The-CarL/exploring-agent-auth

This project is a high-quality educational resource rather than a defensible product. With 0 stars and a 2-day-old history, it represents a 'point-in-time' exploration of a critical problem: how agents safely access tools. Its value lies in the structured comparison of patterns (Shared Credentials vs. On-Behalf-Of vs. Scoped Tokens). However, it lacks a moat; the patterns use commodity infrastructure (Keycloak, OPA). The most significant threat is the Model Context Protocol (MCP) by Anthropic and similar efforts by OpenAI/Microsoft to standardize agent-tool interaction at the protocol level. These frontier labs have a vested interest in defining the security layer to ensure their models can be safely deployed in enterprises. Furthermore, platform giants like Microsoft (Entra ID) and Okta are already extending their IAM capabilities to service identities and 'non-human entities,' which will likely absorb the functionality demonstrated here. Within 6 months, standardized libraries or platform-native features will likely make these manual OPA/Keycloak configurations obsolete for all but the most custom legacy enterprise environments.
