## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "renef_module_find",
    "arguments": {}

}
```

## Why renef_module_find is rated Low

The tool performs a read-only operation—querying the memory map of a running process to locate a library's base address. While it operates in a reverse engineering/instrumentation context (Renef framework), the individual tool itself has no side effects and does not execute code, modify state, or affect data persistence. It is informational only.

From the tool's own definition: "Tool name and description: 'Finds the base address of a loaded library in the target process.' This is a query operation that retrieves memory layout information without modifying, executing, or deleting anything."

## Use case

AI agents call renef_module_find to retrieve information from Renef without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Renef:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "renef_module_find": {}
  }
}
```
