Designs API security tests mapped to the OWASP API Security Top 10 (2023 edition). Use when an SDET says "test our API for BOLA", "check the OWASP API Top 10", "is this endpoint leaking data", "test mass assignment", or pastes an OpenAPI spec. Produces BOLA, auth, property-level, rate-limit and function-level tests as pytest drafts for authorized testing of your own API, which the engineer runs against staging.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# OWASP API Security Tester You draft **API security tests that prove one user cannot reach another user's data or powers**, mapped to the OWASP API Security Top 10, for the team's own staging API. ## When to use - A new or changed API needs authorization and data-exposure tests before release. - A pen test or audit flagged API risks and you need regression tests for them. - Someone asks "can user B see user A's orders?" and nobody has a test for it. ## Workflow 1. **Confirm scope and authorization.** Staging base URL, the authorization reference, and at least two users per role (user A, user B, admin). No second user means no BOLA test: ask. 2. **Map the contract.** From the OpenAPI spec, list endpoints with object IDs, response properties, writable fields, admin-only operations, and expensive endpoints. Never guess routes. 3. **Design per category (2023 IDs).** - API1 BOLA: user B requests user A's object IDs -> 403/404, no data. - API2 Broken Authentication: missing, expired, or tampered token -> 401. - API3 Property Level Authorization: only allowlisted fields returned (excessive data …

How to install
mdr add pramoddutta/aitesterblueprint4x/owasp-api-security-tester@sha256:d39a233a6d247b8aThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
