Search methods by their return type.
AI agents call search_method_by_return_type 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 search/query operation on APK analysis data to locate methods matching specific return type criteria. It retrieves information without side effects, creating new data, executing code, deleting data, or moving money. The 'search' action is explicitly read-only. Severity is low because misuse would only expose analysis metadata, not enable arbitrary code execution or data destruction.
From the tool's definition Tool name 'search_method_by_return_type' and description 'Search methods by their return type' indicate a query operation that retrieves or filters data without modifying state.
