Scrapfly Screenshot

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward guide for using Scrapfly to take website screenshots, with expected third-party API use and no hidden execution or persistence.

Install only if you are comfortable sending target URLs, rendered page contents, and screenshots to Scrapfly. Avoid using it for private dashboards, authenticated sessions, regulated data, or pages containing visible secrets unless you have approval, and keep any custom JavaScript narrow and reviewable.

Missing User Warnings

Medium
Confidence
97% confidence
Finding
The skill clearly directs users to send arbitrary target URLs and page content to Scrapfly's third-party screenshot service, and the notes explicitly state screenshots are stored remotely and retrievable via a response header. Failing to warn users about third-party transmission and remote retention can cause unintended disclosure of sensitive internal URLs, page contents, or authenticated views if the skill is used on private resources.

External Transmission

Medium
Category

Content
## API Reference

**Endpoint:** `GET https://api.scrapfly.io/screenshot`

### ScrapflyClient
Confidence
91% confidence
Finding
This skill is explicitly built around transmitting user-supplied URLs to an external API endpoint, so the external transmission is real and central to its function. In this context the danger is not hidden exfiltration but the absence of strong disclosure and safeguards around sending potentially sensitive browsing targets and page renders to a third party.
