What GraphQL-Cop is
GraphQL-Cop is a free Python utility for checking GraphQL APIs for common security issues, including as part of CI/CD checks. Its tests cover alias and batch query overloading, CSRF risks, information leaks, duplicated fields, denial-of-service risks, and circular introspection queries. When it finds vulnerabilities, it can provide cURL commands for reproducing them; results can be output as JSON and include those commands. Users can supply request headers, exclude tests, force a scan, configure a proxy, or provide a custom endpoint wordlist. If a target URL has no GraphQL path, the tool tries common paths. It runs from Python or as a Docker container and requires Python 3 and the Requests library. The repository includes an MIT License and command-line help, including troubleshooting guidance for Docker and dependency issues. It is available for Linux, macOS, Windows, and self-hosted use. It does not cover API discovery, authentication or authorization, input validation, or business-logic testing.
Good
- Checks for several GraphQL security risks.
- Can output JSON with cURL reproductions.
- Supports custom headers, proxies, and endpoint lists.
- Runs from Python or Docker.
- Free and licensed under MIT.
Watch out
- Does not test authentication or authorization.
- Does not cover API discovery.
- Does not test input validation or business logic.
Who it suits
It suits developers and security teams looking for lightweight checks of GraphQL APIs, including in CI/CD workflows. Its stated testing scope is focused on common GraphQL security issues rather than broader API testing.
Verdict
GraphQL-Cop offers configurable checks and reproducible findings for a focused set of GraphQL risks. Its stated exclusions matter if a review also needs discovery, access-control, input-validation, or business-logic coverage.
