Scalekit

Scalekit is the auth stack for B2B AI apps. Secure human users with SSO, SCIM, passkeys, magic links, social login, and OTP. Secure AI systems in both directions: MCP Auth controls who can access your MCP servers, and Agent Auth lets your agents connect to third-party tools through OAuth 2.1 with scoped, consented tokens, backed by 50+ prebuilt connectors and a built-in Token Vault. Everything runs on a multi-tenant foundation. Users, agents, and MCP servers share the same tenancy boundary, so access controls and identity configuration stay consistent across your entire product. Use Scalekit as your complete auth stack, or add it alongside Auth0, Firebase, or whatever you already have. No user migration required. Why Scalekit: 1. Purpose-built for B2B AI: Multi-tenancy with shared users across orgs, identity deduplication, domain-based routing, and per-organization SSO and SCIM configuration. Human users, MCP servers, and agents (on behalf of users or orgs) all operate within the same tenancy boundary, so access controls, token policies, and identity configuration stay consistent across every principal in your product. 2. Full-stack or modular: Use Scalekit end-to-end with users, sessions, roles, and hosted UI, or drop in just SSO, SCIM, MCP Auth, or Agent Auth alongside an existing system. No user migration required. 3. Customizable and extensible: Branded hosted widgets, custom domains, custom email templates, auth flow interceptors, webhooks, and flexible APIs. 4. Batteries-included developer tooling: Prebuilt SDKs, quickstarts, multi-environment support, auth logs, IdP simulators, and migration guides. Founded in 2024, Scalekit is backed by Matrix Partners and Together Fund.
