Deep-audit checks for OAuth 2.0, OIDC, and SAML federation covering flow misuse, redirect_uri validation, state and PKCE handling, token and assertion verification, IdP-side misconfiguration, and session-bridging flaws up to account takeover.

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

# OAuth 2.0 / OIDC / SAML Federation Checks

## Scope & Objectives

Run this module when the repo contains federation code or configuration. Triggers include any of:

- Client/RP libraries: `passport`/`passport-*`, `omniauth(-*)*`, `authlib`, `flask-dance`, `social-auth-core`, `django-allauth`, `python-jose`, `PyJWT` used on id_tokens, `spring-boot-starter-oauth2-client`, `spring-security-saml2-service-provider`, `Microsoft.AspNetCore.Authentication.OpenIdConnect`/`Cookies`/`JwtBearer`, `Microsoft.Identity.Web`, `next-auth`, `express-openid-connect`, `oauth4webapi`, `angular-oauth2-oidc`, `keycloak-js`, `@auth0/auth0-*`/`auth0-spa-js`, `@okta/*`.
- IdP-side artifacts: Keycloak realm-export JSON, Auth0 tenant/rules/actions config, Okta org YAML, ADFS/WIF settings, `doorkeeper`, `keycloak` services, custom `/authorize`, `/token`, `/jwks` handlers.
- SAML stacks: `passport-saml`, `samlify`, `saml2-js`, `ruby-saml`, `python3-saml`, OneLogin SDKs, Shibboleth SP (`shibboleth2.xml`, `attribute-map.xml`), pac4j, Spring SAML.

How to install

The exact contents, by fingerprint
mdr add as-foss/aegis-skills/aegis-oauth-sso@sha256:8fa235c5228fab86

The line at the top of this page pins the label git:20260826.9702747, 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.
