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

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

## Why memory_mono_objects is rated Low

Reads memory state without modification; potential sensitive data exposure via heap inspection.

From the tool's own definition: "Find live Mono objects, scans heap regions, returns object addresses"

## Use case

AI agents call memory_mono_objects 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_mono_objects": {}
  }
}
```
