Amazon Asin Lookup Api Skill

Security checks across malware telemetry and agentic risk

Overview

This appears to be a real Amazon product lookup skill, but it asks users to provide a BrowserAct API key through chat if the environment variable is missing.

Review before installing. Use this only if you are comfortable sending ASIN lookup requests through BrowserAct. Configure BROWSERACT_API_KEY through environment or secret storage; do not paste the API key into chat, prompts, logs, or shared transcripts.

MCP Least Privilege

Finding
The skill instructs the agent to run a Python script that uses an environment variable API key and performs external network access, yet the skill declares only metadata requirements instead of explicit permissions. This creates a trust gap: an agent or reviewer may underestimate the skill's ability to access secrets and send data off-box, increasing the risk of unintended secret exposure or unauthorized network operations.
