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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "memory_rtti_info",
    "arguments": {}
  }
}
```

## Why memory_rtti_info is rated Low

Tool reads and parses memory type information without modifying or executing anything.

From the tool's own definition: "Parse MSVC RTTI...Reads vtable pointer, extracts class name"

## Use case

AI agents call memory_rtti_info to retrieve information from Jshookmcp 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 Jshookmcp:

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