Returns the full signature of a method including return type and parameters.
AI agents call get_method_signature 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 is a query operation that retrieves metadata about APK methods for analysis purposes. It has no side effects, cannot modify code or data, and poses minimal security risk even if called arbitrarily by an agent. The worst outcome is unnecessary API calls or information disclosure of method signatures already accessible through static analysis of the APK.
From the tool's definition Tool returns method signature information (return type and parameters) with no modification capability. Described as 'Returns' indicating data retrieval only, consistent with Read category operations like 'get' and 'fetch'.
Attacks that exploit this kind of access
Returns the full signature of a method including return type and parameters. 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_method_signature: 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_method_signature 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_method_signature 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_method_signature. 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_method_signature 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.
