What is the primary command for this skill?

You can trigger the fuzzing process within Claude Code using the /fuzz-api command followed by your target endpoint or parameters.

What types of vulnerabilities can it find?

It is designed to identify SQL injection, Cross-Site Scripting (XSS), command injection, input validation failures, and edge-case boundary errors.

Does it support SQL injection detection?

Yes, the skill specifically generates common and complex SQL injection payloads to test how your API and database handle malformed queries.

Can I use this for production APIs?

Fuzzing involves sending many malformed requests which can be disruptive; it is highly recommended to use this skill in staging or local development environments.

Security & Testing

Automates security fuzz testing for REST APIs to identify vulnerabilities like SQL injection, XSS, and input validation failures.

About

This skill empowers Claude to perform deep security assessments on API endpoints by generating and injecting malformed data, random payloads, and boundary values. It is designed to expose robustness issues and security flaws—such as command injection or unexpected crashes—that traditional testing might miss, providing a detailed analysis of API responses to help developers secure their backend services and ensure data integrity.

Key Features

Real-time API response analysis to identify crashes and unexpected behavior
Boundary value and malformed input analysis for parameter stress-testing
Automated payload generation for SQLi and XSS vulnerability testing
Integration-ready security assessment reporting
3 GitHub stars
Targeted fuzzing for specific endpoints and individual parameters

Use Cases

Validating API robustness against extreme numeric values or non-numeric characters
Performing automated security audits during the API development lifecycle
Detecting SQL injection vulnerabilities on sensitive database-driven endpoints
