Authentication and Credentials for Agentic Workflows

The combined material outlines a solid, multi-token authentication and credential-management pattern appropriate for agent workflows, but it introduces substantial risk if implemented without rigorous security controls. The strongest portions—token rotation, least-privilege modeling, and MCP authentication concepts—are valid, yet require concrete mitigations around logging safety, replay protection, and strict secret-supply-chain governance. Overall risk is moderate to high in deployment unless persistent safeguards and verified endpoints are in place.
