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

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

## Why strings_extract is rated Low

This tool performs static analysis (string extraction) on binary files, which is a read-only operation that retrieves information without modifying or executing code. However, in the context of a penetration testing platform, the severity is elevated to medium because extracted strings may reveal sensitive information (credentials, API keys, hardcoded paths) that could be leveraged for further attacks.

From the tool's own definition: "Tool name 'strings_extract' and description 'Extract strings from a binary file with enhanced logging' indicates data retrieval with no modification or execution of the target binary."

## Use case

AI agents call strings_extract to retrieve information from Nyxstrike 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 Nyxstrike:

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