Architecture for Secure AI Agent Integration and Authentication
As AI agents evolve from prototypes to production workflows, secure, scalable access to third-party tools becomes a foundational requirement. Traditional authentication models—designed for static apps, not autonomous agents—fail in multi-tenant, prompt-driven environments. This whitepaper introduces Fastn’s Unified Context Layer (UCL): a reference architecture purpose-built for secure agent-to-tool orchestration, combining white-labeled OAuth, tenant-scoped token handling, robust observability, flexible authentication strategies, and cost-efficient context caching.

In this whitepaper, you’ll learn how to:
Close security gaps in AI agent authentication
Use UCL’s SDK, Vault, and MCP for secure tool access
Keep context persistent across stateless workflows
Enforce multi‑tenant, per‑user token security
Monitor activity with built‑in observability
Cut latency and costs with caching strategies
Support multiple auth methods beyond OAuth
