Is this skill suitable for production APIs?

Because fuzzing involves sending unexpected data that may cause crashes or data corruption, it should primarily be used in staging or development environments.

How do I trigger the fuzzing process?

You can invoke the skill by using the /fuzz-api command within Claude Code and specifying the target endpoint or parameters.

What is the api-fuzzer skill?

It is a specialized capability for Claude Code that automates the process of sending malformed inputs to APIs to discover security bugs and stability issues.

Can I use this for automated testing?

Yes, this skill is ideal for integration into security audits and CI/CD pipelines to ensure continuous protection against vulnerabilities.

Which vulnerabilities can this skill detect?

The skill is designed to identify SQL injection, Cross-Site Scripting (XSS), command injection, and general input validation failures.

Security & Testing

Automates REST API fuzz testing to identify security vulnerabilities, input validation failures, and unexpected edge cases.

About

The API Security Fuzzer skill empowers Claude to perform automated, deep-dive testing of REST APIs by injecting malformed data, boundary values, and randomized payloads into specific endpoints. By analyzing server responses for signs of crashes or unexpected behavior, it helps developers proactively uncover critical vulnerabilities like SQL injection, XSS, and command injection before they can be exploited. This skill is essential for strengthening API robustness, ensuring strict input validation, and maintaining a secure software development lifecycle during the testing phase.

Key Features

Automated payload generation for SQLi, XSS, and command injection
Boundary value and malformed data testing for robust validation
Real-time analysis of API responses to detect crashes and errors
Support for targeted testing of specific parameters and endpoints
Compatibility with CI/CD pipelines for automated security audits
1 GitHub stars

Use Cases

Stress-testing API input validation with extreme or non-numeric data
Detecting SQL injection vulnerabilities in user-facing endpoints
Performing comprehensive security audits on RESTful backend services
