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

  "jsonrpc": "2.0",

## Why frida_get_messages is rated Low

This tool queries state from an already-injected script (retrieving pending messages). It has no side effects beyond reading—it does not modify, delete, execute code, move money, or trigger external operations. The most severe impact would be information disclosure if sensitive data is exposed in the messages, but that is a read-level concern.

From the tool's own definition: "Tool name includes 'get_messages' and description states 'Retrieve and drain pending messages from an injected script.' The verbs 'retrieve' and 'drain' indicate data retrieval without modification or destruction."

## Use case

AI agents call frida_get_messages to retrieve information from Ya Frida 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 Ya Frida:

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