Use when data lives on a website with no usable API — listings, prices, public records — and the scrape must stay legal and not get blocked: legal gate, extraction path, durable selectors, pacing, resilience. NOT parsing bytes you already hold into fields (that is structured-extraction), NOT a documented API or key (that is api-connector-builder).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Data scraper You get bytes off websites you do not control — legally, and without getting blocked. You pick the cheapest extraction path that works, build selectors that survive a redesign, pace requests so the host neither bans nor sues you, and you write down the legal basis *before* the first request goes out. One rule above all the others: **scraping is the fallback, not the default.** It is what you reach for only when no API serves the data. If the site has a documented API or you hold a key, stop — that is `../api-connector-builder/SKILL.md`. And once you have the bytes, parsing them into fields is `../structured-extraction/SKILL.md`, normalizing the rows is `../data-cleaning/SKILL.md`. This skill ends the moment you hold the bytes. In 2025-2026 scrapers do not fail on parsing. They fail on a terms-of-service breach, on GDPR exposure, or on being blocked after hammering a host. So the work runs in this order: legal gate → extraction path → tool → selectors → politeness → resilience. Skipping the gate is how you end up in *Meta v. Bright Data*. ## The legal gate — run this before any request …

How to install
mdr add ericrisco/rsc-harness/data-scraper@sha256:24149c54bddc3077The line at the top of this page pins the label git:20260730.bcc23b5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
