What is firecrawl-scraper?

A skill for using the Firecrawl version 2 API, a service that crawls websites and converts their pages into Markdown or structured data. Markdown is plain text with simple formatting, while structured data is arranged in fields that software can process.

Scraping individual pages, crawling whole websites, extracting web content, and building web-data pipelines.

It avoids having to build every part of a website scraper yourself, including crawling pages and handling JavaScript-rendered content. It prepares web content in forms suitable for language-model workflows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00170	$0.04108
Opus 5.5	$0.00068	$0.01643

Security

Grade B, and why

firecrawl-scraper scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

const response = await fetch('https://api.firecrawl.dev/v2/scrape', { method: 'POST',

Not a fault in itself. Listed so you know the mod talks to something, and to what.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
