Show HN: Agentic Identity Broker, OAuth Delegation for AI Agents

Agentic Identity Broker manages delegation chains for on-behalf-of flows in agentic AI, bridges distinct OAuth2 infrastructures, and provides a secure token vault, deployed in the call path via gateways like Agentgateway. It handles OAuth2 ceremonies, token vaulting and token translation centrally so MCP server developers only need to provide tools, and it offers consent management, audit logging, and an impersonation feature for delegation chains without user presence. The project is in active development and used internally in production for several MCP servers.
