What agentgateway does
Open-source proxy for MCP and A2A with multiplexing, authorization, and OpenTelemetry.
Why teams reach for it: It centralizes access to multiple MCP servers and applies authorization policies at the gateway.

A gateway or proxy sits between clients and MCP servers to route traffic or add a control layer, without changing the servers themselves.
