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

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

## Why one_gadget_search is rated High

'one_gadget' in the security/CTF context specifically refers to a tool that identifies exploitable gadgets in binary libraries to achieve code execution. On an offensive security platform alongside payload generation and attack suite tools, this almost certainly executes or facilitates exploit development.

From the tool's own definition: "Tool name 'one_gadget_search' on a penetration testing platform; description is empty. 'one_gadget' is a well-known offensive security tool that finds ROP gadgets usable for exploit development (e.g., spawning shells via a single gadget in libc)."

## Use case

AI agents invoke one_gadget_search to trigger actions in Nyxstrike. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Nyxstrike:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "one_gadget_search": {
      "limits": [
        {
          "counter": "one_gadget_search_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
