What is the difference between Full-Stack Auth and Modular SSO?

Full-Stack Auth is for when Scalekit handles your entire identity system. Modular SSO is designed to add enterprise login (SAML/OIDC) to your existing authentication setup without requiring a user migration.

How does this skill help with security best practices?

It provides standardized patterns for HttpOnly cookie storage, server-side token validation, and CSRF protection to ensure your authentication implementation is production-grade.

Which programming languages and frameworks are supported?

The skill currently provides production-ready templates and SDK integration for Node.js (Express, Next.js) and Python (FastAPI), with support for Go and Django in development.

Can I use this skill to secure MCP servers?

Yes, it includes a dedicated implementation path for OAuth 2.1, which is the standard for securing Model Context Protocol servers used by clients like Claude Desktop and Cursor.

Security & Testing

Implements secure authentication, enterprise SSO, and MCP server OAuth 2.1 flows using Scalekit across various web frameworks and APIs.

Scalekit Authentication is a comprehensive Claude Code skill designed to streamline the implementation of identity management in modern applications. It provides pre-configured paths for building full-stack authentication from scratch, integrating modular enterprise SSO (SAML/OIDC) into existing systems, and securing Model Context Protocol (MCP) servers with OAuth 2.1. By offering framework-specific templates for Node.js, Next.js, and Python, the skill ensures developers can rapidly deploy secure login flows, session management, and role-based access control while adhering to security best practices like HttpOnly cookies and server-side token validation.
