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

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

## Why graphql_scanner is rated High

The description is empty, so classification relies on the tool name and server context. A GraphQL scanner actively probes and queries GraphQL endpoints to discover schema, identify misconfigurations, and find vulnerabilities. Given the offensive security context of this server (attack suite generation, payload generation, vulnerability assessment), this tool likely executes active scanning operations against targets.

From the tool's own definition: "Tool name 'graphql_scanner' on a security recon server with sibling tools like 'advanced_payload_generation', 'ai_generate_attack_suite', and 'ai_vulnerability_assessment'"

## Use case

AI agents invoke graphql_scanner to trigger actions in Pengstrike. 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 Pengstrike:

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