Returns the inheritance hierarchy of a class.
AI agents call get_class_hierarchy 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 retrieves static analysis information about class hierarchies within an APK without modifying any data, executing code, or causing side effects. It is a pure information query typical of static analysis tools. The blast radius of misuse is minimal—an agent could at worst learn about an APK's structure, which is already visible through decompilation and other read operations on this server.
From the tool's definition Tool name and description indicate a retrieval operation: 'Returns the inheritance hierarchy of a class.' The verb 'returns' and the read-only nature of querying class structure metadata confirm no data modification, deletion, or code execution occurs.
Attacks that exploit this kind of access
Returns the inheritance hierarchy of a class. It is categorised as a Read tool in the APK Security Guard MCP Suite MCP Server, which means it retrieves data without modifying state.
Register the APK Security Guard MCP Suite MCP server in PolicyLayer and add a rule for get_class_hierarchy: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches APK Security Guard MCP Suite. Nothing to install.
get_class_hierarchy is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_class_hierarchy rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_class_hierarchy. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_class_hierarchy is provided by the APK Security Guard MCP Suite MCP server (zmbcen/apk-security-guard-mcp-suite). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
