Amazon Asin Lookup Api Skill

Security checks across malware telemetry and agentic risk

Overview

The skill appears to be a legitimate Amazon ASIN lookup integration, but it gives unsafe guidance for handling an API key.

Install only if you are comfortable sending lookup requests to BrowserAct. Configure the BrowserAct key through environment or secret storage, and do not paste the API key into chat, prompts, logs, or shared transcripts.

MCP Least Privilege
Confidence
88% confidence
Finding
The skill invokes a Python script that uses an environment secret (`BROWSERACT_API_KEY`) and makes external network/API requests, but it does not declare corresponding permissions. This creates a transparency and policy-enforcement gap: an agent or reviewer may treat the skill as lower risk than it really is, while the skill can still access secrets and transmit user-provided ASINs and retrieved data to a third-party service.

Missing User Warnings

High
Confidence
99% confidence
Finding
The script explicitly tells users they can provide the BrowserAct API key 'in the chat', which encourages disclosure of a sensitive credential through an unsafe channel. In an agent/skill context, this is especially dangerous because chat content may be logged, retained, or exposed to other components, creating a real risk of credential theft and subsequent abuse of the BrowserAct account.
