China Check

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent read-only company lookup helper that uses a disclosed external China-Check MCP service, with privacy considerations for submitted search terms.

Before installing, understand that company lookup queries are sent to China-Check's remote MCP service. Avoid submitting confidential investigation context or personal phone numbers unless that disclosure is acceptable, and independently verify mission-critical registry information with official sources.
