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

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

## Why scan_value is rated Low

Based on the tool name and server context, scan_value likely performs memory scanning to find values in a process's memory space. Scanning/searching is a Read operation with no direct side effects. However, it operates on potentially sensitive process memory, elevating severity to medium. Confidence is reduced due to the empty description.

From the tool's own definition: "Tool name is 'scan_value'; description is empty. Server description mentions 'memory scanning' as a capability, and this tool name aligns with scanning memory for values."

## Use case

AI agents call scan_value to retrieve information from Frida Game Hacking MCP 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 Frida Game Hacking MCP:

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