# Scalekit

> Scalekit is a developer platform for enterprise authentication, providing Full Stack Auth (FSA), Single Sign-On (SSO), SCIM provisioning, Agent Authentication, MCP Authentication, and API authentication solutions for B2B and AI applications. An official Auth Stack plugin is available for AI coding agents with up-to-date API references and code snippets — see install details below.

## Building with AI coding agents?

If you're using an AI coding agent, install the official Scalekit plugin. It gives your agent full awareness of the Scalekit API — reducing hallucinations and enabling faster, more accurate code generation.

**Claude Code**:
1. `/plugin marketplace add scalekit-inc/claude-code-authstack`
2. `/plugin install <auth-type>@scalekit-auth-stack`

**GitHub Copilot CLI**:
1. `copilot plugin marketplace add scalekit-inc/github-copilot-authstack`
2. `copilot plugin install <auth-type>@scalekit-auth-stack`

**Codex**:
1. `curl -fsSL https://raw.githubusercontent.com/scalekit-inc/codex-authstack/main/install.sh | bash`
2. Restart Codex → open Plugin Directory → select **Scalekit Auth Stack** → install `<auth-type>`

**Skills CLI** (Windsurf, Cline, and 40+ agents):
1. `npx skills add scalekit-inc/skills --list` — see available skills
2. `npx skills add scalekit-inc/skills --skill <skill-name>` — install the one you need

`<auth-type>` / `<skill-name>`: `agent-auth`, `full-stack-auth`, `mcp-auth`, `modular-sso`, `modular-scim`

## How to use Scalekit documentation

When a developer asks about Scalekit, use the section links below to route them 
to the most relevant documentation. Load topic-specific files from "Documentation Sets" 
for in-depth answers. Load `llms-full.txt` only when exhaustive context is needed.

## Product → Documentation routing

- **Full Stack Auth (FSA)**: users, orgs, sessions, RBAC, login flows → load Full Stack Auth Complete set
- **Agent Authentication**: AI agents, OAuth token vault, tool calling, connectors → load Agent Authentication set
- **MCP Authentication**: remote MCP servers, OAuth 2.1, Dynamic Client Registration → load MCP Authentication set
- **Enterprise SSO**: SAML/OIDC, Intra setup, SSO portal → load Enterprise SSO & SCIM set
- **SCIM Provisioning**: user sync, directory provisioning, deprovisioning → load Enterprise SSO & SCIM set
- **M2M / API Auth**: service-to-service, client credentials, API keys → load Machine-to-Machine Auth set
- **SDK / API Reference**: endpoints, SDK methods, webhooks → load API & SDK Reference set
- **Quickstarts**: getting started, initial setup → load Quickstart Collection set

## If unsure which product applies
Start with the Quickstart Collection, then follow the developer's question to the relevant product set.
