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

```json
{
  "jsonrpc": "2.0",

## Why waf_run_self_tests is rated High

This tool executes pre-defined security test payloads against the WAF engine. While the payloads are curated samples rather than arbitrary code, the tool triggers execution of attack vectors (SQL injection, XSS, command injection, path traversal) through the system.

From the tool's own definition: "Tool description states it 'runs built-in SQLi/XSS/command injection/path traversal samples' (translated from Chinese: '运行内置 SQLi/XSS/命令注入/路径遍历样例'). The term '运行' (run) and the reference to executing test payloads indicates code/command execution."

## Use case

AI agents invoke waf_run_self_tests to trigger actions in Hospital WAF MCP. 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 Hospital WAF MCP:

```json

  "version": "1",
  "default": "deny",
  "tools": {
    "waf_run_self_tests": {
      "limits": [
        {

          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
