WHAT IT DOES

What list_class_members does on Android Source Explorer MCP Server

AI agents call list_class_members to retrieve information from Android Source Explorer MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why list_class_members needs a policy

This is purely an information retrieval operation. It queries class metadata (methods and fields) without side effects, modifications, or code execution. Listing class members is analogous to reading documentation or inspecting code structure. The 'list' verb combined with the static nature of class inspection confirms Read category with low severity.

From the tool's definition The tool 'list_class_members' retrieves and lists method and field signatures for a given class. The description explicitly states it 'lists' (retrieve-only operation) rather than modifying, creating, or deleting anything.

POLICY

How to control list_class_members

PolicyLayer is an MCP gateway — it sits between your AI agents and Android Source Explorer MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_class_members:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_class_members": {}
  }
}

list_class_members is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
