Firecrawl Search

Security checks across malware telemetry and agentic risk

Overview

This skill is a straightforward Firecrawl API wrapper for user-directed web search, scraping, and crawling, with no evidence of hidden persistence, destructive behavior, or unrelated data access.

Install only if you are comfortable sending search terms, target URLs, and retrieved page content to Firecrawl using your API key. Avoid submitting secrets, token-bearing links, internal-only systems, private documents, or regulated data unless your organization has approved that Firecrawl use.

MCP Least Privilege
Confidence
95% confidence
Finding
The skill documentation advertises use of an environment variable and outbound web/API access, but it does not declare corresponding permissions. This creates a transparency and governance gap: users or orchestrators may invoke a skill with broader capabilities than expected, increasing the risk of unintended network egress or access to secrets.

Missing User Warnings

Medium
Confidence
97% confidence
Finding
The skill encourages users to submit search queries and URLs to Firecrawl, but it does not clearly warn that this data is sent to an external third-party API. That omission can lead to inadvertent disclosure of sensitive queries, internal URLs, or proprietary targets, especially in agent workflows where users may assume processing is local.
