Question 1

How to integrate GraphQL Cop into a CI/CD pipeline?

Accepted Answer

Use the JSON output option (-o json) to parse results programmatically, and run it via Docker or Python scripts. The tool's exit codes and structured output allow easy integration with build systems to fail on high-severity findings.

Question 2

GraphQL Cop vs GraphQL Armor: which should I use?

Accepted Answer

GraphQL Cop is a scanning tool for detecting vulnerabilities, while GraphQL Armor is a runtime protection library. Use GraphQL Cop for auditing and GraphQL Armor for active mitigation; they complement each other in a security strategy.

Question 3

Does GraphQL Cop test for authentication bypass vulnerabilities?

Accepted Answer

No, it focuses on common GraphQL issues like DoS, CSRF, and information leaks. It supports custom headers for testing authenticated endpoints, but doesn't specifically scan for authentication flaws beyond basic CSRF checks.

Question 4

How to exclude false positives in GraphQL Cop?

Accepted Answer

Use the -e flag to exclude specific tests by name (e.g., -e field_duplication). First, list available tests with -l to identify which ones to skip, helping tailor scans to your API's context.

Question 5

Can GraphQL Cop be used with proxies like Burp Suite?

Accepted Answer

Yes, it supports proxies via the -x flag (e.g., --proxy=http://127.0.0.1:8080). This allows intercepting and inspecting requests, useful for debugging or integrating with existing security testing workflows.

Question 6

What Denial of Service attacks does GraphQL Cop check for?

Accepted Answer

It detects alias overloading, batch queries, field duplication, and directive overloading—all GraphQL-specific DoS vectors that exploit query complexity to overload servers, as outlined in the detections.
