Navigating SAP's Agent Architecture: MCP for Tool Execution, A2A for Orchestration
SillyDot3305 · reddit · 2026-08-05
Developers are trying to integrate external agents with SAP systems but often find themselves lost in a sea of overlapping terminology. The author clarifies the current architectural understanding: MCP Gateway is primarily used to expose APIs as tools for agents to invoke, while A2A (Agent-to-Agent) focuses on delegation, context passing, and outcome returns between agents.
The main pain point with SAP's current ecosystem (Joule, BTP, Agent Gateway) is the blurred lines between production-ready tools and roadmap positioning. The author calls on developers with hands-on POC experience to share insights on auth, governance, observability, and tool lifecycle management.
