Crypto Whale Monitor

Security checks across malware telemetry and agentic risk

Overview

This skill coherently checks public Ethereum wallet balances through an RPC endpoint and does not install persistence or perform hidden actions by itself.

Install only if you are comfortable sending monitored wallet addresses to the configured Ethereum RPC provider. Use a limited-purpose RPC key if RPC_URL includes credentials, and create a cron job only if you intentionally want ongoing background monitoring.

MCP Least Privilege
Confidence
70% confidence
Finding
Without declared permissions the skill's intent is opaque and cannot be validated.

Natural-Language Policy Violations

Low
Confidence
95% confidence
Finding
The output explicitly hard-codes `toLocaleString('en-US', ...)`, which imposes a specific language/locale choice on all users. This is a natural-language/locale policy issue because the skill does not offer a user choice or document why a U.S. locale is required.
