Automated safety checks
This skill failed 2 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.
No undeclared network calls: failed
Contacts 1 host that is neither well-known infrastructure nor declared in the skill's frontmatter: mcp.cloudflare.com.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

About this skill
What it does
This skill integrates Auth0's identity solutions into Express.js web applications using the express-openid-connect package. It simplifies adding authentication features like login, logout, and user profile information to your Node.js backend. The integration automatically creates necessary endpoints for OAuth flows, making secure user management easier for developers.
When to use it
- Adding authentication to existing Express.js web applications.
- Building new Express.js-based backends that require user login and authorization.
- When you want to leverage Auth0's identity platform without extensive custom coding.
- For projects where session-based authentication is appropriate (as opposed to JWT validation).
Key capabilities
- Automatic creation of
/login,/logout, and/callbackendpoints. - Integration with Auth0 for user authentication and authorization.
- Provides access to authenticated user profile information via
req.oidc.user. - Supports both login and logout functionality.
- Allows specifying configuration parameters like client ID, secret, issuer base URL, and base URL through environment variables.
Example prompts
- "Add Auth0 authentication to my Express.js application."
- "Create a protected route that requires user authentication using Auth0."
- "Configure the Auth0 middleware with my application's client ID and secret."
Tips & gotchas
- Requires an existing Express.js application and a configured Auth0 account and application.
- This skill is not suitable for Single Page Applications (use
auth0-react,auth0-vue, orauth0-angularinstead), Next.js applications (useauth0-nextjs), mobile apps (useauth0-react-native), or stateless APIs/microservices (consider JWT validation). - Environment variables like
SECRET,BASE_URL,CLIENT_ID,CLIENT_SECRET, andISSUER_BASE_URLmust be configured correctly.
