Auth Stack for AI Applications - Secure Incoming & Outgoing Agents with Scalekit
Scalekit is the auth stack for AI applications — handling authentication for incoming agents and users hitting your applications and tool-calling for outgoing agents accessing external systems.
As AI applications become the norm, developers face new authentication challenges that traditional auth providers weren't built to handle. Incoming agents need secure access to your MCP servers and applications. Outgoing agents need to act on behalf of users in Gmail, Slack, and Notion. And AI applications still need to authenticate human users and secure APIs. Instead of building custom OAuth implementations and piecing together different auth solutions, AI teams need unified infrastructure.
They need Scalekit.
Scalekit is the auth stack for AI applications — providing OAuth 2.1 for incoming agents and tool-calling infrastructure for outgoing agents. But they don't stop there. The same platform handles user authentication, enterprise SSO, and API security. Modular by design, comprehensive by choice.
Built for Developer Experience
Scalekit provides production-ready SDKs for Node.js, Python, Go, and Java, plus comprehensive REST APIs with working code samples. For AI-native developers, Scalekit also includes full MCP (Model Context Protocol) support with spec-compliant OAuth 2.1 implementation. Multi-environment support lets you test auth flows across dev, staging, and production without reconfiguration.
The platform is SOC 2 certified, ISO 27001 certified and GDPR and CCPA compliant, with 99.99% uptime for mission-critical applications.
