | Follow HTTP redirects |
|
|

### `bulk_get` -- HTTP request (multiple URLs)
|

Async concurrent version of `get`. Same parameters except `url` is replaced by `urls` (list of strings). All URLs are fetched in parallel. Returns a list of `ResponseModel`.
|
|

|
|

|
### `stealthy_fetch` -- Stealth browser fetch (single URL)
|

## Tool selection guide
|
|
|
|
| Scenario | Tool |
|
|
|------------------------------------------|---------------------------------------------------------------|
|
|
| Static page, no bot protection | `get` |
|
|
| Multiple static pages | `bulk_get` |
|
|
| JavaScript-rendered / SPA page | `fetch` |
|
|
| Multiple JS-rendered pages | `bulk_fetch` |
|
|
| Cloudflare or strong anti-bot protection | `stealthy_fetch` (with `solve_cloudflare=true` for Turnstile) |
|
|
| Multiple protected pages | `bulk_stealthy_fetch` |
|
|
|
|
Start with `get` (fastest, lowest resource cost). Escalate to `fetch` if content requires JS rendering. Escalate to `stealthy_fetch` only if blocked.
|
|
|
|
## Content extraction tips
|
|
|
|
- Use `css_selector` to narrow results before they reach the model -- this saves significant tokens.
|
|
- `main_content_only=true` (default) strips nav/footer by restricting to `<body>`.
|
|
- `extraction_type="markdown"` (default) is best for readability. Use `"text"` for minimal output, `"html"` when structure matters.
|
|
- If a `css_selector` matches multiple elements, all are returned in the `content` list.
|
|
|
|
## Setup
|
|
|
|
Start the server (stdio transport, used by most MCP clients):
|
|
|
|
```bash
|
|
scrapling mcp
|
|
```
|
|
|
|
Or with Streamable HTTP transport:
|
|
|
|
```bash
|
|
scrapling mcp --http
|
|
scrapling mcp --http --host 127.0.0.1 --port 8000
|
|
```
|
|
|
|
Docker alternative:
|
|
|
|
```bash
|
|
docker pull pyd4vinci/scrapling
|
|
docker run -i --rm scrapling mcp
|
|
```
|
|
|
|
The MCP server name when registering with a client is `ScraplingServer`. The command is the path to the `scrapling` binary and the argument is `mcp`. |
