Implement secure API design patterns including authentication, authorization, input validation, rate limiting, and protection against common API vulnerabilities.
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
# API Security Best Practices Review the request boundary from caller identity through authorization, validated input, storage and observable response. Preserve the application's actual identity provider and data model rather than introducing a second authentication system. ## When to Use Use when adding a protected endpoint, reviewing object access, replacing permissive request parsing, or investigating an API abuse path. For a concrete defect, start with the failing route and its callers; do not deploy unrelated security infrastructure. ## Inputs and prerequisites Record the routes, caller/tenant model, identity provider, token contract, runtime and locked dependency versions, database schema, proxy topology and authorized test scope. Use synthetic identities in a test environment. Existing task authorization carries forward; production scans, account writes and message sends need their own authority. The Node examples below are integration sketches for Express, jsonwebtoken and Zod; application/database adapters are deliberately named rather than presented as a full runnable service. Confirm APIs against the installed versions before integrating. …

How to install
mdr add b-mendoza/agent-skills/api-security-best-practices@sha256:f01d39fb4e2a134fThe line at the top of this page pins the label git:20260906.abc8529, 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.
