Scalekit provides a comprehensive authentication and authorization platform specifically designed for AI applications. It allows businesses to secure various interfaces, including SaaS applications, Multi-Cloud Platform (MCP) servers, human users, and AI agents. The platform offers modular authentication products that can be added to existing setups or used as a full-stack identity layer.
Scalekit addresses the unique authentication challenges of AI-driven products by offering features like MCP Auth for LLM clients, delegated access for AI agents to external tools, and enterprise-grade SSO and SCIM provisioning. It also includes full-stack identity features such as organization and user management, passwordless authentication methods, role-based access control, and extensive customization options. The platform is built for flexibility, auditability, and enterprise-grade security, including SOC 2 and ISO 27001 certifications, GDPR/CCPA compliance, and data residency options.
Scalekit is ideal for B2B and AI startups looking to ship production-ready authentication quickly, as well as enterprises needing to migrate from existing CIAM solutions like Auth0 or Okta. It simplifies complex auth implementations, allowing teams to focus on core product features while ensuring secure, scalable, and enterprise-ready authentication.
How does Scalekit's MCP Auth module handle dynamic client authentication without pre-registration?
Scalekit's MCP Auth supports Client ID Metadata Documents (CIMD). This allows for secure authentication of dynamic MCP clients using metadata URLs, eliminating the need for pre-registration or open Dynamic Client Registration (DCR).
Can Scalekit manage user sessions across multiple applications within a single environment?
Yes, Scalekit offers multi-app support, allowing users to sign in once and maintain sessions across various applications. Each application can have its own OAuth client and scopes within that single environment.
What mechanisms does Scalekit provide for AI agents to securely access external tools on behalf of users?
Scalekit's Agent Auth module enables delegated access for AI agents. Users can grant OAuth access, and the system provides an access token vault with scoped retrieval permissions, auto-refreshed short-lived tokens with rotation policies, and auth logs for token activity.
How does Scalekit facilitate the migration of SSO providers without impacting end-users?
Scalekit offers an SSO migration feature that allows for seamless transitions between SSO providers. It preserves IdP settings, intelligently routes requests, and eliminates migration downtime, ensuring no customer reconfiguration is required.
What is included in the 'Scale' plan for the full-stack auth platform regarding active users and organizations?
The 'Scale' plan includes up to 1 million Monthly Active Users (MAU) and 100 Monthly Active Organizations (MAO) for free. A user is counted as active if they log in or sign up once during a billing month, and an organization is active if it has at least two users with one login during the month.
