Is an LLM gateway a control plane if agents can just bypass it?
Arc_bong · reddit · 2026-09-09
A Reddit post argues LLM gateways (LiteLLM, Portkey, OpenRouter) control traffic, not paths: any agent with credentials and network access can call providers, MCP endpoints, or other egress directly, so the gateway is a component of agent governance rather than the boundary. The proposed architecture pairs an agent gateway with egress enforcement, identity, and shadow discovery; the author asks what actually prevents bypass in production.
