Scalekit Auth Plugins for Claude Code — the auth stack for agents.
Add SSO, SCIM, MCP Auth, agent auth, and tool-calling from your Claude Code editor.
Setting up auth for B2B and AI apps is complex. Between auth flows, SSO providers, SCIM provisioning, MCP auth, and securing AI agents, most developers spend weeks on auth instead of shipping features with confidence.
This plugin adds the complete Scalekit auth stack to your projects — whether that's a B2B app, AI agent, or MCP server — directly from Claude Code.
Installation
# Start Claude REPL

# Add Scalekit Auth Stack marketplace
/plugin marketplace add scalekit-inc/claude-code-authstack
# Run the plugins wizard

Available Plugins
| Plugin | Description |
|---|---|
| Dryrun | Validate auth and provisioning flows before deployment. Test your configuration against real identity providers without touching production. |
| MCP Auth | Add OAuth 2.1 authorization to Model Context Protocol servers. Guides you through token handling, refresh flows, and scope management. |
| Modular SSO | Integrate enterprise SSO providers (Okta, JumpCloud, Entra ID, etc.). Support 20+ identity providers without writing SAML parsers. |
| Modular SCIM | Enable user provisioning and directory sync. Let customers provision users automatically from their identity provider. |
| Full Stack Auth | Complete authentication setup for web applications. End-to-end auth including login pages, session management, and protected routes. |
| Agent Auth | Secure authentication for AI agents and services. OAuth flows designed for AI agents with token persistence and refresh logic. |
