oAuth integration

A unified authentication and authorization stack built on Ory Kratos as the identity provider, seamlessly integrated with the Model Context Protocol (MCP) and existing enterprise platforms. The system supports OAuth 2.0 and OpenID Connect flows, secure token lifecycle management, and delegated access for both human users and autonomous AI agents.

The architecture addresses a critical gap in the AI agent ecosystem: how to provide agents with secure, scoped, and auditable access to enterprise resources without compromising the organization's security posture. Traditional OAuth flows assume a human in the loop for consent screens, but agent-to-service authentication requires a fundamentally different approach. Our solution implements a delegated authorization model where human users grant agents specific capability-bounded tokens with configurable expiration, scope restrictions, and revocation policies.

The system ensures scalable identity federation, fine-grained permissions, and consistent governance across distributed agentic and human workflows. It includes a centralized policy engine that evaluates access requests against organizational rules in real time, a token introspection service for downstream services to verify agent permissions, and comprehensive audit logging that captures the full chain of delegation from human user to agent to resource access. The implementation supports multi-tenant deployments with tenant-isolated identity stores and configurable federation policies for cross-organization collaboration.
