An agent gateway serves as a unified data plane for agentic AI systems, functioning as a proxy that manages communication between agents and their tools. As AI agent deployments scale beyond single instances, they create complex distributed systems requiring centralized governance of network traffic. Similar to traditional API gateways, agent gateways provide consistent routing, authentication, security, and observability across multiple protocols including MCP, LLM, and HTTP/gRPC traffic. This unified approach eliminates the need for individual agents to implement redundant authentication, retry logic, and policy enforcement. AgentGateway, an open-source Apache-licensed project hosted by the Linux Foundation's Agentic AI Foundation, exemplifies this solution by enabling multi-protocol traffic management with centralized discovery, role-based access control, audit logging, token budgeting, and intelligent routing across multiple model providers and self-hosted inference servers.
