Scrapling Skill (VCO)
Scrapling is a Python-based web scraping / extraction toolkit that exposes:
- a CLI (
scrapling ...) for fetching + extracting content into files
- an optional MCP server (
scrapling mcp) so an agent can call structured scraping tools
This skill is CLI-first. Prefer it when you already have URLs and need reliable, repeatable extraction (CSS selector → file).
When to use
Use scrapling when you need:
- Extract specific parts of a web page (CSS selector / XPath) into
.txt / .md / .html
- Run repeatable scraping jobs (batch URLs with a small wrapper script)
- Reduce token usage by extracting only the relevant DOM region before passing to the LLM
- Provide a local MCP endpoint for scraping tools (agent → MCP → scrapling)
Boundaries (vs Playwright / Search)
vs playwright
scrapling: best for “get URL → extract selector → write file” workflows; simpler, faster iterationplaywright: best for interactive UI flows (login, multi-step navigation, downloads, complex JS actions, stateful sessions)
If you must navigate or click through a UI, use playwright.
If you can directly fetch the target page and just need extraction, use scrapling.
vs search tools
- Search tools are for discovering sources/URLs (query → result list → choose URLs).
scrapling is for acquisition + extraction once you already know the URL(s).
A common pipeline:
- Search → find candidate URLs
- Scrapling → extract focused content from chosen URLs
Prerequisite check (required)
- Python version (Scrapling requires Python >= 3.10):
- Scrapling CLI availability:
Installation (recommended)
Scrapling’s CLI and MCP features are enabled via extras.
Recommended (CLI + MCP + fetchers):
python -m pip install "scrapling[ai]"
If you only want CLI fetch/extract without MCP:
python -m pip install "scrapling[fetchers]"
If you use browser-based fetchers, you may need browser binaries:
# Option A: via Scrapling helper (after install)
scrapling install
# Option B: directly via Playwright
python -m playwright install
Wrapper script (Windows convenience)
This skill ships a thin PowerShell wrapper:
C:/Users/羽裳/.codex/skills/scrapling/scripts/scrapling.ps1
It checks whether scrapling exists and prints install hints if missing.
Common CLI patterns
1) Extract full page body (to Markdown)
scrapling extract get "https://example.com" out.md
2) Extract a specific element (CSS selector) to text
scrapling extract get "https://example.com" out.txt --css-selector "main article"
3) Extract HTML for downstream parsing
scrapling extract get "https://example.com" out.html --css-selector "#content"
4) Use browser-backed fetcher mode (when simple GET is blocked / dynamic)
scrapling extract fetch "https://example.com" out.md --css-selector "main"
Tip: keep outputs in files and only feed the smallest relevant snippet to the LLM.
MCP server relationship (optional)
Scrapling can run as an MCP server. This is useful when:
- the agent needs tool-style scraping calls
- you want scraping results to be structured and deterministic
Start MCP server (stdio transport by default):
Optional: run MCP server with HTTP transport:
scrapling mcp --http --host 127.0.0.1 --port 8765
Example MCP server config snippet
{
"servers": {
"scrapling": {
"mode": "stdio",
"command": "scrapling",
"args": ["mcp"],
"required": false,
"note": "Requires: python -m pip install \"scrapling[ai]\""
}
}
}
Safety & ops notes
- Prefer selector-based extraction to minimize data volume.
- Treat scraping as an external dependency: handle timeouts, retries, and failures explicitly.
- For aggressive bot protection, consider switching fetchers or using
playwright.
