# test_api_security

Run API security testing (REST + GraphQL) following OWASP API Top 10. Tests for: BOLA/IDOR, JWT alg-confusion, OAuth callback validation, rate-limit bypass, mass assignment, GraphQL introspection. Returns immediately with engagement_id; agent runs asynchronously.

- Homepage: https://github.com/0xSteph/pentest-ai

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

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

## Why test_api_security is rated High

This tool actively executes security tests against live API endpoints, including exploitation techniques like JWT algorithm confusion, OAuth callback manipulation, and IDOR probing. These are real offensive operations against external systems. While framed as a pentest tool, misuse could trigger unintended side effects on target systems (rate-limit abuse, unauthorized data access via IDOR).

From the tool's own definition: "Run API security testing (REST + GraphQL) following OWASP API Top 10. Tests for: BOLA/IDOR, JWT alg-confusion, OAuth callback validation, rate-limit bypass, mass assignment, GraphQL introspection."

## Use case

AI agents invoke test_api_security to trigger actions in Pentest Ai. 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 Pentest Ai:

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