Returns only the source code block of a specific method within a class.
AI agents call get_method_code to retrieve information from Jadx MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves decompiled source code for inspection purposes. It reads existing data (the method's decompiled source) without creating, modifying, deleting, or executing anything. The worst-case misuse by an agent would be information disclosure of code logic, which is a read-level risk. No financial, destructive, or execution capabilities are present.
From the tool's definition Tool name and description indicate retrieval only: 'Returns only the source code block of a specific method' — a fetch/query operation with no mutation or side effects. No arguments suggest code execution or state modification.
Documented attack patterns abuse exactly the kind of access get_method_code gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Jadx MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_method_code:
{
"version": "1",
"default": "deny",
"tools": {
"get_method_code": {}
}
}get_method_code is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Returns only the source code block of a specific method within a class. It is categorised as a Read tool in the Jadx MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Jadx MCP Server MCP server in PolicyLayer and add a rule for get_method_code: 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 Jadx MCP Server. Nothing to install.
get_method_code 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_code 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_code. 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_code is provided by the Jadx MCP Server MCP server (mobilehackinglab/jadx-mcp-plugin). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Jadx MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
