Firecrawler

Security checks across malware telemetry and agentic risk

Overview

Firecrawler is a disclosed Firecrawl web-scraping helper whose API-key, network, and output-file behavior fits its stated purpose.

Install only if you are comfortable sending requested URLs, search terms, schemas, and extraction prompts to Firecrawl. Use reasonable crawl limits, avoid private or sensitive URLs unless Firecrawl is approved for that data, and consider pinning the Firecrawl SDK version in your environment.

Medium

Category: MCP Least Privilege
Confidence: 92% confidence
Finding: The skill documentation and usage clearly indicate access to environment variables (API key), network operations (web scraping/search/crawl), and file writes (screenshots/output docs), yet no permissions are explicitly declared. This creates a transparency and policy-enforcement gap: an agent or reviewer may authorize the skill without understanding its actual capabilities, increasing the risk of unintended external requests or local file modification.
