Compare scan results by two hashes.
AI agents call compareApps to retrieve information from APK Security Guard MCP Suite without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only comparison of historical scan data. It retrieves and presents analysis results without side effects, code execution, data modification, or destruction. The operation is informational in nature, supporting security analysis review rather than performing active security testing or system modifications.
From the tool's definition 'Compare scan results by two hashes' is a retrieval and comparison operation that queries existing scan results without modifying, deleting, or executing any code. The tool reads and presents data from previous APK security scans.
