Browser Use API

Security checks across malware telemetry and agentic risk

Overview

This skill appears to do what it says: send browser automation tasks to Browser Use's cloud API, with no artifact-backed evidence of hidden persistence, destructive behavior, or unauthorized endpoints.

Install only if you intend to use Browser Use's cloud service. Treat task text, URLs, page contents, screenshots, logs, and extracted results as potentially visible to that provider, and do not use it for secrets, regulated data, or private internal systems unless that data handling is approved.

MCP Least Privilege
Confidence
91% confidence
Finding
The skill advertises and demonstrates shell execution via curl and a helper script, but it does not declare corresponding permissions. That mismatch weakens platform trust boundaries because users or orchestrators may not realize the skill can invoke shell commands and send data externally.

Missing User Warnings

Medium
Confidence
96% confidence
Finding
The skill description says it is a cloud browser automation skill, but it does not clearly warn that user prompts, target URLs, browsing actions, screenshots, and extracted page data are sent to a third-party remote service. This can cause unintentional disclosure of sensitive information when users assume browsing is local or private.
